Description

COATING COMPOSITIONS COMPRISING A SCUFF RESISTANT COMPONENTCROSS-REFERENCE TO RELATED APPLICATION

[0001] This application claims the benefit of U.S. Provisional Patent Application No. 63 / 649,107 filed May 17, 2024, which is incorporated herein by reference.FIELD OF THE DISCLOSURE

[0002] The present disclosure is directed to coating compositions comprising a scuff resistant component.BACKGROUND OF THE DISCLOSURE

[0003] Coatings used in houses and other buildings are often exposed to external forces that can cause scuffing, scraping, scratching, grazing, abrading, roughening, or chafing to coating layers. This is particularly true in high traffic areas, such as hallways. Coatings having improved scuff resistance are desired.SUMMARY OF THE DISCLOSURE

[0004] The present disclosure is directed to a coating composition comprising a film forming component and a scuff resistant component, wherein the scuff resistant component comprises a silane / silicone / siloxane-based component, and a polyethylene wax component. The present disclosure is further directed to a coating composition comprising a film forming component comprising a first acrylic latex having a Tg of 60°C + / - 10°C, a second acrylic latex having a Tg of 20°C + / - 10°C, and a scuff resistant component.DETAILED DESCRIPTION OF THE DISCLOSURE

[0005] The present disclosure is directed to a coating composition comprising a) a film forming component; and b) a scuff resistant component; wherein the scuff resistant component comprises a silane / silicone / siloxane-based component, and a polyethylene wax component. The present disclosure is further directed to a coating composition comprising a film forming component comprising a first acrylic latex having a Tg of 60°C + / - 10°C, a second acrylic latex having a Tg of 20°C + / - 10°C, and a scuff resistant component.

[0006] Film forming” means that the composition, upon drying / coalescing / hardening and / or curing, can form a continuous film on a surface. This continuous film is often referred to herein as a coating, or coating layer, which terms may be used interchangeably. A film forming component may include, for example, a film-forming resin and a crosslinker therefore. The filmforming component may include a film-forming resin that coalesces or crosslinks with itself.Crosslinker, curing agent and like terms may all be used interchangeably herein, as may dry, coalesce, crosslink, cure, and harden.

[0007] Any suitable resin or combination of resins can be used in the film-forming component, including, epoxy resins, acrylic resins, siloxane resins, polysiloxane resins, silane resins, polyurethane resins, polyurea resins, polyvinyl resins, phenolic resins, urea-formaldehyde resins, polyimide resins, melamine resins, and polyester resins, including alkyd resins. If a siloxane / polysiloxane / silane or silicone resin is used as part of the film-forming component, it is not considered as being part of the silane / silicone / siloxane-based component for purposes of calculating the amount of silane / silicone / siloxane-based component in the composition. Particularly suitable are those resins that, alone and / or in conjunction with a crosslinker, will form a film at ambient conditions; particularly suitable are acrylic latex resins. Film-forming resins used according to the present disclosure may be organic and may contain one or more functional groups that either react with each other or with the functional groups on the crosslinker. Examples of suitable functional groups include, ketone, hydrazide, carbodiimide, oxazoline, epoxy, amine, vinyl, amide, carbamate, urea, mercaptan, carboxylic acid, (meth)acryloyl, isocyanate, alkoxysilyl, anhydride, hydroxyl, alkoxy groups functional groups, and combinations thereof. “Organic” as used herein in reference to film-forming resins means that at least 75 wt% of the monomers used to form the resin are hydrocarbon based, where wt% is based on total weight of the resin monomers.

[0008] Suitable functional groups that can react with each other (i.e. self-crosslinking) include N-methylolamide groups; silane groups having silicon bonded hydrolysable or condensable groups, for example chloro, hydroxy, alkoxy, acetoxy and / or ketoximo groups; ethylenically unsaturated fatty acid groups such as those capable of oxidative drying; azomethine groups; azetidine groups; and groups capable of a thermally reversible Diels-Alder reaction, for example furan / maleimide. If the resin contains functional groups that can react with each other, the resin is considered self-crosslinking and the presence of a curing agent to crosslink that resin may not be necessary.

