Description

"Two-component curable system, its cured composition, its use and methods"

[0001] Priority is claimed for European patent application no. 23 178 839.9 which was filed on 13 June 2023.

[0002] The invention relates to a two-component, fast-curing system based on moisture-curable prepolymers, preferably silyl-modified prepolymers (SMPs). By mixing the first component with the second component, the resulting mixture cures in a relatively short period of time. The two-component, fast-curing system is useful as an adhesive or sealant and can be used with standard equipment for applying two-component systems.

[0003] Adhesives and sealants based on silyl-modified prepolymers are known as typical solutions without pretreatment. Due to the intensification of regulatory restrictions, the chemistry of silane-terminated prepolymers focuses on environmentally friendly solutions. Adhesives and sealants based on silyl-modified prepolymers are known, for example, EP 3 546 541 A1, CN 109 880 570 A, US 6 762 242 B1, US 2007 0237912 A1, US 2007 0088110 A1, US 2010 0197855 A1, US 2011 0232825 A1, US 2011 0308730 A1, US 2012 0225983 A1, US 2012 0055105 A1, US 2014 0228515 A1, WO 2014 073593 A1, WO 2015 / 185642 A1, WO 2017 142714 A1, WO 2017 189057 A1, US 2018 0134932 A1, WO 2018 074925 A1, US 2019 0048190 A1, US 2019 0144717 A1, US 2019 0233335 A1 and WO 2022 122782 A1.

[0004] Adhesives and sealants based on silyl-modified prepolymers are typically one-component adhesives. These one-component systems are typically slow-reacting, water-diffusion controlled products. They do not contain moisture, but absorb water from Petition 870250082373, dated 12 / 09 / 2025, page 89 / 402 2 / 120 ambient conditions, for example, air humidity. Curing times are therefore relatively long, for example, from 12 to 24 hours.

[0005] Fast curing can be achieved by providing adhesives and sealants based on silyl-modified prepolymers in the form of two-component systems where one of the two components is water-free and comprises the silyl-modified prepolymer, while the other of the two components is an accelerator paste (booster system), typically comprising water, in order to eliminate the slow dependence on ambient humidity. However, the accelerator paste (booster system) typically has a comparatively small volume which, before application, needs to be mixed with a comparatively large volume of the other component containing the silyl-modified prepolymer. Consequently, such fast-curing two-component systems require mixing ratios of the two components to each other of typically 40:1 to 100:1.

[0006] However, such two-component systems have several disadvantages due to the high mixing ratio. The dosage needs to be very specific and precise to handle the large volumetric difference between the main component and the accelerator paste. Such two-component systems cannot be applied using commonly used standard dispensing equipment, customized for 1:1 or 2:1 mixing ratios. Only special dispensing and mixing tools, available on the market but not well accepted due to high costs and limitations arising from the multiplicity of suppliers of different adhesive systems, can be used.

[0007] When such two-component systems are formulated to allow a lower mixing ratio, for example, 1:1 or 2:1, the volume of the accelerator paste (booster system) is increased by the addition of Petition 870250082373, dated 12 / 09 / 2025, page 90 / 402 3 / 120 plasticizer or binder, which, however, compromises the mechanical properties of the cured sealant or adhesive.

[0008] Document WO 2020 067877 A1 refers to a silyl-modified finished polymer used in a composition for use as a sealant or adhesive, and especially in combination with a specific booster comprising additives.

[0009] In addition, adhesive or sealant compositions need to satisfy certain performance properties, such as high strength combined with high elongation, but also durable adhesion under various climatic conditions. Climate cycle tests have been developed by original equipment manufacturers (OEMs) involving testing samples under adverse conditions, such as poultice at 70 °C with a freeze-thaw step. Modern adhesive or sealant compositions need to pass these tests.

