Description

[0001] COATED FABRIC ARTICLES This disclosure relates to coated fabric articles, such as airbags and airbag fabric articles coated with the cured product of a hydrosilylation curable silicone rubber coating composition containing preformed silicone elastomeric particulates and to a method of coating said articles, e.g., airbags or airbag fabric articles with the hydrosilylation curable silicone rubber coating compositions containing said preformed silicone elastomeric particulates. Textiles and fabrics are often treated with one or more coatings in order to provide them with a variety of properties. Silicone coating compositions are used to provide textiles and / or fabrics with a wide variety of different properties. One of the main applications for treated textiles and fabrics is for use in or as inflatable safety restraint devices, especially airbags. Airbags are widely used to cushion vehicle occupants in the event of collisions and accidents. They are designed to protect drivers and passengers from being injured between an initial impact and further impacts, by their inflation in within 0.02-0.12 seconds of the initial impact during a traffic accident. Inflatable safety restraint devices such as airbags, generally consist of a textile or fabric bag (sometimes referred to as a cushion), a sensor and a means of inflation. In the event of an accident, a sensor within a vehicle identifies an abnormal deceleration and triggers the inflator causing an effectively immediate inflation of the airbag. Expanding gases travel through conduits and inflate the airbag(s), to cushion the vehicle occupant (driver or passenger) and protect them from any further harmful impact within the interior of the vehicle, e.g., a car. Airbags and / or airbag fabric articles may be made from woven or knitted fabric made of synthetic fibres, for example thermoplastics such as polyamides e.g., nylon-6,6, or polyesters such as polyethylene terephthalate (PET) and benefit from the application of silicone coating compositions, which upon cure typically provides silicone elastomeric coatings having a low modulus, a high elongation, a low coefficient of friction, and / or a high flame resistance of silicone elastomers. Such properties may improve airbags in a number of ways including: 1) improved thermal protection from hot gases and particulates (600oC to 1,000oC) generated during airbag expansion using for pyrotechnic generators; 2) improved flame-resistance of fabric; 3) improved resistance to bag deflation; 4) improved resistance to stresses when airbag cushions are deployed; and 5) softness and lightness of silicone coatings provide airbags with very good flexibility, enabling them to be folded into a more compact module. The airbags may be made from flat fabric pieces which are coated and then sewn together to provide sufficient mechanical strength or may be woven in one piece (generally referred to as “one-piece woven” or OPW) with integrally woven seams. Sewn flat fabric airbags are generally assembled with the coated fabric surface at the inside of the airbag but may be coated on the insider and / or outside. One-piece woven airbags are coated on the outside of the airbag. Some airbags are designed to retain gas pressure after deployment, so they remain inflated for longer periods of time after a collision or the like, e.g., side-curtain airbags. These tend to be, but are not exclusively, one-piece woven airbags. Today, it is generally compulsory to have several airbags in vehicles as a means of providing safety to the occupants in the event of a collision. They include frontal airbags, front-centre airbags, side airbags, side-curtain airbags, thorax airbags, and / or knee airbags. Typically, the airbags are concealed within the vehicle trim to be invisible during normal vehicle operation. For example, frontal airbags may be installed in the steering wheel on the driver's side of a vehicle, and in the dashboard on the passenger side of the vehicle. They are provided to act as a cushion at a point of impact especially in collisions with the front or back of the vehicle. They exhibit relatively high air permeabilities to allow the expanded airbag to quickly deflate after the initial impact. Typically, these airbags are flat fabric pieces sewn together. Side-curtain airbags are increasingly utilized and are most often mounted within the headliner above the doors and windows and deploy along the side window from the vicinity of the ceiling to protect vehicle occupants from a side collision and consequent rollover incidents (where the vehicle tips over onto its side or upside-down or flips over more than once). Because of this, side-curtain airbags, are designed to retain their inflated state for a long duration (for example, exhibiting a retention of at least 50% of the initial pressure after 5 seconds subsequent to high pressure inflation) i.e., they need to retain large amounts of gas, as well as high gas pressures, throughout the longer time periods of the entire potential rollover. They generally unroll from packing containers stored within the roofline along the side windows of an automobile (and thus have a back and front side only). Side-curtain airbags therefore not only provide cushioning effects but also provide protection from broken glass and other debris. One-piece woven type airbags are usually used for side-curtain airbags in combination with silicone sealant coatings in order to provide the low permeability (and thus longer gas escape times) necessary for side-curtain airbags. Silicone coatings used on airbags are not only designed to prevent air leakage but also to keep the airbags flexible and resistant to temperature fluctuations, aging and abrasion. They need such properties because, for example, an airbag may remain unused for a long period of time before a collision triggers deployment. This requires the silicone coating to be very stable over time in order to prevent the airbag from becoming stuck and to ensure smooth deployment even after many years. Hence, coated fabric articles, such as airbags and airbag fabric articles coated with the cured product of a hydrosilylation curable silicone rubber coating composition provide the user with many advantages due to their physical properties. However, vehicle manufacturers and original equipment manufacturers (OEMs) who supply the automotive industry are continually seeking to meet lower and lower “carbon footprint” reduction targets in the manufacture of vehicles. Hence, there is a need to both reduce the carbon footprint associated with producing new silicone compositions used to generate silicone elastomers, such as coatings for airbags. Given they are thermoset materials, silicone elastomers cannot be melted and reprocessed into polymers which are suitable to be used in their intended applications and as such it is difficult to provide an effective recycling and / or reclaiming alternative to incineration or landfilling as an end- of-life option to meet the desired “carbon footprint” reduction targets with respect to the manufacture of vehicular airbags and the like. There are two main method types for recycling / reclaiming elastomeric materials these tend to be via “chemical processes” such as pyrolysis, chemical degradation and chemical reversion and by “physical processes”, i.e., mechanical processes such as mechanical reclaiming, thermo-mechanical reclaiming and cryo-mechanical reclaiming and wet / solution grinding methods. Given silicone elastomers are thermoset materials chemical recycling of silicone elastomers is not ideal because reclaiming / recycling requires significant separation and often generate solid residues that are typically of low value. It is known however that particulates made from elastomeric silicone materials may be prepared and one means of achieving this is by recycling and / or reclaiming. That said, such recycled and / or reclaimed silicone elastomeric particulates are typically incorporated as fillers in conjunction with a binder material that serves as a matrix. The binder can be either a new silicone composition or an organic polymer material that can also be combined with an inorganic mixture such as an asphaltic or cementitious mixture and serves the function of entrapping and / or encapsulating the discrete particles. However, they have not been considered useful in higher value applications because of their inconsistency and variability in performance and therefore the value proposition for such recycled and / or reclaimed silicone elastomeric particulates is poor with the particulates only being deployed in lower value applications, lowering economic and technological incentives for reuse, as a result of: (i) poor incorporation of the silicone elastomeric particulates within the binder matrix; (ii) Interfacial adhesion and binding between the silicone elastomeric particulates and matrix being typically poor such that the preformed silicone elastomeric particulates can serve as defects in the matrix, creating voids, surface protrusions or other heterogeneities in the matrix resulting in inferior properties to new silicone elastomers. A more sustainable liquid silicone rubber (LSR) coating composition is provided for use in the manufacture of the silicone rubber coated airbags described herein which provides a lower carbon footprint by enabling replacement of a significant amount of new liquid silicone composition (greater than (>) 10 wt. %) with preformed silicone elastomeric particulates which may be recycled and / or reclaimed. It was surprisingly found that the varying sources of preformed silicone elastomeric particulates, be they recycled or reclaimed or otherwise obtained, were unexpectedly compatible with the hydrosilylation curable airbag coating compositions used to make the coated airbag and coated airbag materials. There is provided herein a coated fabric article comprising: i) a substrate having a surface, wherein the substrate comprises a fabric suitable for making an airbag; ii) a cured product of a hydrosilylation reaction curable silicone rubber coating composition adhered on the surface of the substrate, wherein the hydrosilylation reaction curable silicone rubber coating composition comprises a) one or more organopolysiloxane polymer having a viscosity of between 100 and 200,000mPa.s inclusive at 25 ºC, and at least two unsaturated groups per molecule, which unsaturated groups are selected from alkenyl and / or alkynyl groups; b) optionally one or more reinforcing fillers comprising fumed silica, precipitated silica and / or calcium carbonate; c) an organosilicon compound having an average of at least two or alternatively an average of at least three Si-H groups per molecule; d) a hydrosilylation cure catalyst; e) preformed silicone elastomeric particles (e)(i) having an average unswollen particle size of 1 mm or less, which preformed silicone elastomeric particulates (e)(i) have been penetrated and swollen by an organopolysiloxane polymer swelling agent (e)(ii) having a zero-shear viscosity of less than or equal to (≤) 15,000 mPa.s at 25oC; f) an adhesion promoter; and optionally g) one or more silicone resins selected from T silicone resins (silsesquioxanes), DT silicone resins, MQ silicone resins, MDT silicone resins, MTQ silicone resins, QDT silicone resins or mixtures thereof. In one embodiment the fabric article is an airbag or an airbag fabric article. There is also provided a method of coating a fabric article comprising the steps of (1) Mixing preformed silicone elastomeric particulates (e)(i) having an average unswollen particle size of 1 mm or less, with an organopolysiloxane polymer swelling agent (e)(ii) having a zero-shear viscosity of less than or equal to (≤) 15,000 mPa.s at 25oC to enable said organopolysiloxane polymer swelling agent (e)(ii) to penetrate and swell said preformed silicone elastomeric particulates (e)(i) to form component (e); (2) forming a step (2) mixture comprising component (e) and at least part of component (a) and optionally one or more of components (c), (d), (f) and when present (b), (g) or (b) and (g) wherein a) is one or more organopolysiloxane polymer having a viscosity of between 100 and 200,000mPa.s inclusive at 25 ºC, and at least two unsaturated groups per molecule, which unsaturated groups are selected from alkenyl and / or alkynyl groups; b) is optionally one or more reinforcing fillers comprising fumed silica, precipitated silica and / or calcium carbonate; c) is an organosilicon compound having an average of at least two, or alternatively an average of at least three Si-H groups per molecule; d) is a hydrosilylation cure catalyst; f) is an adhesion promoter; and optionally g) one or more silicone resins selected from T silicone resins (silsesquioxanes), DT silicone resins, MQ silicone resins, MDT silicone resins, MTQ silicone resins, QDT silicone resins or mixtures thereof; (3) mixing the step (2) mixture with the remainder of