[0009] The resin may contain a combination of functional groups that can react with each other (self-crosslinking) and functional groups that can react with the functional groups of the curing agent. In such cases, a curing agent may be present; upon cure, two crosslinkingmechanisms will occur - the reaction between functional groups on the crosslinker and the resin and the self-crosslinking reaction of the resin itself.

[0010] A particularly suitable film forming component comprises a first acrylic latex having a Tg of 60°C + / - 10°C and a second acrylic latex having a Tg of 20°C + / - 10°C, such as a first acrylic latex having a Tg of 60°C + / - 5 °C and a second acrylic latex having a Tg of 20°C + / - 5°C. The first acrylic latex and / or second acrylic latex may be self-crosslinking. The first acrylic latex and / or second acrylic latex may comprise crosslinkable monomer residues. A “residue” is that portion of a monomer that exists after the monomer is polymerized. A crosslinkable monomer residue has functionality that can react with a crosslinker. The first acrylic latex and / or the second acrylic latex may comprise both self-crosslinking moieties and crosslinkable monomer residues. Tg as reported herein was determined by DSC. The first and second acrylic latex can be chosen so as to impart desired properties to the end coating. For example, each acrylic latex may be selected to impart durability or hardness, softness, and / or scuff resistance. In this manner, coating layers with multiple properties can be obtained. Suitable acrylic latex resins are widely commercially available such as from BASF, Lubrizol, Dow, Arkema, and Allnex.

[0011] It may be desired to specifically exclude certain compounds from the film forming component. For example, when an acrylic latex is used, the use of wax seeded acrylic latex may be specifically excluded; it will be appreciated that a wax particle may be used as a “seed” for latex formation and may result in the wax being encapsulated by the acrylic. The present acrylic latexes may be formed without the use of such a wax seed or “substantially free” of a wax seeded acrylic latex. This does not preclude the presence in the composition of any compound that might form with a separately added wax component. It may also be desired that the latex be substantially free of a phosphate monomer; that is, the latex is formed without the use of a phosphate monomer. “Substantially free” in the context of the phosphate monomer means less than 0.1 wt% of the monomers used in formation of the latex comprise a phosphate, where wt% is based on the tot al weight of the monomers comprising the film-forming resin. Similarly, the composition may be substantially free of an alkyl phosphate surfactant, where substantially free means less than 1 wt% of the total solid weight of the composition.

[0012] The film forming component may be present in an amount of 25 to 75 wt%, such as 30 to 60 wt% or 35-45 wt%, with wt% based on the total solid weight of the coating composition.

[0013] The coating compositions comprise a scuff resistance component. The term “scuff resistant component” as used herein refers to a component that, when added to a composition, increases the ability of a coating layer deposited from the composition to resist scuffing as compared to a coating layer deposited from the same composition lacking the scuff resistant component. Scuff resistance is often achieved using one or more components, such as slip additives that affect the surface energy of the coating layer. Suitable scuff resistant components according to the present disclosure may have a surface energy of 45mJ / m2or less, such as 40 or less, 35 or less, 30 or less, 25 or less or 20 or less, where surface energy is measured with a Mobile Surface Analyzer (MSA). By reducing the slip resistance of a coating layer, the coating layer has increased scuff resistance. “Scuffing” and like terms refer to any sort of marking that occurs to a coating layer, such as scuffing, marring, color transfer, color change or staining, gloss change, burnishing, scrubbing marks, scraping, scratching, grazing, abrading, roughening, or chafing. “Scuff resistance” and like terms therefore means the ability to resist any such marking. The materials used in the scuff resistant component may be non-reactive; that is, they remain unreacted in the cured coating and are not a pail of nor do they react with the film forming component.