[0010] Conventional adhesive or sealant compositions are frequently based on polyurethanes containing reactive isocyanate groups, such as toluene diisocyanate (TDI), bisphenyl methylene diisocyanate (MDI), hexamethylene diisocyanate (HDI), naphthalene diisocyanate (NDI), and dicyclohexylurea diisocyanate. Such isocyanate products are hazardous because they are potent irritants to the mucous membranes of the eyes and the gastrointestinal and respiratory tracts. The health effects of isocyanate exposure include skin and mucous membrane irritation, chest tightness, and difficulty breathing. Isocyanates include compounds classified as potential human carcinogens and known to cause cancer in animals. The main effects of hazardous exposures are occupational asthma and other lung problems, as well as irritation of the eyes, nose, throat, and skin. Petition 870250082373, dated 12 / 09 / 2025, page 91 / 402 4 / 120

[0011] Furthermore, conventional adhesive or sealant compositions often contain phthalates as plasticizers. Phthalate plasticizers do not chemically bind to cured adhesive compositions but can leach, migrate, or evaporate into indoor air. Building materials, such as vinyl flooring and other consumer products containing phthalates, can result in human exposure through direct contact and use, indirectly through leaching into other products, or general environmental contamination. Humans are exposed through ingestion, inhalation, and dermal exposure throughout their lives. Many phthalates are hormone-disrupting chemicals that interfere with testosterone production. Prenatal exposure to certain phthalates causes common adverse effects on male reproductive development in animals, causing what is known as "phthalate syndrome," which has many similarities to "testicular dysgenesis syndrome" in humans.

[0012] There is therefore a demand for adhesive or sealant compositions that do not contain isocyanates or phthalates. Although certain silicone polymer-based adhesive compositions, for example, polysiloxanes, are also well-known sealants, durable elastic adhesive compositions that achieve performance equivalent to that of polyurethane prepolymer-based compositions have not been available for decades.

[0013] Furthermore, conventional adhesive or sealant compositions often require pre-treatment of the substrate surfaces before the compositions can be applied to them in order to provide satisfactory adhesion. Such pre-treatment, however, is time-consuming and laborious, and there is a demand for adhesive or sealant compositions that do not require such pre-treatment, but which still provide excellent adhesion to surfaces of various materials, including glass, plastic and metals. Petition 870250082373, dated 12 / 09 / 2025, page 92 / 402 5 / 120

[0014] Additionally, after a certain period of use or, for example, after an accident, adhesive bonds or seals that need repair are renewed. However, conventional adhesive or sealant compositions are often difficult to remove or repair, especially when bonded to polyurethane substrates. Therefore, it would be desirable to provide adhesive or sealant compositions that facilitate renewal and repair.

[0015] It is an object of the invention to provide adhesive or sealant compositions that overcome the disadvantages of the prior art and that satisfy one or more of the above needs.

[0016] This objective was achieved by the subject matter of the claims of the present invention.

[0017] Surprisingly, it has been found that two-component fast-curing systems can be supplied in mixing ratios of around 1:1 or 2:1 (v / v) that do not need to contain significant amounts of fillers, binders, plasticizers or other inert constituents in the booster paste so as not to compromise the mechanical properties of the cured compositions (adhesives and / or sealants).

[0018] In particular, it has been surprisingly found that silyl-modified prepolymers can be stabilized even in the presence of water without premature curing. According to the prior art, the moisture-curable prepolymer (e.g., silyl-modified prepolymer), on the one hand, and the accelerator (e.g., water), on the other, must be strictly separated from each other during storage to prevent premature viscosity buildup and curing. In contrast, the invention provides storage-stable two-component systems in which, during storage, the moisture-curable prepolymer (e.g., silyl-modified prepolymer) is in direct contact with water. Petition 870250082373, dated 12 / 09 / 2025, page 93 / 402 6 / 120

[0019] Consequently, the total amount of moisture-curable prepolymer (e.g., silyl-modified prepolymer) can be distributed between the first and second components of the two-component curable system. The volume of the first component and the volume of the second component can thus be adjusted to ratios of, for example, about 1:1 or 2:1 (v / v), without the need to add large amounts of fillers, binders, plasticizers, or other inert constituents. When the two components are mixed, the entire mixture begins to cure.