components (a), (c), (d), (f),and when present (b), (g) or (b) and (g) to produce a hydrosilylation curable silicone rubber coating composition; (4) applying the hydrosilylation curable silicone rubber coating composition on to a substrate having a surface, wherein the substrate comprises a fabric suitable for making an airbag; (5) curing said coating on said substrate having a surface, wherein the substrate comprises a fabric suitable for making an airbag for a predetermined time at a temperature of between 100oC and 200oC. In one embodiment step (1), step (2) and optionally step (3) may be undertaken together as a single step. There is also provided herein a coated fabric article coated with a cured product of a hydrosilylation curable silicone rubber coating composition made in accordance with the above method. In one embodiment the fabric article is an airbag or an airbag fabric article. There is also provided a use of preformed silicone elastomeric particulates (e)(i) having an average unswollen particle size of 1 mm or less, which preformed silicone elastomeric particulates (e)(i) have been penetrated and swollen by an organopolysiloxane polymer swelling agent (e)(ii) having a zero-shear viscosity of less than or equal to (≤) 15,000 mPa.s at 25oC; in a hydrosilylation curable silicone rubber coating composition otherwise comprising: a) one or more organopolysiloxane polymer having a viscosity of between 100 and 200,000mPa.s inclusive at 25 ºC, and at least two unsaturated groups per molecule, which unsaturated groups are selected from alkenyl and / or alkynyl groups; b) optionally one or more reinforcing fillers comprising fumed silica, precipitated silica and / or calcium carbonate; c) an organosilicon compound having an average of at least two or alternatively an average of at least three Si-H groups per molecule; d) a hydrosilylation cure catalyst; f) an adhesion promoter; and optionally g) one or more silicone resins selected from T silicone resins (silsesquioxanes), DT silicone resins, MQ silicone resins, MDT silicone resins, MTQ silicone resins, QDT silicone resins or mixtures thereof; for coating a fabric article comprising a substrate having a surface, wherein the substrate comprises a fabric suitable for making an airbag. In one embodiment the fabric article is an airbag or an airbag fabric article. For the avoidance of doubt the term average unswollen particle size is intended to mean the average particle size subsequent to preparation prior to mixing with a “swelling agent” otherwise identified as component (e)(ii) and / or organopolysiloxane polymer (e)(ii). The preformed silicone elastomeric particulates (e)(i) may be made from new compositions or are physically recycled and / or reclaimed silicone elastomeric particulates (e)(i). In one embodiment the preformed silicone elastomeric particulates (e)(i) are physically recycled and / or reclaimed silicone elastomeric particulates (e)(i). The terms recycling and reclaiming as used herein are intended to define the function of recovering and converting waste materials into new materials and usable products. The term “average unswollen particle size” is intended to mean the average particle size of particulates irrespective to their method of preparation prior to mixing with a “swelling agent” otherwise identified as component (e)(ii) and / or organopolysiloxane polymer (e)(ii). For example, in the case of physically recycled and / or reclaimed silicone elastomeric particulates (e)(i) it is the average particle size of particulates subsequent to physically recycling and / or reclaiming the source of the silicone elastomer particulates (e)(i) and prior to mixing with a “swelling agent” otherwise identified as component (e)(ii) and / or organopolysiloxane polymer (e)(ii). The use of recycled / reclaimed silicone elastomer particulates (e)(i) provides a more sustainable hydrosilylation cured silicone rubber coating for fabric articles, particularly airbags and airbag fabric articles, offering a lower carbon footprint to the user by enabling replacement of a significant amount of new liquid silicone compositions, e.g., 10wt. % or more of the composition, with mechanically recycled cured silicone elastomer particulates, from a variety of sources, sufficiently compatible with hydrosilylation curable silicone rubber coating compositions which provide useful elastomeric properties to the coating. Hence, this solution provides both the benefit, of reducing the carbon footprint associated with producing new hydrosilylation cured silicone rubber coatings on coated fabric articles such as airbags and airbag fabric pieces, as well as providing a high value alternative to incineration or landfilling as an end-of-life option for the silicone elastomers used in the preparation of the preformed silicone elastomeric particulates. The ability to penetrate and swell the preformed silicone elastomeric particulates (e)(i) with an organopolysiloxane polymer swelling agent (e)(ii) as described above results in the formation of interpenetrating networks between the new silicone composition and the preformed silicone elastomeric particulates, resulting in of the presence of preformed silicone elastomeric particulates of varying origin without substantial degradation in mechanical properties (and potentially even “upcycling” through improved properties) of the resulting elastomeric coatings on the airbags and / or airbag fabrics coated herein. This has a direct benefit on the Life Cycle Assessment (LCA) of the coating compositions by replacing carbon dioxide equivalence which goes into the making of the ingredients which go into the hydrosilylation curable silicone rubber coating composition with a mechanically recycled material that does not require capital- and energy-intensive molecular level purification steps like distillation. Preformed silicone elastomeric particulates (e)(i) The Preformed silicone elastomeric particulates (e)(i) may be made as new particulates or may be derived from a recycling / reclaiming process derived from any suitable source such as post-industrial or post-consumer waste mainly obtained from condensation cured (RTV) silicone elastomers formerly used as adhesives, refrigerant spacers, potting agents coatings and sealants such as weatherproofing sealants and coatings and / or tire sealants or silicone rubber elastomers prepared from hydrosilylation curable compositions, peroxide free-radical cure compositions or UV cure compositions using photoinitiators or photo-catalysts, which elastomers may have been used in applications such as airbag coatings, gaskets and seals adhesives, coatings, foams, molded rubber articles, hoses and tubing like medical tubing, encapsulants and potting agents or the like. The original elastomer and the resulting physically recycled and / or reclaimed silicone rubber particulates may be dense or have inclusions or voids, as in foams. However, silicone elastomers made from any suitable cure system may be utilised as the source of preformed silicone elastomeric particulates. Newly made particulate used as preprepared silicone elastomeric particulates herein may be made from condensation cured (RTV) silicone elastomer compositions or prepared from hydrosilylation curable compositions, peroxide free-radical cure compositions or UV cure compositions using photoinitiators or photo-catalysts, which may be obtained via their usual curing process into slabs / lumps or the like and then are physically (e.g., mechanically) ground, attrited or otherwise reduced in size into discrete particulates using a grinding device as described elsewhere herein or wherein the curable silicone composition may be cured into particulates by spraying using a spraying device such as a spray drier; or by dispersed and curing the compositions in an aqueous surfactant solution. The latter are often preferred due to their ability to form spherical cured silicone particulates. When the preformed silicone elastomeric particulates are the result of physical recycling or reclaiming. Physical recycling methods are utilised to transform silicone elastomers into powders, granules, crumbs, or pellets (referred to collectively herein as “particulates”). The source of the silicone elastomers may be from, for example, post-industrial scrap or waste rubber, pre-consumer scrap or waste rubber, or post-consumer scrap or waste rubber. For the avoidance of doubt and for the sake of this disclosure physically ( mechanically) recycled / reclaimed particulates have their original crosslinked structure preserved, whereas chemically recycled materials do not. When the origin of the cured silicone rubber elastomeric particulates is unknown a priori, the cured rubber from which it originates or the physically recycled or reclaimed particulates can be characterized by a variety of known methods to ascertain the composition including spectroscopic techniques including infrared techniques such as Fourier transform infrared (FTIR) spectroscopy, attenuated total reflectance infrared spectroscopy (ATR-IR), infrared microscopy, Raman spectroscopy, Raman microscopy, solid state nuclear magnetic resonance (NMR) spectroscopy; chemical derivatization and titration techniques; chemical digestion followed by chromatography such as gas chromatography (GC), gas chromatography-mass spectrometry (GC-MS), liquid chromatography (LC), or by a variety of known elemental or ion analysis techniques such as inductively coupled plasma-optical emission spectroscopy (ICP-OES), x-ray fluorescence (XRF), and neutron activation analysis (NAA). When the preformed silicone elastomeric particulates are physically recycled or reclaimed silicone elastomeric particulates, any suitable physical recycling method including mechanical reclaiming, thermo-mechanical reclaiming, cryo-mechanical reclaiming, and wet / solution grinding can be utilised to obtain the particulates. Examples of methods which may be utilised to generate the particulates include, for the sake of example, cryomilling (at liquid nitrogen temperatures), using milling equipment known in the art such as ball mills, pin mills, and the like, tornado milling (which can be done at either ambient or cryogenic temperatures in the solid state) and wet jet milling (e.g., wet jet) where the rubber is pulverized by an intense water stream. The preformed silicone elastomeric particulates have an average particle size of 1 mm or less. Smaller particle sizes are preferable to minimize stress-concentrating defects in the new article, but satisfactory performance has been achieved even for relatively large 1 mm sized milled preformed silicone elastomeric particulates. In one embodiment the average particle size of the preformed silicone elastomeric particulates was 600µm or less, alternatively the average particle size of the preformed silicone elastomeric particulates was 500µm or less, alternatively the average particle size of the preformed silicone elastomeric particulates was 400µm or less, alternatively the average particle size of the preformed silicone elastomeric particulates was 300µm or less, alternatively the average particle size of the preformed silicone elastomeric particulates was 200µm or less. Particulates of an acceptable size may be obtained by mechanical screening through a sized mesh. Smaller particles are obtained by filtering through increasingly small meshes. In one embodiment the aforementioned silicone elastomeric particulates are physically recycled and / or reclaimed silicone elastomeric particulates (e)(i). If the silicone elastomer to be made into physically recycled or reclaimed particulates is adhered to another material in prior use, they are preferably separated or delaminated. For example, in the case of wanting to recycle airbag articles the first step is to recover the silicone elastomer by delaminating same from the textile / fabric support. After which the resulting coating may be broken down into particulates using one of the physical (mechanical) processes listed above. However, it is to be understood that delamination or separation of silicone materials from certain substrates or articles may be imperfect and can lead to some residual minority fraction of adventitious non- silicone contaminants in the resulting physically recycled and / or reclaimed silicone elastomeric particulates (e)(i)., such as small fragments of fabric or plastic substrates that may be present in quantities less than 10 wt. % of a particulate mixture, preferably 5 wt. % or less, with less being desirable. Physical recycling and / or reclamation using one or more of the different methods described above offers 1) the advantage of being able to reuse inorganic fillers, 2) the ability to incorporate contaminated feedstocks from deployed silicone elastomers, and the ability to tolerate residual Si-H from hydrosilylation cured silicone elastomers without needing to undergo the depolymerization, neutralization, filtration, and stripping