[0014] The scuff resistant component may comprise a silane / silicone / siloxane-based component. A silane / silicone / siloxane-based component is one that contains or is derived from silane (Sikh) and / or silicone and / or contains siloxane functionality. The component may be a silicone emulsion. Examples include poly dimethyl siloxane (“PDMS”) based emulsions, polydiethylsiloxane (“PDES”) based emulsions, other silicone- and copolymer products, and mixtures thereof. The silane / silicone / siloxane may be present in an amount of 0.1 wt% or greater, such as 0.2 wt% or greater, 0.3 wt% or greater, 0.4 wt% or greater, or 0.5 wt% or greater, and / or 2.0 wt% or lower, such as 1.5 wt% or lower, or 0.75 wt% or lower, and / or 0.1 to 2.0 wt%, such as 0.5 to 1.75 wt%, or 0.5 to 1.5 wt%, or 0.75 to 1.5 wt%, where wt% is based on the total weight of the coating composition. For clarity, these wt% represent the amount of silane / silicone / siloxane itself in the composition, and not the amount of emulsion added to the composition. And, as noted above, these amounts do not include any silane / silicone / siloxanethat may be present in the film-forming component. Suitable commercially available silicone emulsions include those available from Dow in their DOWSIL line, Momcntivc, Evonik, Wacker and Byk.

[0015] The scuff resistant component may comprise a polyethylene wax component.Any polyethylene wax and / or polyethylene wax alloy can be used, alone or in combination. For example, the polyethylene wax component may comprise a polyethylene wax and a polyethylene wax alloy. A “polyethylene wax alloy” is a polyethylene wax blend. The polyethylene wax blend can include a blend of polyethylene waxes or a blend of a polyethylene wax with another wax, such as a biobased wax. A biobased wax is one the is derived from a renewal resource, such as plants. Biobased wax is commercially available from Lubrizol, Deurex, Shamrock Technologies, BYK and others. The polyethylene wax may be in solid form such as a powder and / or a crystalline polyethylene wax, and / or may be in the form of a dispersion. The average particle size of the wax, as reported by the manufacturer, can be 0.5 to 50.0 pm, such as 2.0 to 20.0 or 3.0 to 10.0 or 5.5 to 7.5 pm. Combinations of polyethylene wax can be used in the polyethylene wax component, and the entire polyethylene wax component can come from any source desired. The polyethylene wax in the polyethylene wax component may be present in a total amount of 0.1 wt% or greater, such as 0.2 wt% or greater, 0.3 wt% or greater, 0.4 wt% or greater, or 0.5 wt% or greater, and / or less than 3.0 wt%, 2.0 wt% or lower, 1.75 wt% or lower, 1.5wt% or lower, or 0.75 wt% or lower, and / or 0.1 to 2.0 wt%, such as 0.5 to 1.75 wt%, or 0.5 to 1.5 wt%, or 0.75 to 1.5 wt%, where wt% is based on the total weight of the coating composition. For clarity, these wt% represent the amount of actual polyethylene wax in the composition, and not the amount of carrier material, biobased wax, etc. brought into the composition through the polyethylene wax component. Suitable polyethene wax is commercially available from BASF in their JONCRYL line, Micro Powders, Inc., in their MICROSPERSION line, Munzing Chemical in their LUBA-PRINT and SUDRANOL lines, Byk, Shamrock Technologies, Honeywell in their NDUROMATT line and Omya in their OMYAMATT line.

[0016] The polyethylene wax component and / or the scuff resistant component can be substantially free and / or completely free of amide wax, including polyamide wax. “Substantially free” in this context means less than 0.1 wt% amide wax, and “completely free” means that only trace amounts of amide wax, such as would be present as an impurity in another compound, are present, if at all. Wt% here is based on total weight of the scuff resistant component.