[0020] Without intending to limit oneself to any scientific theory, it appears that moisture-curable prepolymers, especially silyl-modified prepolymers, can be stabilized in the presence of water by certain additives at elevated pH values. When the first component, which contains such a water-stabilized silyl-modified prepolymer at an elevated pH value, is mixed with the second component, which preferably contains a curing catalyst, the pH value of the resulting mixture is reduced, thus decreasing the stabilization of the silyl-modified prepolymer, so that rapid curing is induced. Curing is preferably, but not necessarily need to be, promoted by the presence of a curing catalyst in the second component. In certain embodiments, the change in pH value alone may be sufficient to induce rapid curing, even in the absence of a curing catalyst.If the resulting pH value is too low or too high, the curing mechanism will be acid- or base-catalyzed, so a curing catalyst may not be necessary. If the resulting pH value is closer to neutral, a curing catalyst is usually required to achieve rapid curing. The need for a catalyst depends on the resulting pH after mixing and the pH before mixing. Furthermore, it appears that the amount of curing catalyst, if present, may also play a role in overcoming the stabilizing effect, thus inducing rapid curing. Petition 870250082373, dated 12 / 09 / 2025, pp. 94 / 402 7 / 120

[0021] During storage, i.e., before mixing with the second component which preferably contains a curing catalyst (and typically no water), the silyl-modified prepolymer mixture and water can be stabilized by a high pH value. Additives that contribute to stabilization (i.e., to prevent premature curing) include Na+ ions, K+ ions, metal hydroxides (such as Al(OH)3), metal oxides (such as Al2O3, MgO and ZnO), SiO2, natural or synthetic minerals that contain or form, in contact with water, Si-OH groups (including minerals comprising Al2O3, MgO, ZnO, SiO2), carbon black, graphene, graphene oxide, organomodified graphene, nitrides (such as AlN and BN) and graphite.

[0022] It appears that all these additives can interact with silanol groups of at least partially hydrolyzed silyl-modified prepolymer and stabilize them, for example, by electrostatic repulsion under a specific pH condition, influenced by the electrostatic nature of the functionalized silane and the silyl-modified prepolymer, respectively.

[0023] It appears that certain fillers, such as silicates, in particular talc, MgO, ZnO, Al2O3 and graphene oxide, are able to interact with silanol groups and complex silanol groups. And also, Na+ ions, K+ ions, etc., stabilize the silyl-modified prepolymer in the presence of water. It appears that metal ions and metal oxides form stable silanol complexes and suppress the condensation of active silanol species in a basic environment.

[0024] Depending on the pH value, the amount of ions needed to provide a satisfactory stabilizing effect will vary. It appears that the higher the pH value, the lower the amount of ions needed for stabilization.

[0025] Surprisingly, it was found that the pH value and the content of donors for Na+ ions (Na donors) are relevant to the Petition 870250082373, dated 12 / 09 / 2025, page 95 / 402 8 / 120 Stability of a two-component system, in particular to stabilize a moisture-curable prepolymer, preferably a silyl-modified prepolymer, in the presence of water. It was found that a pH value of 5 to 10, preferably 7 to 10, can stabilize the two-component system. Furthermore, it was found that a content of Na+ ion donors (Na donors), preferably Na2O, NaOH or a mixture thereof, of at least about 0.03% by weight, preferably at least about 0.04% by weight, can stabilize the two-component system. The combination of a pH value of 5 to 10, preferably 7 to 10, and a content of Na+ ion donors (Na donors), preferably Na2O, NaOH or a mixture thereof, of at least about 0.03% by weight, preferably at least about 0.04% by weight, is particularly useful for stabilizing the two-component system.