steps associated with chemical recycling processes. In one example, cured silicone rubber samples were shredded with a paper shredder or cut with scissors until they were of a predetermined size e.g., less than 2cm particle size before being fed to a mill such as a MikroTMUMP-B mill commercially available from Hosokawa Micron Corporation. The shredded / cut rubber samples can be mixed with dry ice (which may be crushed to a powder using mortar and pestle) in an approximately 1:1 weight ratio in order to reduce the temperature of the rubber and help stiffen it for milling. The rubber / dry ice mixture can then be fed into a suitable mill using a knife blade rotor rotating at an rpm of > 10,000. The rubber can then be allowed to leave the milling chamber through a stainless-steel screen when the rubber is cut finer than the hole size of the screen, e.g., a 2-3 mm diameter round holes could be used for a first pass. The rubber milled in the first pass can then undergo a second pass with dry ice again as before and fed through the MikroTMUMP-B mill for a second pass this time using a 1mm slotted screen. If desired for more accurate particle size measurements samples can be measured using laser diffraction with e.g., a Beckman CoulterTMLS 13320 Particle Size Analyzer with the Tornado (dry) module commercially available from Beckman Coulter Inc., relying on the Beckman CoulterTMsoftware to deconvolute the diffraction signal to a particle size distribution determined using Fraunhofer diffraction model. Penetration and Swelling of the preformed silicone elastomeric particulates (e)(i) with an organopolysiloxane polymer swelling agent (e)(ii) having a zero-shear viscosity of less than or equal to (≤) 15,000 mPa.s at 25oC. As discussed above the preformed silicone elastomeric particulates (e)(i) in the hydrosilylation curable silicone rubber coating composition which is cured herein have an average unswollen particle size of 1 mm or less. However, the recycled and / or reclaimed preformed silicone elastomeric particulates (e)(i) are not just mixed directly into a standard hydrosilylation curable silicone rubber coating composition to be encapsulated therein as the composition cures. They are initially immersed and / or soaked in a low viscosity organopolysiloxane polymer having a zero-shear viscosity of less than or equal (≤) to 15,000 mPa.s at 25oC (e)(ii), alternatively a zero-shear viscosity of from 100 to 13,000 mPa.s at 25oC (e)(ii), alternatively a zero-shear viscosity of from 100 to 10,000 mPa.s at 25oC (e)(ii), alternatively a zero-shear viscosity of from 100 to 7,500 mPa.s at 25oC (e)(ii), alternatively a zero-shear viscosity of from 100 to 5,000 mPa.s at 25oC (e)(ii), alternatively a zero-shear viscosity of from 100 to 2,000 mPa.s at 25oC (e)(ii). Examples of (e)(ii) include vinyl dimethyl terminated Divinyl-functional polydimethylsiloxanes, hydroxyl terminated polydiorganosiloxanes, alkoxy terminated polydiorganosiloxanes or siloxane cross-linkers as defined as component (c) herein such as a polymethylhydrogen dimethylsiloxane copolymers. They may also be unreactive silicone plasticizers such as trimethyl terminated polydimethylsiloxanes. The organopolysiloxane polymer swelling agent (e)(ii) is present in the hydrosilylation curable silicone rubber coating composition in an amount of from about 1.0 to 5.0wt. % of the composition. The preformed silicone elastomeric particulates (e)(i) may or may not be reactive with the organopolysiloxane polymer having a zero-shear viscosity of ≤ 15,000 mPa.s at 25oC (e)(ii), equally it may or may not be reactive with components of the coating composition in which it is to be situated. It was found that the inclusion of a pre-cured phase of preformed silicone elastomeric particulates (e)(i), within a second curable network with an organopolysiloxane polymer having a zero-shear viscosity of ≤ 15,000 mPa.s at 25oC (e)(ii) capable of penetrating and swelling the preformed silicone elastomeric particulates (e)(i), provides a means of forming double networks or inter- penetrating networks (IPNs). Without being bound to currently held theories it is believed that the preformed silicone elastomeric particulates component (e)(i) consists of a pre-cured cross-linked “mesh” component and composition of which component (e)(ii) forms a part also forms a cross- linked network and because of the ability for component (e)(ii) to penetrate and swell component (e)(i), the two networks physically entangle so that there is physical engagement rather than mere encapsulation. It was found that the lower the viscosity value of component (e)(ii) the greater the penetration and swelling of component (e)(i) occurred. Furthermore, penetration and swelling did not occur or occurred minimally when the component (e)(ii) had a zero-shear viscosity of greater 15,000 mPa.s at 25oC. Components (e)(i) and (e)(ii) were compatible, so there appeared to be no problems with component (e)(ii) penetrating into and swelling component (e)(i) providing the zero-shear viscosity of component (e)(ii) was within the range stated. However, given preformed silicone elastomeric particulates (e)(i) are thermoset materials, due to their crosslinked nature, they are unable to dissolve in component (e)(ii). So, the silicone elastomeric particulates (e)(i) instead swell to accommodate the organopolysiloxane polymer of component (e)(ii). The preformed silicone elastomeric particulates (e)(i) are thus physically well bound in the matrix and cannot serve as defects in the matrix, which could result in voids, surface protrusions and / or other heterogeneities which is often a problem when merely encapsulated and used as a filler. In a first embodiment, the preformed silicone elastomeric particulates (e)(i) may be penetrated and soaked in organopolysiloxane polymer swelling agent (e)(ii) having a zero-shear viscosity of less than or equal to (≤) 15,000 mPa.s at 25oC for a suitable period of time. In this embodiment the organopolysiloxane polymer swelling agent (e)(ii) is preferably neat or unadulterated. The suitable period of time may be at least 1 hour, alternatively at least 12 hours, alternatively at least 24 hours, alternatively at least 48 hours. This enables said organopolysiloxane polymer swelling agent (e)(ii) to penetrate and swell said preformed silicone elastomeric particulates (e)(i) to form component (e). This equates to step (2) of the method above. Subsequently the resulting mixture of swollen (e)(i) and residual (e)(ii) are added to the hydrosilylation curable silicone rubber coating composition or a part thereof, typically the Part B composition which comprises step (3) in the above method. As indicated previously, steps (1), (2) and optionally (3) can alternatively be carried out simultaneously. In this embodiment component (e) may be prepared by swelling the preformed silicone elastomeric particulates (e)(i) in the hydrosilylation curable silicone rubber coating composition containing component (e)(ii) or more often in a part composition of the hydrosilylation curable silicone rubber coating composition when being stored in multiple parts prior to use. In such an embodiment swelling can occur throughout the period during which preformed silicone elastomeric particulates (e)(i) are stored in the presence of component (e)(ii) in said part of the hydrosilylation curable silicone rubber coating composition containing component (e)(ii). When the organopolysiloxane polymer swelling agent (e)(ii) is initially stored in one part of a two- part composition, e.g., in a Part B composition it may be present in an amount of from 2.wt. % to 10 wt. % of the part B composition prior to mixing in a 1 : 1 weight ratio with Part A. Typically, the part B composition is used as it does not contain any catalyst the preformed silicone elastomeric particulates may contain Si-H groups which could initiate some curing during storage if mixed with the catalyst. In this embodiment, organopolysiloxane polymer swelling agent (e)(ii) may comprise or consist of component (c) the cross-linker or at least 1.0 wt. % of component (a) or a mixture of both component (c) and said at least 1.0 wt. % of component (a) or may be an organopolysiloxane polymer plasticiser. The preformed silicone elastomeric particulates (e)(i) are swelled after being added to the relevant part of the composition containing component (e)(ii). For example, the swelling agent may be introduced into the Part B composition (described in more detail later) and the preformed silicone elastomeric particulates (e)(i) are swollen for a predetermined period of time in the Part B composition, after which the parts A and B compositions are mixed together and the hydrosilylation curable silicone rubber coating composition is cured. Typically, preformed silicone elastomeric particulates (e)(i) will remain swollen by the presence of organopolysiloxane polymer swelling agent (e)(ii) throughout the lifetime of its use, even after cure. In one embodiment herein when it is known that component (e)(i) was derived from hydrosilylation cured silicone rubber, the resulting preformed silicone elastomeric particulates will contain residual Si-H that can react into the matrix during cure and cause weak points in the final article that leads to fracture at lower elongations. In such a case simultaneous with or prior to the penetration and swelling step the component (e)(i) particulates may be treated with a monofunctional capping agent (e)(iii) which may, for example, be a polydiorganosiloxane having one unsaturated group per molecule i.e., having one alkenyl group per molecule. Indeed, the monofunctional capping agent (e)(iii) may also function as the swelling agent by interacting with the residual Si-H groups while swelling the preformed silicone elastomeric particulates. Conversely, in cases where there is residual vinyl present in the preformed silicone elastomeric particulates, it may be beneficial to treat the particulate the swelling agent may also include a mono-Si-H functional capping agent(e)(iii). When capping, a non-reactive component (e)(ii) is added mostly to improve the efficiency of the capping reaction by exposing trapped Si-H in the particulate interior and the monofunctional capping agent is typically a monoalkenyl-functional monomer or oligomer or a monoalkynyl- functional monomer or oligomer, for example a linear or branched alkene or alkyne comprising from 2 to 20 carbons, alternatively 6 to 15 carbons having one reactive alkene or alkyne group per molecule such as 1-dodecene. Other compounds having a solitary alkene or alkyne group may alternatively be utilised as capping agent (e)(iii) providing the alkene or alkyne group is available for interaction with the Si-H of the hydrosilylation cured preformed silicone elastomeric particulates. For example, alkylvinyl ethers such as ethyl vinyl ether and dodecylvinyl ether, monovinyl polydimethylsiloxane, acrylates and methacrylates, such as methyl methacrylate, cyclohexyl methacrylate, 2-ethylhexyl acrylate, iso- octyl acrylate, stearyl methacrylate, trimethoxysilylpropyl methacrylate, isobornyl methacrylate, and hexafluoroisopropyl methacrylate; polyalkylene glycols comprising one alkenyl and / or alkynyl group such as monovinyl polyethylene glycol, monovinyl polypropylene glycol and monovinyl polyethylenepolypropylene glycol copolymers; monoallyloxy polyalkylene glycols such as monoallyloxy polyethylene glycol and monoallyloxy polypropylene glycol and monoallyloxy polyethylenepolypropylene glycol copolymers; styrene, a-methyl styrene, acrylic acid, and hexafluoroisopropyl methacrylate. When the preformed silicone elastomeric particulates (e)(i) were condensation cured then the particulates may be capped with compounds having a singular reactive group which will react with the reactive groups in the preformed silicone elastomeric particulates for example alkoxysilanes such as n-octyltrimethoxysilane, n-undecyltrimethoxysilane, methyltrimethoxysilane, isobutyltrimethoxysilane, n-propyldimethylmethoxysilane, n-butyltrimethoxysilane, ethyltrimethoxysilane, n-octylmethyldimethoxysilane and n-propylmethyldimethoxysilane; Alkenyl trialkoxysilanes such as vinyltrimethoxysilane, allyl trimethoxysilane, hexenyl trimethoxysilane, and undecylenyl trimethoxysilane; Alkenyldialkoxyalkylsilanes such as vinyldimethoxymethylsilane, allyl dimethoxymethylsilane, hexenyl dimethoxymethylsilane and undecylenyl dimethoxymethylsilane; Alkenylalkoxydialkylsilanes such as vinylmethoxydimethylsilane, allyl methoxydimethylsilane, hexenyl methoxydimethylsilane and undecylenyl methoxydimethylsilane; glycidoxyalkyltrialkoxysilanes such as glycidoxypropyltrimethoxysilane and glycidoxymethyltrimethoxysilane; glycidoxyalkyldialkoxyalkylsilanes such as glycidoxypropyldimethoxymethylsilane, glycidoxymethyldimethoxymethylsilane; and glycidoxyalkylalkoxydialkylsilanes such as glycidoxypropylmethoxydimethylsilane, glycidoxymethyl methoxydimethylsilane and