[0017] The coating composition may further comprise a matting agent. A matting agent will be understood by those skilled in the art as a component, such as a polymer, oligomer or other organic or inorganic additive, that causes the gloss of the coating layer to be reduced as compared to a composition without the matting agent. Any matting agent can be used according to the present disclosure; they are widely commercially available. Particularly suitable are organic matting agents, such as polyurea matting agents, such as those commercially available from Huber Advanced Materials in their PERGOPAK line, and / or bio-based wax matting agents, such as those commercially available from Shamrock Technologies in their BIOSLIP line.

[0018] The coating composition may further comprise phosphate, such as in the form of an alkyl phosphate monomer incorporated into the resin material and / or an alkyl phosphate surfactant, such as anionic alkyl phosphate ester surfactants or nonionic phosphate ester surfactants. Phosphate, in the residue of a phosphate-containing monomer in the resin and / or an alkylphosphate surfactant may be present in an amount of 0.10 wt% or greater, such as 0.35 wt% or greater, 0.45 wt% or greater, 0.55 wt% or greater, or 0.65 wt% or greater and / or 0.75 wt% or lower, such as 0.65 wt% or lower, 0.50 wt% or lower, 0.40 wt% or lower, 0.35 wt% or lower, and / or 0.25 wt% to 0.75 wt%, such as 0.35 wt% to 0.65 wt%, where wt% is based on the total weight of the coating composition.

[0019] The coating compositions of the present disclosure are liquid and can be water based, or solvent based. “Water based” means the liquid carrier is 50 wt% or more water, and “solvent based” means the liquid carrier is more than 50 wt% solvent, such as an organic solvent such as an alcohol, ketone and the like. A water-based carrier can comprise less than 50% organic solvent.

[0020] Coating compositions according to the present disclosure can be formulated using any means known in the art and further including one or more standard additives such as water, solvents such as organic solvents, pigments, dyes, fillers, abrasion-resistant particles, antioxidants, hindered amine light stabilizers, UV light absorbers and stabilizers, surfactants, flow and surface control agents, thixotropic agents, defoamers, biocides, coalescent agents, rheology modifiers, buffers, reactive diluents, driers, catalysts, reaction inhibitors, adhesion promoting components, such as acids and acid derivatives, phosphatized epoxy, and other customary additives known to those skilled in the ait. Components used according to the present disclosure can be added to the formulation in any desired order.

[0021] It may also be desired to specifically exclude certain other compounds in addition to those already discussed from the present film-forming components and / or coating compositions. For example, the film-forming component and / or the coating composition may be fluorine free, sometimes referred to as “fluorine non intent”. As used herein, fluorine non-intent means that no component comprising fluorine is intentionally added to the composition; any fluorine that is present in the composition is a trace amount, such as would be present as an impurity in another compound, such as less than 0.1 wt% based on the total weight of the composition.

[0022] It may also be desired to specifically exclude from the present compositions polymeric particles having a Shore D hardness of 75 or greater, as measured by ASTM D2240- 15. A particular polymeric particle that may be excluded is a poly alkyl(meth)acry late particle (“PMMA”). It may also be desired to specifically exclude inorganic particles lacking sharp edges and points and having a Mohs hardness of at least 2. Accordingly, the present compositions may be substantially free of polymeric particles having a Shore D hardness of 75 or greater as measured by ASTM D2240-15, and / or inorganic particles lacking sharp edges and points having a Mohs hardness of at least 2, where “substantially free” in this context means less than 1 wt% of each excluded particle is in the composition, where wt% is based on total weight of the composition. For example, the coating compositions of the disclosure may be substantially free of PMMA, and / or ceramic, glass, or aluminosilicate microspheres (i.e., alkali aluminosilicate like sodium aluminosilicate or potassium aluminosilicate).

[0023] The coating compositions of the present disclosure may be one component compositions or “IK” compositions, which are compositions in which all of the ingredients are premixed and stored, and the reactive components do not readily react until exposed to air.