[0026] Surprisingly, it has been discovered that several properties of a two-component system can be manipulated by combining the pH value, the presence and quantity of Na+ and / or K+ ions, the presence and quantity of metal oxides capable of forming stable silanol complexes, the presence and quantity of metal catalysts, and the presence and quantity of amine catalysts. The properties that can be manipulated include, among others, cure kinetics, latency, open time, strength buildup, and shelf life.

[0027] The invention allows mixing ratios of up to 1:1 (v / v) without compromising mechanical properties. Water as a cure and silyl-terminated prepolymers of any chemical structure can be combined with adequate storage stability, but without any dilution by fillers, binders, plasticizers or other inert materials that would otherwise compromise the mechanical properties. Furthermore, the pairing component containing silyl-modified stabilized prepolymer and water (first component) can be combined with different components of prepolymer modified with Petition 870250082373, dated 12 / 09 / 2025, page 96 / 402 9 / 120 silyl (second component) to easily alter the material properties of the resulting mixtures.

[0028] The invention allows combining moisture-curable prepolymer and water in a very stable manner. This stabilized formulation (first component) will not gain viscosity or cure until mixed with the other component (second component) of the two-component system, which preferably contains a curing catalyst. Only when mixed (e.g., statically or dynamically) will the change in pH value and / or the curing catalyst of the other component (second component) trigger curing to form a bond and / or seal.

[0029] Moisture stabilization also facilitates the manufacturing process of the two-component system according to the invention, as laborious steps such as drying fillers and other components can be omitted. The presence of water does not need to be minimized or completely eliminated.

[0030] A first aspect of the invention relates to a two-component curable system, preferably an adhesive and / or a sealant, comprising or consisting essentially of (a) a first component comprising one or more moisture-curable prepolymers; optionally, water; and one or more of the following: one or more basic inorganic charges or their anhydrides; a constituent of graphene; a natural or synthetic silicate; Petition 870250082373, dated 12 / 09 / 2025, page 97 / 402 10 / 120 carbon black; expandable graphite; wherein the first component is free of curing catalyst; and (b) a second component, optionally but preferably comprising one or more curing catalysts; preferably wherein the first component comprises one or more moisture-curable prepolymers; one or more basic inorganic feedstocks or their anhydrides; and optionally, but preferably, water.

[0031] Preferably, the two-component curable system according to the invention comprises or consists essentially of (a) a first component comprising one or more moisture-curable prepolymers; one or more basic inorganic charges or their anhydrides; optionally, water; wherein the first component is free of curing catalyst; and (b) a second component, optionally but preferably comprising one or more curing catalysts.

[0032] For the purposes of the present invention, unless expressly stated otherwise, percentages are expressed as a percentage by weight and ppm as a percentage by weight. Unless expressly stated otherwise, any standards such as EN ISO, ASTM and similar standards are in their official version valid as of January 1, 2023. Petition 870250082373, dated 12 / 09 / 2025, page 98 / 402 11 / 120

[0033] The expression “consists essentially of” means a content of at least about 95% by weight, preferably at least about 99% by weight, in relation to the total weight of the component to which the definition refers.

[0034] The system according to the invention is a two-component system, comprising a first component and a second component. The first component is spatially separated from the second component, for example, in separate cartridges or other suitable containers. Preferably, the two-component system essentially consists of the first component and the second component. However, it is considered that, in addition to the first component and the second component, the two-component system according to the invention may comprise one or more additional components and, therefore, may be considered a multi-component system.

[0035] The two-component system, according to the invention, is preferably a ready-to-use composition that already contains all the ingredients necessary for the desired purpose. In particular, before use, the two-component curable system, according to the invention, preferably does not require the addition of any other additives; it only requires mixing the first component and the second component together under ambient conditions, for example, at room temperature (23 °C).

[0036] The two-component system, according to the invention, is curable, that is, it is capable of autonomously undergoing a curing reaction, typically by crosslinking, after mixing the first component with the second component with each other.