N-(2-aminoethyl)-3-aminopropyltrimethoxysilane. These monofunctional capping agents (e)(iii) were intended to function as network modifying additives to “tune” the interface between the hydrosilylation curable silicone rubber coating composition and preformed silicone elastomeric particulate phases and thus the tensile properties by promoting physical entanglement between said hydrosilylation curable silicone rubber coating composition and particulate phases. The above capping step may also be done simultaneously with steps (1), (2) and optionally step (3). Once preformed silicone elastomeric particulates have been capped, it can be mixed into the hydrosilylation curable silicone rubber coating composition. Generally, it is easier to first mix the capped preformed silicone elastomeric particulates into one part of the hydrosilylation curable silicone rubber coating composition e.g., Part B as mentioned above. In such situations the swelling step may take place during capping and / or after addition of the capped preformed silicone elastomeric particulates into the hydrosilylation curable silicone rubber coating composition. Swelled component (e) Typically said component (e), after component (e)(i) has been swollen by component (e)(ii) and optionally passivated by capping agent (e)(iii) for a predetermined time, is present in an amount of from 5 wt. % to 80 wt. % of the hydrosilylation reaction curable silicone rubber coating composition, alternatively is present in an amount of from 5 wt. % to 50 wt. % of the composition, alternatively in an amount of from 7.5 wt. % to 35 wt. % of the composition, alternatively in an amount of from 7.5 wt. % to 30 wt. % of the composition, alternatively in an amount of from 9.0 wt. % to 25 wt. % of the composition. In addition to components (e)(i) and (e)(ii) the hydrosilylation curable silicone rubber coating composition utilised to make the coated fabric article, e.g., airbag or an airbag fabric article comprises the following components: Component (a) Component (a) of the hydrosilylation curable silicone rubber coating composition utilised to make the coated fabric article e.g., an airbag or an airbag fabric article coated with a cured product thereof is one or more organopolysiloxane polymers having a viscosity of between 100 and 200,000mPa.s inclusive at 25 ºC, and at least two unsaturated groups per molecule, which unsaturated groups are selected from alkenyl and / or alkynyl groups. Each organopolysiloxane polymer of component (a) comprises multiple siloxy units, of formula (I): R’aSiO(4-a) / 2 (I) The subscript “a” is 0, 1, 2 or 3. Siloxy units may be described by a shorthand (abbreviated) nomenclature, namely - "M," "D," "T," and "Q", when R’ is as described above, alternatively an alkyl group, typically a methyl group. The M unit corresponds to a siloxy unit where a = 3, that is R’3SiO1 / 2; the D unit corresponds to a siloxy unit where a = 2, namely R’2SiO2 / 2; the T unit corresponds to a siloxy unit where a = 1, namely R’1SiO3 / 2; the Q unit corresponds to a siloxy unit where a = 0, namely SiO4 / 2. The organopolysiloxane polymer of component (a) is substantially linear but may contain a proportion of branching due to the presence of T units (as previously described) within the molecule, hence the average value of a in structure (I) is about 2. The unsaturated groups of component (a) may be positioned either terminally or pendently on the organopolysiloxane polymer, or in both locations. The unsaturated groups of component (a) may be alkenyl groups or alkynyl groups as described above. Each alkenyl group, when present, may comprise for example from 2 to 30, alternatively 2 to 24, alternatively 2 to 20, alternatively 2 to 12, alternatively 2 to 10, and alternatively 2 to 6 carbon atoms. When present the alkenyl groups may be exemplified by, but not limited to, vinyl, allyl, methallyl, propenyl, and hexenyl and cyclohexenyl groups. Each alkynyl group, when present, may also have 2 to 30, alternatively 2 to 24, alternatively 2 to 20, alternatively 2 to 12, alternatively 2 to 10, and alternatively 2 to 6 carbon atoms. Examples of alkynyl groups may be exemplified by, but not limited to, ethynyl, propynyl, and butynyl groups. Preferred examples of the unsaturated groups of component (a) include vinyl, propenyl, isopropenyl, butenyl, allyl, and 5-hexenyl. In formula (I), each R’, other than the unsaturated groups described above, is independently selected from an aliphatic hydrocarbyl group, a substituted aliphatic hydrocarbyl group, an aromatic group or a substituted aromatic group. Each aliphatic hydrocarbyl group may be exemplified by, but not limited to, alkyl groups having from 1 to 20 carbons per group, alternatively 1 to 15 carbons per group, alternatively 1 to 12 carbons per group, alternatively 1 to 10 carbons per group, alternatively 1 to 6 carbons per group or cycloalkyl groups such as cyclohexyl. Specific examples of alkyl groups may include methyl, ethyl, propyl, pentyl, octyl, undecyl, and octadecyl groups, alternatively methyl and ethyl groups. Substituted aliphatic hydrocarbyl group are preferably non-halogenated substituted alkyl groups. The aliphatic non-halogenated organyl groups are exemplified by, but not limited to alkyl groups as described above with a substituted group such as suitable nitrogen containing groups such as amido groups, imido groups; oxygen containing groups such as polyoxyalkylene groups, carbonyl groups, alkoxy groups and hydroxyl groups. Further organyl groups may include sulfur containing groups, phosphorus containing groups, boron containing groups. Examples of aromatic groups or substituted aromatic groups are phenyl groups and substituted phenyl groups with substituted groups as described above. Component (a) may, for example, be selected from polydimethylsiloxanes, alkylmethylpolysiloxanes, alkylarylpolysiloxanes or copolymers thereof (where reference to alkyl means any suitable alkyl group, alternatively an alkyl group having two or more carbons) providing each polymer has a viscosity of organopolysiloxane polymer (a) should be between 100 and 200,000mPa.s inclusive at 25 ºC, Hence component (a) may, for the sake of example, be: a dialkylalkenyl terminated polydimethylsiloxane, e.g., dimethylvinyl terminated polydimethylsiloxane; a dialkylalkenyl terminated dimethylmethylphenylsiloxane, e.g., dimethylvinyl terminated dimethylmethylphenylsiloxane; a trialkyl terminated dimethylmethylvinyl polysiloxane; a dialkylvinyl terminated dimethylmethylvinyl polysiloxane copolymer; a dialkylvinyl terminated methylphenylpolysiloxane, a dialkylalkenyl terminated methylvinylmethylphenylsiloxane; a dialkylalkenyl terminated methylvinyldiphenylsiloxane; a dialkylalkenyl terminated methylvinyl methylphenyl dimethylsiloxane; a trimethyl terminated methylvinyl methylphenylsiloxane; a trimethyl terminated methylvinyl diphenylsiloxane; or a trimethyl terminated methylvinyl methylphenyl dimethylsiloxane. In each case component (a) The viscosity of organopolysiloxane polymer (a) should be between 100 and 200,000mPa.s inclusive at 25 ºC, alternatively from 1000 to 150,000mPa.s at 25 ºC, alternatively, from 1000mPa.s to 125,000mPa.s, alternatively from 1000mPa.s to 100,000mPa.s at 25 ºC. Unless otherwise indicated all viscosity measurement given are zero-shear viscosity (ηo) values, obtained by extrapolating to zero the value taken at low shear rates (or simply taking an average of values) in the limit where the viscosity-shear rate curve is rate-independent, which is a test-method independent value provided a suitable, properly operating rheometer is used. For example, the zero- shear viscosity of a substance at 25 °C may be obtained by using commercial rheometers such as an Anton-Parr MCR-301 rheometer or a TA Instruments AR-2000 rheometer equipped with cone-and- plate fixtures of suitable diameter to generate adequate torque signal at a series of low shear rates, such as 0.01 s-1, 0.1 s-1and 1.0 s-1while not exceeding the torque limits of the transducer. Alternatively, the viscosity measurements may be obtained using an ARES-G2 rotational rheometer, commercially available from TA Instruments using a steady rate sweep from 0.1 to 10 s-1on a 25 mm cone and plate. If the zero-shear plateau region cannot be observed at shear rates accessible to the rheometer or viscometer, we report the viscosity measured at a standard shear rate of 0.1 s-1at 25 °C. Typically, the alkenyl and / or alkynyl content, e.g., vinyl content of the polymer is from 0.01 to 3 wt. % for each organopolysiloxane polymer containing at least two silicon-bonded alkenyl groups per molecule of component (a), alternatively from 0.01 to 2.5 wt. % of component (a), alternatively from 0.001 to 2.0 wt. %, alternatively from 0.01 to 1.5 wt. % of component (a) of the or each organopolysiloxane polymer containing at least two unsaturated groups per molecule, which unsaturated groups are selected from alkenyl and / or alkynyl groups per molecule of component (a). The alkenyl / alkynyl content of component (a) is determined using quantitative infra-red analysis in accordance with ASTM E168. Component (a) may be present in the hydrosilylation curable silicone rubber coating composition in an amount of from 40 wt. % to about 80 wt. % of the hydrosilylation curable silicone rubber coating composition, alternatively from 45 to 80 wt. % of the composition, alternatively from 50 to 80 wt. % of the hydrosilylation curable silicone rubber coating composition. Typically, component (a) is present in an amount which is the difference between 100 wt. % and the cumulative wt. % of the other components / ingredients of the composition. Component (b) Component (b) of the hydrosilylation curable silicone rubber coating composition utilised to make the coated fabric article e.g., an airbag or an airbag fabric article coated with a cured product thereof is optional and is a reinforcing filler comprising fumed silica, precipitated silica or a mixture thereof but may also comprise calcium carbonate, typically precipitated calcium carbonate. The reinforcing filler is provided to reinforce the physical properties of the elastomers provided when the composition is cured. Finely divided forms of silica are preferred. Reinforcing fillers (b) e.g., silica fillers having a relatively high surface area, typically at least 50 m² / g (BET method in accordance with ISO 9277: 2010) are utilized. For example, fillers, (e.g., fumed silica) having surface areas of from 50-450m2 / g, alternatively, 50 – 400m2 / g m2 / g, alternatively from 50 to 300 m² / g, alternatively 100 - 300m2 / g (BET method in accordance with ISO 9277: 2010) are typically used. Typically, the reinforcing filler(s) (b) is / are naturally hydrophilic (e.g., untreated) silica fillers, and are therefore treated with a treating agent to render it / them hydrophobic. These surface modified reinforcing fillers (b) do not clump and can be homogeneously incorporated into organopolysiloxane polymer (a), described below, as the surface treatment makes the fillers easily wetted by organopolysiloxane polymer (a). Typically, the reinforcing filler (b) are surface treated with any low molecular weight organosilicon compounds disclosed in the art applicable to prevent creping of organosiloxane compositions during processing. For example, organosilanes, polydiorganosiloxanes, or organosilazanes e.g., hexaalkyl disilazane, short chain siloxane diols or fatty acids or fatty acid esters such as stearates may be used to render the filler(s) hydrophobic and therefore easier to handle and obtain a homogeneous mixture with the other ingredients. Specific examples include but are not restricted to silanol terminated trifluoropropylmethyl siloxane, silanol terminated vinylmethylsiloxane, tetramethyldi(trifluoropropyl)disilazane, tetramethyldivinyl disilazane, hexamethyl disilazane (HMDZ), silanol terminated MePh siloxane, liquid hydroxyl-terminated polydiorganosiloxane containing an average from 2 to 20 repeating units of diorganosiloxane in each molecule, hexaorganodisiloxane, hexaorganodisilazane. A small amount of water can be added together with the silica treating agent(s) as a processing aid. The reinforcing silica fillers (b) may be pre-treated prior to introduction into the hydrosilylation curable silicone rubber coating composition or may be treated in situ (i.e., in the presence of at least a portion of the other ingredients of the hydrosilylation curable silicone rubber coating composition herein by blending these ingredients together at room temperature or above until the filler is completely treated. Typically, when present untreated reinforcing filler (b) is treated in situ with a treating agent in the presence of organopolysiloxane polymer (a) which results in the preparation of a silicone rubber base material which can subsequently be mixed with other ingredients. When present, the reinforcing filler (b) is present in the hydrosilylation curable