[0024] The present disclosure is further directed to a method for using the coating compositions as described herein to coat a substrate, comprising applying the composition to the substrate and allowing the composition to cure. As noted above, “cure”, “coalesce”, “harden”, “dried” or like terms refers to the process by which a coating composition forms a coating or coating layer as a result of at least some of the functionality on the film-forming resin reacting with itself and / or the functionality of a crosslinker. Such reactions may occur at ambient conditions or at elevated temperatures. “Ambient conditions” refers to room temperature (10°Cto 32°C) and relative humidity of 20 to 80%, while “elevated temperature” generally refers to temperatures 33°C or higher.

[0025] It was a surprising discovery that coating layers deposited from the present coating compositions, particularly when formulated with the first and second acrylic latex materials having the Tg values described above, may have a diiodomethane contact angle of 40 to 70 degrees as measured on a Mobile Surface Analyzer. Thus, the present coating layers exhibit hydrophilic behavior. This was surprising because the addition of a scuff resistant component typically results in increasing the hydrophobic character of a coating layer. Upon inclusion of the scuff resistant component to the compositions of the present disclosure the contact angle remained substantially the same as compared with a coating layer deposited from a similar composition lacking the scuff resistant component. “Substantially the same” in the context of contact angle means within 15 degrees.

[0026] The compositions of the present disclosure can be applied to the surface of a substrate in any number of different ways, such as brushes, rollers, films, trowels, spatulas, dips, spray guns, sprays or applicator guns. Upon application, the coating layer can be cured by any suitable means. Examples include exposure to ambient temperature, induction heating, infrared heating, exposure to actinic radiation, and / or combinations thereof. As noted above, the coating layer may be cured or coalesced at ambient conditions, as defined above.

[0027] The coating compositions may be applied to any substrates known in the ail, for example, architectural components, such as roofs, bricks, vinyl siding, concrete, cement, cement board, MDF (medium density fiberboard) and particle board, gypsum board, wood, wood composite, veneer, stone, metal, plastics, wallpaper and textile, etc., which may be pre primed by waterborne or solvent borne primers. The architectural component may be an interior or exterior component, such as a wall. Walls in high traffic areas are particularly appropriate substrates.

[0028] Automotive substrates, marine substrates, industrial substrates, packaging substrates, wood flooring and furniture, apparel, electronics including housings and circuit boards and including consumer electronics such as housings for computers, notebooks, smartphones, tablets, televisions, gaming equipment, computer equipment, computer accessories, MP3 players, glass and transparencies, sports equipment including golf balls, and the like are also suitable substrates.

[0029] Substrates can be, for example, metallic or non - metallic. Metallic substrates include tin, steel, tin -plated steel, chromium passivated steel, galvanized steel, aluminum, aluminum foil. Metal sheet as used herein refers to flat metal sheet and coiled metal sheet, which is coiled, uncoiled for coating, and then re-coiled for shipment to a manufacturer. Non- metallic substrates include polymeric, plastic, polyester, polyolefin, polyamide, cellulosic, polystyrene, polyacrylic, poly (ethylene naphthalate), polypropylene, polyethylene, nylon, EVOH, polylactic acid, other “green” polymeric substrates, poly(ethyleneterephthalate) (“PET”), polycarbonate, polycarbonate acrylobutadiene styrene (“PC / ABS”), polyamide, glass, paper, cardboard, textiles, leather both synthetic and natural, and those non-metallic substrates listed above as architectural components.

[0030] Any numerical range recited herein is intended to include all sub-ranges subsumed therein. Singular encompasses plural and vice versa. For example, although reference is made herein to “a” film forming component, “a” scuff resistant component, “a” polyethylene wax component, “a” silane / silicone / siloxane component, and the like, one or more of each of these and any other components can be used. Amine includes polyamine. Also, as used herein, the term “polymer” refers to prepolymers, oligomers and both homopolymers and copolymers; the prefix “poly” refers to two or more. When ranges are given, any endpoints of those ranges and / or numbers within those ranges can be combined with the scope of the present disclosure. “Including”, “such as”, “for example” and like terms means “including / such as / for example but not limited to”.