[0037] Composition is useful, among other things, for uniting and joining similar and dissimilar substrates. Petition 870250082373, dated 12 / 09 / 2025, page 99 / 402 12 / 120

[0038] For the purposes of the present invention, a prepolymer (polymer precursor) is a monomer or system of monomers that have reacted to an intermediate molecular weight state. This material is capable of further polymerization by reactive groups to a fully cured high molecular weight state. Prepolymers include mixtures of reactive polymers with unreacted monomers. The prepolymer is moisture curable, i.e., upon contact with moisture, it undergoes spontaneous curing, optionally also involving other ingredients contained in the composition, such as curing agents.

[0039] In preferred embodiments of the two-component curable system according to the invention, one or more moisture-curable prepolymers comprise or consist essentially of one or more silyl-modified prepolymers.

[0040] The two-component curable system, according to the invention, may comprise a single moisture-curable prepolymer or a mixture of two or more moisture-curable prepolymers in both components. In the case of the presence of two or more moisture-curable prepolymers, all weights and percentages refer to the total weight of all moisture-curable prepolymers contained in the two-component curable system.

[0041] Preferably, the silyl-modified prepolymer comprises a polymeric structure and one or more hydrolyzable silyl groups.

[0042] It is considered that at least a portion of the hydrolyzable silyl groups may be present in hydrolyzed form. Thus, for example, when the hydrolyzable silyl group is a methoxysilyl group, it may be at least partially hydrolyzed into methanol and a silanol group (R3Si-OCH3 + H2O -> R3Si-OH + HOCH3). Petition 870250082373, dated 12 / 09 / 2025, pp. 100 / 402 13 / 120

[0043] The functional or silyl-modified prepolymer may be a silyl-modified polyether or another type of monomer combination to form a prepolymer formulation. This includes typical silane-terminated PU prepolymers with any type of functionalized silane.

[0044] This silyl-modified prepolymer can be used for all components of a two- or more-component adhesive system. Both components may also contain fillers such as calcium carbonate, kaolin, bentonite, metal oxides and their hydroxides, such as aluminum trihydrate, carbon black, layered silicates, and other natural or synthetic minerals.

[0045] Examples of silyl-modified polymers include, but are not limited to, silyl-modified polyethers and copolyethers, silyl-modified polyisobutylenes (SMPIB), silyl-modified polyacrylates and copolyacrylates (SMA), and silyl-modified polyurethanes (SPUR, PUH).

[0046] Preferably, the silyl-modified prepolymer has a non-siliconic structure, more preferably a polyether structure. For example, the silyl-modified prepolymer can be a dimethoxysilyl-modified polymer, a trimethoxysilyl-modified polymer, or a triethoxysilyl-modified polymer. For example, the silyl-modified prepolymer can be a silyl-modified polyether or copolyether.

[0047] In this embodiment, silyl-modified prepolymers may contain heteroatoms such as N, O, S or other urethane functional groups between the monomeric units to provide different properties targeting different applications and functions.

[0048] For the purposes of this description, a prepolymer (polymer precursor) is a monomer or system of monomers that have reacted to a Petition 870250082373, dated 12 / 09 / 2025, page 101 / 402 14 / 120 intermediate molecular weight state. This material is capable of further polymerization by reactive groups to a fully cured high molecular weight state. Prepolymers encompass mixtures of reactive polymers with unreacted monomers. The prepolymer is moisture curable, i.e., upon contact with moisture, it undergoes spontaneous curing, optionally also involving other ingredients contained in the composition, such as curing agents.

[0049] Moisture-curable prepolymers are known to a person skilled in the art and are commercially available.