silicone rubber coating composition utilised to make the airbag or an airbag fabric article coated with a cured product thereof in an amount of from 1.0 to 40wt. %. of the composition, alternatively of from 1 to 30wt. %. of the composition, alternatively of from 5.0 to 25wt. %. of the composition. Component (c) Component (c) of the hydrosilylation curable silicone rubber coating composition utilised to make the coated fabric article e.g., an airbag or an airbag fabric article coated with a cured product thereof functions as a cross-linker and is provided in the form of an organosilicon compound having an average of at least two or alternatively an average of at least three Si-H groups per molecule. Component (c) is typically linear, branched or a silicone resin. Component (c) normally contains three or more silicon-bonded hydrogen atoms so that the hydrogen atoms can react with the unsaturated groups (alkenyl and / or alkynyl groups) of component (a) and / or the rest of the composition to form a network structure therewith and thereby cure the composition. Some or all of Component (c) may alternatively have two silicon bonded hydrogen atoms per molecule. However, such a molecule is only used as the sole cross-linker when e.g., polymer (a) has greater than two unsaturated groups per molecule in which case a network can be produced during the cure process. Otherwise, when component (c) partially comprises, molecules having an average of two silicon bonded hydrogen atoms per molecule, said molecules may function as a chain extender. The molecular configuration of the organosilicon compound having at least two, alternatively at least three Si-H groups per molecule (c) is not specifically restricted, and it can be a silane or a straight chain, branched (a straight chain with some branching through the presence of T units) or cyclic polymer or be silicone resin based. All viscosities are measured at 25oC and are zero-shear measurements using the method described previously. Silicon-bonded organic groups used in component (c) may be exemplified by alkyl groups such as methyl, ethyl, propyl, n-butyl, t-butyl, pentyl, hexyl; aryl groups such as phenyl tolyl, xylyl, or similar aryl groups; 3-chloropropyl, 3,3,3-trifluoropropyl, or similar halogenated alkyl group, preferred alkyl groups having from 1 to 6 carbons, especially methyl ethyl or propyl groups or phenyl groups. Alternatively, the silicon-bonded organic groups used in component (c) are alkyl groups, alternatively methyl, ethyl or propyl groups. Examples of the organosilicon compound having at least two or alternatively at least three Si-H groups per molecule (c) include but are not limited to: (a’) trimethylsiloxy-terminated methylhydrogenpolysiloxane, (b’) trimethylsiloxy-terminated polydimethylsiloxane-methylhydrogensiloxane, (c’) dimethylhydrogensiloxy-terminated dimethylsiloxane-methylhydrogensiloxane copolymers, (d’) dimethylsiloxane-methylhydrogensiloxane cyclic copolymers, (e’) copolymers and / or silicon resins consisting of (CH3)2HSiO1 / 2 units, (CH3)3SiO1 / 2 units and SiO4 / 2 units, (f’) copolymers and / or silicone resins consisting of (CH3)2HSiO1 / 2 units and SiO4 / 2 units, (g’) Methylhydrogensiloxane cyclic homopolymers having between 3 and 10 silicon atoms per molecule; alternatively, component (c), the cross-linker, may be a filler, e.g., silica treated with one of the above, and mixtures thereof. In one embodiment the Component (c) is selected from a methylhydrogenpolysiloxane capped at both molecular terminals with trimethylsiloxy groups; a copolymer of a methylhydrogensiloxane and a dimethylsiloxane capped at both molecular terminals with trimethylsiloxy groups; dimethylsiloxane capped at both molecular terminals with dimethylhydrogensiloxy groups; a copolymer of a methylhydrogensiloxane and a dimethylsiloxane capped at both molecular terminals with dimethylhydrogensiloxy groups. The cross-linker (c) is generally present in the hydrosilylation reaction curable silicone rubber coating composition such that the molar ratio of the silicon-bonded hydrogen atoms in component (c) to the total unsaturated groups selected from alkenyl and / or alkynyl groups in the composition is from 0.5:1 to 20:1. When this ratio is less than 0.5:1, a well-cured composition will not be obtained. When the ratio exceeds 20:1, there is a tendency for the hardness of the cured hydrosilylation curable silicone rubber coating composition to increase when heated. The molar ratio of silicon-bonded hydrogen atoms of component (c) to total unsaturated groups selected from alkenyl and / or alkynyl groups in the organopolysiloxane (a) is preferably at least 0.8:1 and can be up to 8:1 or 10:1. Most preferably the molar ratio of Si-H groups to aliphatically unsaturated groups is in the range from 1.1:1 to 5:1. The silicon-bonded hydrogen (Si-H) content of component (c) is determined using quantitative infra-red analysis in accordance with ASTM E168. In the present instance the silicon-bonded hydrogen to alkenyl (vinyl) and / or alkynyl ratio is important when relying on a hydrosilylation cure process. Generally, this is determined by calculating the total weight % of alkenyl groups in the hydrosilylation curable silicone rubber coating composition e.g., vinyl [V] and the total weight % of silicon bonded hydrogen [H] in the composition and given the molecular weight of hydrogen is 1 and of vinyl is 27 the molar ratio of silicon bonded hydrogen to vinyl is 27[H] / [V]. Typically, dependent on the number of unsaturated groups in component (a) and the rest of the hydrosilylation curable silicone rubber coating composition as well as the number of Si-H groups in component (c), component (c) will be present in an amount of from 0.1 to 10 wt. % of the hydrosilylation curable silicone rubber coating composition, alternatively 0.1 to 7.5 wt. % of the hydrosilylation curable silicone rubber coating composition, alternatively 0.25 to 7.5wt. %, further alternatively from 0.25% to 5 wt. % of the hydrosilylation curable silicone rubber coating composition. (d) Hydrosilylation catalyst Component (d) of the hydrosilylation curable silicone rubber coating composition utilised to make the coated fabric article e.g., an airbag or an airbag fabric article coated with a cured product thereof, is a hydrosilylation catalyst comprising or consisting of a platinum group metal or a compound thereof. These are usually selected from catalysts of the platinum group of metals (platinum, ruthenium, osmium, rhodium, iridium and palladium), or a compound of one or more of such metals. Alternatively, platinum and rhodium compounds are preferred due to the high activity level of these catalysts in hydrosilylation reactions, with platinum compounds most preferred. In a hydrosilylation (or addition) reaction, a hydrosilylation catalyst such as component (d) herein catalyses the reaction between an unsaturated group, usually an alkenyl group e.g., vinyl with Si-H groups. The hydrosilylation catalyst of component (d) can be a platinum group metal, a platinum group metal deposited on a carrier, such as activated carbon, metal oxides, such as silicon dioxide, silica gel or powdered charcoal, or a compound or complex of a platinum group metal. Preferably the platinum group metal is platinum. Examples of preferred hydrosilylation catalysts of component (d) are platinum based catalysts, for example, platinum black, platinum oxide (Adams catalyst), platinum on various solid supports, chloroplatinic acids, e.g., hexachloroplatinic acid (Pt oxidation state IV) (Speier catalyst), chloroplatinic acid in solutions of alcohols e.g., isooctanol or amyl alcohol (Lamoreaux catalyst), and complexes of chloroplatinic acid with ethylenically unsaturated compounds such as olefins and organosiloxanes containing ethylenically unsaturated silicon-bonded hydrocarbon groups, e.g., tetra- vinyl-tetramethylcyclotetrasiloxane-platinum complex (Ashby catalyst). Soluble platinum compounds that can be used include, for example, the platinum-olefin complexes of the formulae (PtCl2.(olefin)2and H(PtCl3.olefin), preference being given in this context to the use of alkenes having 2 to 8 carbon atoms, such as ethylene, propylene, isomers of butene and of octene, or cycloalkanes having 5 to 7 carbon atoms, such as cyclopentene, cyclohexene, and cycloheptene. Other soluble platinum catalysts are, for the sake of example a platinum-cyclopropane complex of the formula (PtCl2C3H6)2, the reaction products of hexachloroplatinic acid with alcohols, ethers, and aldehydes or mixtures thereof, or the reaction product of hexachloroplatinic acid and / or its conversion products with vinyl-containing siloxanes such as methylvinylcyclotetrasiloxane in the presence of sodium bicarbonate in ethanolic solution. Platinum catalysts with phosphorus, sulfur, and amine ligands can be used as well, e.g., (Ph3P)2PtCl2; and complexes of platinum with vinylsiloxanes, such as sym-divinyltetramethyldisiloxane (Karstedt’s catalyst). Hence, specific examples of suitable platinum-based catalysts of component (d) include: (i) complexes of chloroplatinic acid with organosiloxanes containing ethylenically unsaturated hydrocarbon groups are described in US 3,419,593; (ii) chloroplatinic acid, either in hexahydrate form or anhydrous form; (iii) a platinum-containing catalyst which is obtained by a method comprising reacting chloroplatinic acid with an aliphatically unsaturated organosilicon compound, such as divinyltetramethyldisiloxane; (iv) alkene-platinum-silyl complexes as described in US Pat. No.6,605,734 such as (COD)Pt(SiMeCl2)2 where “COD” is 1,5-cyclooctadiene; and / or (v) Karstedt's catalyst, a platinum divinyl tetramethyl disiloxane complex typically containing about 1 wt. % of platinum typically in a vinyl siloxane polymer. Solvents such as toluene and the like organic solvents have been used historically as alternatives but the use of vinyl siloxane polymers by far the preferred choice. These are described in US3,715,334 and US3,814,730. In one preferred embodiment component (d) may be selected from co-ordination compounds of platinum. In one embodiment hexachloroplatinic acid and its conversion products with vinyl-containing siloxanes, Karstedt's catalysts and Speier catalysts are preferred. In one embodiment the catalyst may be encapsulated during storage, especially in the case of one-part compositions to prevent premature cure. The catalytic amount of the hydrosilylation catalyst is generally between 0.01 ppm, and 10,000 parts by weight of platinum-group metal, per million parts (ppm), based on the weight of the hydrosilylation curable silicone rubber coating composition; alternatively, between 0.1 and 7500ppm; alternatively, between 100 and 75000 ppm, and alternatively between 500 and 6,000 ppm. The ranges may relate solely to the metal content within the catalyst or to the catalyst altogether (including its ligands) as specified, but typically these ranges relate solely to the metal content within the catalyst. The catalyst may be added as a single species or as a mixture of two or more different species. Typically, dependent on the form / concentration in which the catalyst is provided e.g., in a polymer or solvent, the amount of component (d) present will be within the range of from 0.001 to 3.0 wt. % of the hydrosilylation curable silicone rubber coating composition, alternatively from 0.001 to 1.5 wt. % of the composition, alternatively from 0.01–1.5 wt. %, alternatively 0.01 to 0.1.0 wt. %, of the hydrosilylation curable silicone rubber coating composition. (f) Adhesion Promoter Component (f) of the hydrosilylation curable silicone rubber coating composition utilised to make the coated fabric article e.g., an airbag or an airbag fabric article coated with a cured product thereof is any suitable adhesion promoter. The adhesion promoter may for example be an alkoxysilane coupling agent, Examples of adhesion promoters which may be incorporated in moisture curable compositions according to the invention include alkoxysilanes such as aminoalkylalkoxysilanes, for example 3-aminopropyltriethoxysilane, epoxyalkylalkoxysilanes, for example, 3- glycidoxypropyltrimethoxysilane and, mercapto-alkylalkoxysilanes, (trimethoxysillyl)ethane and (meth)acryloxy type adhesion promoters such as methacryloxypropyltrimethoxysilane and reaction products of ethylenediamine with silylacrylates. Isocyanurates containing silicon groups such as 1, 3, 5-tris(trialkoxysilylalkyl) isocyanurates may additionally be used. The adhesion promoter may be present in an amount of from 0.1 to 5.0 wt. % of the hydrosilylation reaction curable silicone rubber coating composition, alternatively from 0.1 to 3.5 wt. % of the composition alternatively from 0.1 to 2.5 wt. % of the composition, alternatively from 0.1 to 2.25 wt. % of the composition alternatively from 0.2 to 2.0 wt. % of the composition. Further suitable adhesion promoters are reaction products of epoxyalkylalkoxysilanes such as 3- glycidoxypropyltrimethoxysilane with amino-substituted alkoxysilanes such as 3- aminopropyltrimethoxysilane and optionally with alkylalkoxysilanes such as methyltrimethoxysilane. In one alternative the adhesion promoter may be a combination of an alkoxysilane coupling agent with an organometallic adhesion catalyst such as zirconium (IV) tetraacetyl acetonate, (sometimes referred to as zirconium AcAc4), or aluminium (III) triacetyl acetonate, (sometimes referred to as aluminium AcAc3). Typically, such a catalyst is introduced in an amount of from 0.05 - 0.3 wt.