[0138] The following examples are intended to illustrate the disclosure and should not be construed as limiting the disclosure in any way.Example 1 : Semi-gloss pastelTable 1Pitt-Glaze WB1 Gen 2 Semi-gloss Pastel[001391 Paints 23-1A-1C were prepared by using a production batch of PITT-GLAZE WB1 'Semi-gloss pastel and post adding the PDMS and / or polyethylene wax dispersion. These paints were then mixed for approximately 10 minutes and applied to a P-122- ION panel with a 7 mil DOW bar. Panels were dried for 7 days under ambient conditions. 24-12A was prepared by making a lab batch of the production formula. The PDMS, which was 65 wt% solids in water, and polyethylene wax dispersion, which was 64 wt% solids in water with a D50 particle size of 6.5 pm, were post added and mixed for 10 minutes. Testing panels were prepared in the same way as described above. Wt% here is based on the total weight of the composition.

[0140] Scuff testing was performed by creating scuff marks using a hockey puck: 1) in a Byk scrub machine and 2) in a tribometer. The DE values of the films were measured after scuffing in the Byk scrub machine. DE or “Delta E” is the color comparison between two coated substrates on a scale of 0-100, where 0 means the colors are the same and 100 means the colors are opposite (such as black and white). Here, DE measures the shift in color when a hockey puck is used to create black scuff marks on portions of a white panel. The higher the DE value, the less resistant the coating composition is to scuff because the coating composition shifts more in color when it is contacted by the hockey puck. Conversely, the lower the DE value, the more1Commercially available from The Pittsburgh Paints, Co., PITT-GLAZE WB1, both the semi-gloss and eggshell sheens used in the examples, comprises a waterborne epoxy resin, an acrylic resin having a Tg of 60°C and an acrylic resin having a Tg of 20°C.resistant the coating composition is to scuff because the coating composition shifts less in color when it is contacted by the hockey puck. DE was measured using a Datacolor 600 Spectrophotometer. The color measurement was made (and compared) on scuffed and unscuffed portions of the substrate. The coefficient of friction (COF) was measured using a Bruker UMT-3 Tribolab tribometer according to the manufacturer’s instructions. Scuff resistance increases as the COF decreases.Table 2

[0141] The sample with either PDMS or the polyethylene wax (23- IB and 23-1C, respectively) had better scuff resistance overall than the sample with neither (23-1 A). The sample with both (24-12A) had the best results.Example 2: Eggshell pastelTable 3Pitt-Glaze WB1 Gen 2 Eggshell Pastel

[0142] Paint 24- 12 was a production batch of PITT-GLAZE WB 1 Eggshell pastel. Paint 24-12B was prepared using a production formula, but the polyurca matting agent (having a Dso particle size of 6.0-8.5 pm) was added in the grind to reduce gloss and sheen. The PDMS and polyethylene wax dispersion were added in the letdown and stirred for 10 minutes. Paints 23- 19A to 23-19C were prepared following a production formula. The matting agent was added in the grind to reduce gloss and sheen. The PDMS and polyethylene wax dispersion were postadded and stirred for 10 minutes. Each paint was applied to a Leneta P-122- 10N panel with a 7 mil DOW bar. Panels were dried for 7 days under ambient conditions and tested as described in Example 1.Table 4

[0143] The example with both PDMS and the polyethylene wax (24-12B) again gave the best results, with the samples with only one (23-19B and 23-19C) giving better results than the samples with neither (24-12 and 23-19A). Example 23-19A, which had the polyurea matting agent but no scuff resistant component, illustrates that the matting agent was not contributing to scuff resistance.