[0050] In preferred embodiments of the two-component curable system according to the invention, the moisture-curable prepolymer is a silyl-modified prepolymer. Since the preferred silyl-modified polymer is a curable prepolymer, it is a reactive prepolymer (reactive silyl-modified prepolymer). Silyl-modified prepolymers (SMPs, silane-modified polymers, modified silane polymers, MS polymers, silane-terminated polymers, etc.) are known to those skilled in the art and are commercially available. For details on silyl-modified prepolymers, see, for example, SM Guillaume, Advances in the synthesis of silyl-modified polymers (SMPs), Polym. Chem., 2018, 9, 1911-1926; A. Pizzi et al., Handbook of Adhesive Technology, CRC Press, 3rd edition, 2018.Examples of silyl-modified polymers include, but are not limited to, silyl-modified polyethers and copolyethers, silyl-modified polyisobutylenes (SMPIB), silyl-modified polyacrylates and copolyacrylates (SMA), and silyl-modified polyurethanes (SPUR, PUH).

[0051] Preferably, the silyl-modified prepolymer has a non-silicone structure, more preferably this silyl-modified prepolymer has a polyether structure. For example, the silyl-modified prepolymer can be a polymer modified with Petition 870250082373, dated 12 / 09 / 2025, page 102 / 402 15 / 120 dimethoxysilyl, a polymer modified with trimethoxysilyl or a polymer modified with triethoxysilyl. For example, the silyl-modified prepolymer may be a silyl-modified polyether or copolyether.

[0052] The preferred silyl-modified prepolymers according to the invention are selected from silyl-modified polyethers or copolyethers, preferably silyl-terminated polyethers or copolyethers, for example, silyl-modified polyethylene glycols, silyl-modified polypropylene glycols and the like; Silyl-modified polyurethanes, preferably silyl-terminated polyurethanes; and silyl-modified acrylates, preferably silyl-terminated acrylates.

[0053] In preferred embodiments, the silyl-modified prepolymer has two ends and is terminated with one or more hydrolyzable silyl groups at one end (semi-telechellic) or at both ends (telechellic); preferably at both ends; and / or has side chains containing one or more hydrolyzable silyl groups.

[0054] Preferably, hydrolysis of at least one of the one or more hydrolyzable silyl groups leads to the formation of a silanol group.

[0055] Preferably, the condensation of the silanol group with another silanol group or with a hydrolyzable silyl group leads to the formation of a siloxane group.

[0056] Preferably, one or more hydrolyzable silyl groups, independently of each other, are Petition 870250082373, dated 12 / 09 / 2025, p. 103 / 402 16 / 120 monopodal silyl groups of general formula (I) (I) , or silyl dipodal groups of general formula (II) (II) wherein, in each case, R1, R2, R3, R4, R5 and R6, independently of each other, are selected from substituents forming silicon-carbon bonds selected from the group consisting of -C1-12-alkyl, -C1-6-alkylene-O-C1-6-alkyl, C6-10-aryl, -C1-6-alkylene-C6-10-aryl, -C1-6-alkylene-O-C6-10-aryl; substituents that form silicon-oxygen bonds selected from the group consisting of -O-C1-12-alkyl, -O-C1-6-alkylene-O-C1-6alkyl, -O-C6-10-aryl, -O-C1-6-alkylene-C6-10-aryl, -O-C1-6-alkylene-OC6-10-aryl, -OC(=O)-C1-12-alkyl, -OC(=O)-C1-6-alkylene-O-C1-6-alkyl, -OC(=O)-C6-10-aryl, -OC(=O)-C1-6-alkylene-C6-10-aryl, -OC(=O)-C1-6alkylene-C6-10-aryl; substituents forming silicon-halogen bonds selected from the group consisting of -F, -Cl, -Br, -I; Petition 870250082373, dated 12 / 09 / 2025, page 104 / 402 17 / 120 provided that at least about one of R1, R2 and R3, and at least about one of R4, R5 and R6 is not a substituent forming silicon-carbon bonds; preferably provided that at least about one of R1, R2 and R3, and at least about one of R4, R5 and R6 is selected from substituents forming silicon-carbon-oxygen bonds; “A” represents -N< or -CH<; and “m” and “n”, independently of each other, are an integer within the range of 0 to 18, preferably 1, 2, 3 or 4.