% of the composition. Component (g) (Optional) The optional one or more silicone resins of component (g) in the hydrosilylation curable silicone rubber coating composition utilised to make the coated fabric article e.g., an airbag or an airbag fabric article coated with a cured product thereof are silicone resins containing unsaturated groups selected from alkenyl groups, alkynyl groups or a mixture of alkenyl groups and alkynyl groups, selected from T silicone resins (silsesquioxanes), DT silicone resins, MQ silicone resins, MDT silicone resins, MTQ silicone resins, QDT silicone resins or mixtures thereof. Such resins of component (g) using the MDTQ notation comprise Q type (SiO4 / 2) siloxane units T type (R21SiO3 / 2) siloxane units; D type (R21SiO3 / 2) siloxane units and R2₃SiO1 / 2 (M) siloxane units as indicated. These resins can be classified into two broad categories: silsesquioxanes and silicates. Silsesquioxanes, or T resins, are predominantly comprised of T units and can be synthesized by the hydrolysis and condensation of alkoxysilanes, chlorosilanes, or mixtures thereof. Silicates, or MQ resins, are predominantly comprised of M and Q units and can be synthesized through the hydrolysis and condensation of alkoxysilanes and chlorosilanes. Alternatively, MQ resins can be synthesized through the polymerization of aqueous alkali silicates in the presence of acid followed by reaction with triorgano alkoxysilanes, triorgano chlorosilanes, hexaorganodisiloxanes or mixtures thereof. Preferably, component (g) is one or more MQ resins. Typically, the MQ resins of component (g), when present, comprise SiO4 / 2(Q) siloxane units and R2₃SiO1 / 2(M) siloxane units wherein each R2 may be the same or different and denotes a monovalent group selected from hydrocarbon groups, having from 1 to 20 carbon atoms and, alternatively from 1 to 12 carbon atoms. Examples of suitable R2groups include alkyl groups, such as methyl, ethyl, propyl, pentyl, octyl, undecyl and octadecyl; cycloaliphatic groups, such as cyclohexyl; alkenyl groups, having from 2 to 12 carbons, such as vinyl, propenyl, butenyl, pentenyl, hexenyl, and the like; alkynyl groups selected from ethynyl, propynyl, butynyl, pentynyl or hexynyl and the like; aryl groups such as phenyl, tolyl, xylyl, benzyl, alpha-methyl styryl and 2-phenylethyl; alternatively R2groups are vinyl, methyl, ethyl or phenyl groups, e.g., examples of preferred R2₃SiO1 / 2(M) siloxane units include Me₃SiO1 / 2, PhMe₂SiO1 / 2, ViMe₂SiO1 / 2and Ph₂MeSiO1 / 2,where Me hereinafter denotes methyl, Vi is vinyl and Ph hereinafter denotes phenyl. T silicone resins may alternatively be referred to as silsesquioxanes. The silicone resin can be a single silicone resin or a mixture comprising two or more different silicone resins, each as described above. Typically, they are MQ resins comprising ViMe₂SiO1 / 2 In combination with Me₃SiO1 / 2, and / or PhMe₂SiO1 / 2groups. Additionally, the silicone resin is an MQ resin which may contain residual OZ5, where Z5can represent hydrogen or alkyl groups. O Z5groups remain on the Q components after synthesis of silicone MQ resins indicative of incomplete condensation during the reaction to produce the MQ resin providing the OZ content meets the above hydroxyl per mole Si requirements. Residual O Z5is inherent to the processes and reactions utilized to make MQ resins. The MQ resin may also undergo a subsequent silylation reaction to further minimize residual O Z5. The silicone resin (g), when present, is typically delivered in a hydrocarbon or silicone solvent, free from solvent the silicone resin is typically a solid but preferably herein the silicone resin (g) is delivered in a silicone solvent such as a non-functional polydimethylsiloxane or a polydimethylsiloxane comprising two or more alkenyl groups per molecule, such as for example component (a) herein. For example, any suitable MQ resin may be utilized as component (g), if required. The molar ratio of M siloxane units to Q siloxane units has a value of from 0.5:1 to 1.2:1, alternatively 0.6:1 to 1.1:1, alternatively 0.8:1 to 1.1:1, alternatively 0.9:1 to 1.1:1. In one embodiment MQ resin (e) includes a resinous portion wherein the M units are bonded to SiO4 / 2 siloxane units (i.e., Q units) and each of Q units is bonded to at least one other SiO4 / 2 siloxane unit. The molar ratio of M units to Q units is from 0.3 : 1 to 1.2 : 1, alternatively 0.4:1 to 1.1:1, alternatively 0.5:1 to 1:1, alternatively 0.6:1 to 0.9:1. Such an MQ resin suitable as component (g) may have a number-average molecular weight (Mn) of from 2000 to 50,000g / mol, alternatively from 3,000 to 30,000 g / mol. In one embodiment the silicone resin may be described in the terms of a molar fraction as an MQ silicone resin having the formula: (R43SiO1 / 2)u(SiO4 / 2)v wherein R4is a C1to C10hydrocarbon group free of aliphatic unsaturation, u is from 0.3 to 0.6, alternatively 0.37 to 0.52, v is from 0.4 to 0.7, alternatively 0.48 to 0.63, and the value of u + v is 1.0. Methods of preparing silicone resins are well known in the art. For example, they may be made by treating a resin copolymer produced by a silica hydrosol capping process with an alkyl and / or alkenyl containing end-blocking agent. This preferably includes reacting a silica hydrosol under acidic conditions with a hydrolysable triorganosilane such as trimethylchlorosilane, a siloxane such as hexamethyldisiloxane, and combinations thereof, and then recovering a copolymer having M (R3SiO1 / 2) units and Q (SiO4 / 2) units including 0.07 to 0.2 moles hydroxyl per mole of silicon (Si). The copolymer may be further reacted with an end-blocking agent including saturated organic groups to achieve the less than 0.06 moles hydroxyl per mole Si. Suitable end-blocking agents include silazanes, siloxanes, silanes, and combinations thereof. When present, component (g) may be present in the hydrosilylation curable silicone rubber coating composition in an amount of from 1 - 60wt. %, alternatively 1 - 40wt. %, and is preferably in the form of an MQ resin. Methods of preparing silicone resins are well known in the art. For example, they may be made by treating a resin copolymer produced by a silica hydrosol capping process with an alkyl and / or alkenyl containing end-blocking agent. This preferably includes reacting a silica hydrosol under acidic conditions with a hydrolysable triorganosilane such as trimethylchlorosilane, a siloxane such as hexamethyldisiloxane, and combinations thereof, and then recovering a copolymer having M (R3SiO1 / 2) units and Q (SiO4 / 2) units including 0.07 to 0.2 moles hydroxyl per mole of silicon (Si). The copolymer may be further reacted with an end-blocking agent including saturated organic groups to achieve the less than 0.06 moles hydroxyl per mole Si. Suitable end-blocking agents include silazanes, siloxanes, silanes, and combinations thereof. Preferably, when component (b) is not present, component (g) is present to reinforce the coating. In such cases when (b) is absent and (g) is present the silicone resin (g) comprises one or more unsaturated groups e.g., vinyl groups, alternatively silicone resin (g) is a vinylated MQ resin. Preferably component (b) or component (g) is present or a mixture of components (b) and (g) are present in the composition. Components (a), (c), and (g) invariably consist of a mixture of macromolecular species with different degrees of polymerization and therefore of different molecular weights. There are different types of average polymer molecular weight, which can be measured in different experiments. The two most important are the number average molecular weight (Mn) and the weight average molecular weight (Mw). The Mn and Mw of a silicone polymer and / or resin can be determined by Gel permeation chromatography (GPC) using polystyrene calibration standards. This technique is standard and yields Mw, Mn and polydispersity index (PI). The degree of polymerisation (DP) = Mn / Mu where Mn is the coming from the GPC measurement and Mu is the molecular weight of a monomer unit. PI=Mw / Mn. The DP is linked to the viscosity of the polymer via Mw, the higher the DP, the higher the viscosity. The silicone resin typically has a weight-average molecular weight (Mw) of from 2,000 to 50,000 Daltons, alternatively from 3,000 to 40,000, alternatively from 3,000 to 30,000, alternatively from 4,000 to 30,000, alternatively 5,000 to 25,000 where the molecular weight is determined by gel permeation chromatography employing a triple detector system e.g., light-scattering detector, a refractive index detector, and / or a viscosity detector and polystyrene standards. Additional optional ingredients Additional optional ingredients may be present in the hydrosilylation curable silicone rubber coating composition utilised to make the coated fabric article e.g., an airbag or an airbag fabric article coated with a cured product thereof as hereinbefore described depending on the intended final use thereof. Examples of such optional ingredients include cure inhibitors, pot life extenders, flame retardants, lubricants, non-reinforcing fillers, pigments, dyes and / or colouring agents, bactericides, wetting agents, heat stabilizers, compression set additives, metal deactivators, plasticizers, and mixtures thereof. When the hydrosilylation curable silicone rubber coating composition as hereinbefore described is being cured via an addition / hydrosilylation reaction a cure inhibitor may be utilized to inhibit the cure of the composition. These cure inhibitors are utilized to prevent premature cure in storage and / or to obtain a longer working time or pot life of a hydrosilylation cured composition by retarding or suppressing the activity of the catalyst. Cure inhibitors of hydrosilylation catalysts (d), e.g., platinum metal-based catalysts are well known in the art and may include hydrazines, triazoles, phosphines, mercaptans, organic nitrogen compounds, acetylenic alcohols, silylated acetylenic alcohols, maleates, such as dibutyl maleate; fumarates, ethylenically or aromatically unsaturated amides, ethylenically unsaturated isocyanates, olefinic siloxanes, such as tetramethyltetravinylcyclotetrasiloxane; unsaturated hydrocarbon monoesters and diesters, conjugated ene-ynes, hydroperoxides, nitriles, and diaziridines. Alkenyl-substituted siloxanes as described in US 3,989,667 may be used, of which cyclic methylvinylsiloxanes are preferred. One class of known cure inhibitors of hydrosilylation catalysts, e.g., platinum catalysts (d) include the acetylenic compounds disclosed in US 3,445,420. Acetylenic alcohols such as 2-methyl-3-butyn-2-ol constitute a preferred class of cure inhibitors that will suppress the activity of a platinum-containing catalyst at 25 ºC. Compositions containing these cure inhibitors typically require heating at temperature of 70 ºC or above to cure at a practical rate. Examples of acetylenic alcohols and their derivatives include 1-ethynyl-1-cyclohexanol (ETCH), 2- methyl-3-butyn-2-ol, 3-butyn-1-ol, 3-methyl butynol 3-butyn-2-ol, propargyl alcohol, 2-phenyl-2- propyn-1-ol, 3,5-dimethyl-1-hexyn-3-ol, 1-ethynylcyclopentanol, 1-phenyl-2-propynol, 3-methyl-1- penten-4-yn-3-ol, and mixtures thereof. In one alternative the cure inhibitor is selected from one or more of 1-ethynyl-1-cyclohexanol (ETCH), tetramethyltetravinylcyclotetrasiloxane, 3-methyl butynol and / or dibutyl maleate. When present, cure inhibitor concentrations as low as 1 mole of cure inhibitor per mole of the metal of catalyst (d) will in some instances impart satisfactory storage stability and cure rate. In other instances, cure inhibitor concentrations of up to 500 moles of cure inhibitor per mole of the metal of catalyst (d) are required. The optimum concentration for a given cure inhibitor in a given hydrosilylation curable silicone rubber coating composition herein is readily determined by routine experimentation. Mixtures of the above may also be used. Dependent on the concentration and form in which the cure inhibitor selected is provided / available commercially, when present in the composition, the cure inhibitor is typically present in an amount of from 0.0001-10wt. %, alternatively 0.001-5%, cure inhibitor, alternatively 0.0125 to 5wt. % of the composition. Pot life extenders, such as triazole, may be used, but are not considered necessary in the scope of the present invention.

The hydrosilylation reaction curable silicone rubber coating composition can be any suitable combination of the above and total wt. % (weight %) of the composition is 100wt. %. When component (g) is present it is preferably an MQ type resin, alternatively a vinylated MQ resin. Furthermore, as indicated above in one alternative when component (b) is not present, component (g) is present to reinforce the coating. In such cases when (b) is absent and (g) is present the silicone resin (g) comprises one or more unsaturated groups e.g., vinyl groups, alternatively silicone resin (g) is a vinylated MQ resin. In one embodiment component (b) or component (g) is present or a mixture of components (b) and (g) are present in the composition. Typically, prior to use, the hydrosilylation curable silicone rubber coating composition utilised to make the coated fabric article, e.g., an airbag or an airbag fabric article, coated with a cured product thereof, is stored in two parts, Part A and Part B to keep components (c) cross-linker and (d) hydrosilylation cure catalyst apart to avoid premature cure. Typically, a Part A composition will comprise components (a) polymer, (b) reinforcing filler (when present) and (d) hydrosilylation cure catalyst and Part B will comprise components (a), (c) cross-linker, reinforcing filler (b) when present, and cure inhibitor, when present. Component (f) the adhesion promoter is typically stored in the Part B composition but may be stored in Part A or in Parts A and B. Component (g) can be added to either part, depending on its composition. Typically, component (g) is preferably added to at least part A when it contains unsaturated groups. Furthermore, component (e) is also introduced into the Part B composition. In one alternative, some of component (a) may have a low enough viscosity to function as component (e)(ii) when reactive in which case component (e)(i) and component (e)(ii) can be mixed together in a pre-mix or when some of the component (a) has a sufficiently low viscosity (i.e., less than 15,000mPa.s) component (e)(i) can be added directly into the Part B composition and be allowed to swell for a period of time as previously discussed. When component (e)(i) and component (e)(ii) are mixed together in a pre- mix, the pre-mix of component (e) may, once period of time allowed for swelling component (e)(i) has expired, be added directly into Part B or may be kept separately in a part C composition alone or with additional component (a) which part C is then mixed into the final composition simultaneously to when parts A and B are mixed together. Additives when present in a hydrosilylation curable silicone rubber coating composition utilised to make the coated fabric articles such as airbags or an airbag fabric articles, coated with a cured product thereof may be in either Part A or Part B, providing they do not negatively affect the properties of any other components present (e.g., catalyst inactivation). Part A and Part B of the hydrosilylation curable silicone coating composition described herein are mixed together shortly prior to use to initiate cure of the full composition into a silicone elastomeric material. The Part A and Part B compositions (and optional part C containing component (e)) can be designed to be mixed in any suitable weight ratio e.g., Part A : Part B may be mixed together in weight ratios of from 10:1 to 1:10, alternatively from 5:1 to 1:5, alternatively from 2:1 to 1:2, but most preferred is a weight ratio of 1:1. Ingredients in each of Part A and / or Part B may be mixed together individually or may be introduced into the composition in pre-prepared combinations for, e.g., ease of mixing the final composition. For Example, components (a) and (b) are often mixed together to form an LSR polymer base or masterbatch prior to addition with other ingredients. Similarly, component (e) may also be premixed with component (a), if desired. These may then be mixed with the other ingredients of Part B made directly or may be used to make pre-prepared concentrates commonly referred to in the industry as masterbatches. In this instance, for ease of mixing ingredients, one or more masterbatches may be utilized to successfully mix the ingredients to form Part A and / or Part B compositions. For example, a “fumed silica” masterbatch may be prepared. This is effectively an LSR silicone rubber base with silica treated in situ. Parts A and B of the hydrosilylation curable silicone rubber coating composition may be prepared by combining all of their respective components at ambient temperature. Any mixing techniques and devices described in the prior art can be used for this purpose. The particular device to be used will be determined by the viscosities of components and the final composition. Suitable mixers include but are not limited to paddle type mixers e.g., planetary mixers and kneader type mixers. Cooling of components during mixing may be desirable to avoid premature curing of the composition. Prior to use the respective Part A and Part B compositions are mixed together in the desired ratio. As part of the method herein the coating composition as hereinbefore described may be applied on to the substrate, for example a one-piece woven or flat fabric airbag substrate by any suitable known technique. These include spraying, gravure coating, bar coating, knife coating, e.g., coating by knife-over-roller, coating by knife-over-air; padding, dipping and screen-printing. The hydrosilylation curable silicone rubber coating composition can be applied onto one or both sides of a textile or fabric material substrate, e.g., an airbag fabric which is to be cut into pieces and sewn to assemble an airbag or may be applied onto a one-piece woven airbag. Curing of the hydrosilylation curable silicone coating composition of the present invention applied onto the woven fabric is typically conducted by heating the composition at a temperature of from 150 to 200°C for 45 seconds to 2 minutes which can be accomplished using a suitable oven or through drying tunnel of circulating hot-air ovens. Although it is not preferred, it is possible to apply the composition in multiple layers, which together have a pre-determined mean dry coat weight which can be measured in accordance with ISO 3801, It is also possible to apply onto the coating composition a further compatible coating, e.g., of a material providing e.g., low friction, if deemed necessary. Any suitable desired coat weight may be applied on the textile or fabric material such as an airbag, e.g., from 15 to 150 g / m2, alternatively from 15 to 100 g / m2, alternatively from 20 to 75 g / m2determined in accordance with ISO 3801. The thickness of coating layer ranges from of 20 to 80μm depending on the coating weight. When coated and cured on an uncoated airbag fabric at a representative coat weight to form a coated airbag article, the compositions of this invention demonstrate the essential performance feature of pressure retention upon deployment and / or protection of the bag, vehicle or occupants upon deployment against thermal, abrasive or impact-induced damage. When using physically recycled and / or reclaimed silicone elastomeric particulates as the preformed silicone elastomeric particulates herein, in addition to offering a commensurately lower carbon footprint, a silicone airbag coating by direct substitution of part of the hydrosilylation curable silicone rubber coating composition physically recycled and / or reclaimed silicone elastomeric particulates, the resulting coated fabric articles can be cheaper to make as they require less of the new hydrosilylation curable silicone rubber coating per coated fabric article. The textile or fabric substrate The textile or fabric substrate onto which the hydrosilylation curable silicone rubber coating composition is applied may be made from any suitable woven fabric, particularly a plain weave fabric, but can for example be a knitted or nonwoven fabric. The fabric or textile material may be made from synthetic fibres or blends of natural and synthetic fibres, for example polyamide fibres such as nylon-6, nylon-6,6 and nylon-4,6; polyester fibers such as polyethylene terephthalate and polybutylene terephthalate; polyimide, polyethylene, polypropylene, polyester-cotton, polyacrylonitrile fiber fabric, aramid fiber fabric, polyether imide fiber fabric, polysulfone fiber fabric, carbon fiber fabric, rayon fiber fabric and / or glass fibres. The textile or fabric substrate is typically treated on one side but may be treated on more than one side if desired, dependent on the intended final use. When treating an airbag, the airbag may be a one-piece woven airbag or may be flat fabric pieces which after coating are sewn together to provide sufficient mechanical strength. Such airbags are generally made from polyamide fiber fabric or polyester fiber fabric for applications requiring high strength, especially in the case of automotive one-piece woven airbags. Prior to coating with the hydrosilylation curable silicone rubber coating composition described herein, the woven fabric is preferably washed with water and dried. For use as an airbag fabric, the fabric should be sufficiently flexible to be able to be folded into relatively small volumes, but also sufficiently strong to withstand deployment at high speed, e.g., under the influence of an explosive charge. Polyamide and polyester fibres are particularly preferred for making airbag textiles; however, it can be difficult to get coatings to adhere to polyamide and polyester airbags, hence the need for adhesion promoters as described herein. The hydrosilylation curable silicone rubber coating composition utilised to make the coated fabric articles herein are designed to have particularly good adhesion and film forming properties immediately on contacting the substrate, so that film formation on the surface of the substrate being coated is uniform. Preferably they also have good penetration into the fabric used as the substrate and high levels of elongation. The airbag obtained by coating the substrate, e.g., an uncoated airbag fabric with the hydrosilylation curable silicone rubber coating composition described herein has at least one coating layer formed of a cured product from the hydrosilylation curable silicone rubber coating composition described herein. If necessary, however, one or more additional layers may be provided on the substrate. Such additional layers are applied typically for improving the tactile sensation of the surface of the treated article e.g., a coated woven fabric, for improving abrasion resistance of the surface and / or for improving the strength of the treated article. Whilst the additional coating layer(s) may be exemplified by a plastic film, a woven fabric, a non-woven fabric, or a coating layer formed of an elastic coating material other than the cured silicone rubber disclosed herein, preferably no additional layers are required or desired. Additionally, sections of the fabric coated by the cured silicone surface may be further over-coated or treated with a continuous, semi-continuous or dispersed topcoat, ink, sealant, or adhesive, depending on the requirements of the particular airbag design. This technology can be used in any suitable textile and / or fabric application but is particularly suited for airbags applications particularly in the automobile market but also for e.g., escape chutes from aircraft, sails, garments and the like. The substrates may be coated by the coatings and methods of this invention on any resultant side of the assembled article, or multiple sides. For instance, in One-piece-woven (OPW) airbags, the resultant airbag is typically coated on the surface(s) that eventually end up as the exposed upper and lower surfaces of the final article, both sides of which may optionally be further coated with a continuous, semi-continuous, or discrete topcoat to minimize any tendency of the contacting outer surfaces to stick together or “block”. In flat fabric airbag designs, the coated fabrics are typically assembled such that the coated surfaces end up being on the interior of the bag that forms after cutting, sewing and seam-sealing the periphery of the two pieces of fabric that form the article. In such designs, the uncoated outside faces may also be further coated in one or more areas to provide additional protection to the fabric, vehicle or occupants upon deployment. The coating formed by the curing of the hydrosilylation curable silicone rubber coating composition described herein has excellent adhesion to substrate used for airbag fabrics. The excellent adhesion durability to various fabrics provides the coated fabrics with long-term stability under heat and humidity aging conditions, thereby enhancing airbag reliability. Hence, the coating applied onto the substrate to make the coated fabric articles herein provides good mechanical strength, adhesion to woven fabrics as well as high elongation. Advantageously we are providing coated fabric articles, which are typically airbags or pieces of airbag fabric sewn together to make an airbag incorporating preformed silicone elastomeric particulates, obtained from post-industrial or post-consumer waste, As will be seen in the examples, a variety of preformed silicone elastomeric particulates may be incorporated into the compositions used to generate the coated fabric articles. Indeed, the coating compositions used to make the coated fabric articles, e.g., coated airbags and airbag material can contain physically recycled and / or reclaimed silicone elastomeric particulates from any of the following: condensation cured elastomers, peroxide cured elastomers and hydrosilylation cured elastomers including recycled airbag coatings, gaskets and seals, weatherproofing sealants, tire sealants, and refrigerant spacers. The physically recycled and / or reclaimed silicone elastomeric particulates have surprisingly found to be suitable for incorporation into a liquid silicone elastomer composition typically also containing a suitable adhesion promoter or mixture of adhesion promoters, to provide a lower carbon footprint curable elastomer composition that unexpectedly can be coated onto woven airbags to hold pressure and provide suitable mechanical properties that are known to be useful for airbag coating applications. The requirements and demands of the industry to reduce their carbon usage are necessitating sustainable materials to transition from being a “nice to have” feature to an increasingly important consideration in mobility & transportation markets. Hence there is provided herein the ability to manufacture airbag coatings which can be used to produce coated airbags and coated airbag materials containing interpenetrating silicone-silicone networks as a means of incorporating preformed silicone elastomeric particulates into airbag coatings whilst avoiding the previous problems of “flaking out” of the particulates in the past when merely encapsulated. This results in the provision of a lower carbon footprint alternatives for liquid silicone rubber (LSR) coated airbags and a suitable use for end of use silicone elastomers. Examples In the following examples, the compositions are defined in weight % (wt. %) unless otherwise stated and unless otherwise indicated all viscosity measurements given are zero-shear viscosity (ηo) values, obtained by extrapolating to zero the value taken at low shear rates (or simply taking an average of values) in the limit where the viscosity-shear rate curve is rate-independent, which is a test-method independent value provided a suitable, properly operating rheometer is used. For example, the zero- shear viscosity of a substance at 25 °C may be obtained by using commercial rheometers such as an Anton-Parr MCR-301 rheometer or a TA Instruments AR-2000 rheometer equipped with cone-and- plate fixtures of suitable diameter to generate adequate torque signal at a series of low shear rates, such as 0.01 s-1, 0.1 s-1and 1.0 s-1while not exceeding the torque limits of the transducer. Alternatively, the viscosity measurements may be obtained using an ARES-G2 rotational rheometer, commercially available from TA Instruments using a steady rate sweep from 0.1 to 10 s-1on a 25 mm cone and plate. If the zero-shear plateau region cannot be observed at shear rates accessible to the rheometer or viscometer, we report the viscosity measured at a standard shear rate of 0.1 s-1at 25 °C. All Shore hardness measurements were measured using either the Shore A method or the Shore 00 method as defined in ASTM D2240-15 dependent on the apparent softness, with the Shore 00 method being used for softer elastomers. Swelling Reference Examples In order to show that low viscosity organopolysiloxane polymers will swell a hydrosilylation cured silicone elastomer when the elastomer is soaked / immersed in a low viscosity silicone fluid, the following experiment was undertaken. A slab of a cured liquid silicone rubber material was prepared following the instructions supplied with the product for mixing the two-part compositions provided. Three 1-inch x 1-inch x 0.08 in (2.54cm x 2.54 cm x 2mm) rectangular samples were cut from the slabs. The three rectangular samples were immersed in three dimethylvinyl terminated polydimethylsiloxanes having different viscosities, the first had an approximate viscosity of 30mPa.s, the second fluid had an approximate viscosity of 430mPa.s and the third fluid had an approximate viscosity of 44,000mPa.s in each case the values provided were zero-shear values measured as described above at 25oC. Each sample remained immersed in the respective fluid for 24 hours after which they were analysed for changes. It was found that the sample immersed in the fluid having a viscosity of 44,000mPa.s gained no mass and did not change in size. The sample immersed in the 430 mPa.s fluid had an 8% increase in mass and size. The sample immersed in 30 mPa.s fluid had a 30% increase in mass and size. Hence, it can be seen that swelling did take place when the samples were immersed in low viscosity silicone fluids, but no noticeable swelling occurred when immersed in the fluid having a viscosity of 44,000mPa.s. An analogous experiment was undertaken in order to show that low viscosity silicone fluids swell a condensation cured silicone elastomer when the elastomer was immersed in a low viscosity silicone fluid. A condensation cured slab of silicone elastomer, made from a two-part sealant composition using a tin catalyst, was prepared and the test repeated. In the case of the condensation cured samples, it was found that the sample immersed in 44,000mPa.s gained no mass and did not change in size. The sample soaked in 430 mPa.s fluid had an 8% increase in mass and size. The sample immersed in 30 mPa.s fluid had a 30% increase in mass and size. Hence, it can be seen that swelling does take place when the samples were immersed in low viscosity silicone fluids and as a consequence similar swelling occurs to the preformed silicone elastomeric particulates. Laboratory Preparation of particulates In one example, cured silicone rubber block samples were shredded with a paper shredder and cut with scissors until they were of a predetermined size of less than 2cm particle size. They were then fed into to a MikroTMUMP-B mill commercially available from Hosokawa Micron Corporation. The shredded / cut rubber samples were mixed with dry ice (the dry ice had been previously crushed to a powder using mortar and pestle) in a weight ratio of approximately 1:1 in order to reduce the temperature of the rubber and help stiffen it for milling. The rubber / dry ice mixture was then fed into the mill using a knife blade rotor rotating at an rpm of > 10,000. The rubber was then allowed to leave the milling chamber through a stainless-steel screen when it was cut finer than the hole size of the screen. The screen had 2-3 mm diameter round holes for a first pass. The rubber milled in the first pass was then subjected to a second pass with dry ice again as before and fed through the MikroTMUMP-B mill for a second pass this time using a 1mm slotted screen. Analytical Assessment of Particle Size. The particle size distribution of the milled preformed silicone elastomeric particulates was measured using laser diffraction. A Beckman CoulterTMLS 13320 Particle Size Analyzer with the Tornado (dry) module was used. Approximately 25 mL of a milled bulk solids sample was added into a vial, which was placed in the LS 13320 Tornado module which was then activated. When activated, the Tornado module automatically vacuumed the sample past a laser and the diffraction signal of the sample was measured. Beckman CoulterTMsoftware then used to deconvolute the diffraction signal to a particle size distribution determined using Fraunhofer diffraction model with the average value noted below. A hydrosilylation curable silicone rubber coating composition was prepared using the composition depicted in Table 1.

[0002] Table 1: hydrosilylation curable silicone rubber coating composition (LSR 1) (wt. %) Part A Part Part Part B(1) B(2) B(3) 58 86 9 5 0 7 9 0 6 8 2 .0 e reac ve swe ng use agen was vny me y erm na e poy me ys oxane u aving a viscosity of 450mPa.s. The cross-linker used in the above composition was a trimethyl terminated methylhydrogen dimethylsiloxane polymer having a zero-shear viscosity of about 5 mPa.s at 25oC. The above hydrosilylation curable silicone rubber coating composition (LSR 1) was then used in a series of examples, either alone or in combination with a variety of preformed silicone elastomeric materials all having an average particle size of 1 mm or less as depicted in Tables 2a and 2b below. The mechanically recycled particulates were loaded in an amount of 22.5 parts by weight per 100 parts by weight of Part B(1) of LSR 1, except for Ref.1 which contained no mechanically recycled particulates and Ex.2 which had 67.5 parts by weight per 100 parts by weight of Part B(1) of LSR 1. So, when initially mixed the mixture comprised approximately 80 wt. % of the Part B(1) composition of LSR1 and about 20 wt. % of the particulates in Ex.1 and Ex.3 to 5 and about 60 wt. % of particulates and 40 wt. % of Part B(1) of LSR 1 in Ex.2. Table 2a: Samples of Part B(1) compositions of LSR1 (Table 1) alone or mixed silicone rubber particulates (in parts by weight relative to 100 parts by weight of Part B(1) of LSR 1) prior to swelling Ref.1 Ex.1 Ex.2 Ex.3 Ex.4 Ex.5 Part B(1) of LSR 1 100 100 100 100 100 100 5 LSR recycled Rubber Particulates 1 were prepared from a hydrosilylation cured liquid silicone rubber (LSR) coating composition coating composition containing an HMDZ treated fumed silica, designed to be a high elongation coating having a Shore A hardness of about 10. Because Shore A hardness measurements are less accurate for soft materials registering values of 10 or less on the Shore A scale, measurements were also taken using the Shore 00 hardness scale. In this case, the original airbag LSR coating has an equivalent Shore 00 hardness value of about 80. LSR recycled Rubber Particulates 2 were prepared from a hydrosilylation cured liquid silicone rubber (LSR) coating composition coating composition containing an HMDZ treated fumed silica, having a Shore A hardness of about 50. HCR recycled Rubber Particulates 1 were prepared from a peroxide cured high consistency rubber (HCR) having a Shore A hardness of about 60 used in gasketing applications. RTV sealant recycled Particulates 1 were prepared from 2-part tin-cured room temperature vulcanizate sealant having a Shore A hardness of about 40 which was cured in a sheet at ambient laboratory conditions for a period of 30 days. The Examples provided (Ex.1 to 5) rely on swelling agent in the Part B(1) composition of LSR 1for swelling the mechanically recycled silicone rubber particulates using the Part B(1) composition depicted in Table 1. The relevant mechanically recycled particulates as indicated from Table 2a were prepared as described above and introduced into the Part B(1) composition. The particulates were allowed to swell by interaction with the reactive swelling agent provided in the Part B(1) composition. Swelling took place for approximately 24 hours. After completion of the swelling step the resulting mixture containing 100 parts by weight of the Part B(1) composition incorporating the swelled particulates was inter-mixed with 100 parts by weight of the part A composition of LSR 1 ( a Part A : Part B(1) weight ratio of 1 : 1 excluding the particulates) resulting in there being equivalent to about 10 wt. % (unswelled weight) of particulates in the total composition of Part A + Part B(1) in Ex.1 and Ex.3 to 5 and approximately 30wt. % (unswelled weight) of particulates in the total composition of Part A + Part B(1) in Ex.2. The resulting hydrosilylation curable silicone rubber coating compositions were cured by compression molding the different compositions in rrectangular slabs of dimensions 5 inches by 5 inches by 0.08 inches (12.7cm x 12.7 cm x 0.2cm) at 150 °C for 10 minutes. A further set of four examples were prepared using Part B(2) or Part B (3) compositions of LSR 1 as indicated in Table: 2b below: Table 2b: Samples of Part B(2) and Part B(3) compositions of LSR1 (Table 1) mixed with silicone rubber particulates (in parts by weight relative to 100 parts by weight of the respective Part B(2) or Part B(3) compositions Part B(1) of LSR 1) prior to swelling. Ex.6 Ex.7 Ex.8 Ex.9 Part B(2) of composition of LSR 1 100 , p , pp g g , g g e expressed in parts by weight per 100 parts by weight of respective Part B(2) or Part B(3) compositions. In the case of Ex.6 the compositions used for Ex.1 were repeated but in this instance the particulates were pre-swelled for 24 hours in the reactive swelling agent and then the swelled particulates and remaining swelling agent were added into the Part B(2) composition and stirred before the Part B(2) composition was inter-mixed with the Part A composition and the resulting combined composition was cured in the same manner as described above. In the cases of Ex.7, Ex.8, and Ex.9, a Part B(3) composition was utilised which contained 5 wt. % of reactive swelling agent. In Ex.7 the particulates were just added into the Part B(3) composition and were swelled by the reactive swelling agent therein. Swelling took place for approximately 24 hours after which the Part B(3) composition containing the swelled particulates was inter-mixed with 100 parts by weight of the part A composition of LSR 1 (a Part A : Part B(3) weight ratio of 1 : 1 excluding the particulates) resulting in there being equivalent to about 10 wt. % (unswelled weight) of particulates in the total composition of Part A + Part B(3). Ex.8 and Ex.9 underwent a capping procedure. In the case of Ex.8 the particulates were immersed in a combination of an unreactive swelling agent (plasticizer) in combination with 1-dodecene which was provided to react with any residual Si-H groups available for reaction in or on the particulates. The particulates were allowed to interact with the 1-dodecene for approximately 3 days (72 hours) prior to being introduced into a pre-prepared Part B(3) composition and the method was then the same as described above. In Ex.8 once the part A and part B compositions have been mixed together there is approximately 9.88 wt.% of particulates present (dry / unswelled weight), 2.27 wt.% of unreactive swelling agent, and 0.09 wt.% of the capping agent in the final mixed formulation. In Ex.9 the particulates were immersed and pre-swelled in a combination of reactive swelling agent and 1-dodecene in the amounts depicted in Table 2b above for 24 hours. After the 24-hour period the resulting particulate mixture was introduced into the Part B(3) composition and the method was subsequently the same as above. The loading of capping agent in both Ex.8 and 9 was selected to be approximately a molar equivalent to the number of moles of residual Si-H anticipated to be present in the particulates, assuming full vinyl conversion during the original cure of the elastomer prior to physical recycling. The resulting Ex.6, 7, 8 and 9 hydrosilylation curable silicone rubber coating compositions were cured by compression molding the different compositions in rrectangular slabs of dimensions 5 inches by 5 inches by 2 inches (12.7cm x 12.7 cm x 5.08cm) at 150 °C for 10 minutes. Subsequently, the cured samples were analysed for their physical properties. For tensile testing, tensile bars with a 40 mm gauge length were cut from the rectangular slab using a metal die, otherwise Tensile strength, elongation at break and modulus results were determined in accordance with ASTM D412. Five replicates were performed for each sample. Shore 00 hardness was determined using ASTM D2240-15. The physical property results are depicted in Table 3. The reference sample indicates the sort of physical property results obtained for standard cured airbag coating materials.

[0003] Table 3: Physical Property results of C.1 and Ex.1 to 8 Modulus at 100% Tensile Strength Elongation at Shore 00 hardness extension (MPa) (MPa) break (%) that can adequately capture the tensile properties of the Reference material can be prepared using the varying types of mechanically recycle particulates described herein. It was found that physical properties were sufficient to provide adequate pressure retention upon airbag deployment, at optimized coat weights. Indeed, coatings of Ex.1 to 9 were coated onto mini airbags comprising one-piece-woven PET fabric using a lab scale blade coater from Mathis AG of Switzerland. The coatings had an approximate coat weight of 65-70 g / m2. Subsequent to the coating operation the coated airbags were cured for 90 seconds at 190 °C. Suitability for use as airbag coatings was achieved. Deployment testing was performed by inflating bags to 70 kPa and monitoring the pressure decay as a function of time after deployment. For example, in the case of a mini airbag coated with a layer of Ex.5 coating composition were found to meet the 6 second pressure retention requirement for a coated airbag at a coat weight of 65 g / m2. This coat weight is comparable to coat weights required for typical commercial materials such as similar to coatings made from the reference composition (Ref) despite the slightly lower tensile properties. Despite having a nearly identical coat weight, Ex.5 is expected to provide desired performance attributes at lower costs and improved LCA compared to Ref.1 by virtue of containing proportionately less new silicone composition, as shown at the bottom of Table 1. Whilst Ex.1 to 9 provide lower elongation and tensile strength values than the reference it can be seen from Table 4 below comparing Ex.1 and Ex.3 with identical airbag coatings other than using smaller particle size particulates (e)(i) gave improved physical property results with the smaller particulates than those used in Table 3. In Table 4 the results of Ex.1 and Ex.3 are repeated. These contained particulates having an average particle size of 1000µm and are compared with Ex.1* which had the exact same composition and was prepared in the exact same way, the only difference being that the particulates had an average particle size of 400µm and Ex.3* was similarly an identical composition and was made in an identical method but the particulates had an average particle size of 200µm.
