DUAL CURE COATING COMPOSITIONS HAVING IMPROVED SCRATCH RESISTANCE, COATED SUBSTRATES AND METHODS RELATED THERETO} [2] Over the past decade, there has been cooperation to reduce air pollution due to volatile solvents released during the painting process. However, it is often difficult to achieve a high quality smooth coating finish as required by industry or the automotive industry without using organic solvents that play a large role in the flow and leveling of the coating. In addition to achieving a scratch-free appearance, these coatings must be robust, wear resistant, economical and easy to apply. [3] The use of conventional thermosetting resins for coating compositions, which can be cured by heat, is undesirable because the resin must be thinned with a solvent so as to be easily applied to the substrate. Using a solvent is economically and environmentally undesirable because the solvent must be removed from the coating composition during curing. [4] To reduce this problem, radiation sensitive materials have been developed which are cured by ionizing radiation or actinic radiation, which alleviate or eliminate the need for solvents. However, the flexibility of the radiation cured coatings is less than desirable and the properties of such coating compositions are not readily modified for different applications. [5] U.S. Patent No. 4,025,407 discloses thinning conventional thermosetting resins with radiation or actinic radiation sensitive materials and introducing the coatings into ionizing radiation or actinic radiation and then into conventional curing mechanisms for thermosetting resins. In Example 1 of this patent, a thermosetting resin, in particular a radiation sensitive monomer, is mixed with radiation insensitive aliphatic diisocyanate, TiO 2 and black tint, the coating is irradiated with an electron beam and heated at 140 ° F. for 24 hours. Prepared by wet curing. [6] U. S. Patent No. 5,571, 297 discloses a binding membrane comprising a mixture of abrasion grit and a compound having at least one radiation curable action and at least one thermosetting action. [7] Color + transparent coating systems comprising applying a dyed or colored undercoat to a substrate and then applying a clear coat over the undercoat have become increasingly popular as an original finish for many consumer products, including for example automobiles. . The color + transparent coating system mostly has significant appearance characteristics such as gloss and clarity due to the transparent film. Such color + transparent coating systems have gained popularity for automotive, aerospace applications, flooring such as ceramic tiles and wooden floors, packaging coatings, and the like. [8] Topcoat film-forming compositions, particularly those used in the manufacture of clearcoats in automotive and industrial color + transparent coating systems, are susceptible to damage from a number of environmental factors as well as defects occurring during the assembly process. Defects during the assembling process include paint defects during application or curing of the undercoat or the transparent coat. Damage caused by environmental factors may include acidic precipitation, exposure to sunlight, high relative humidity and high temperatures, defects caused by contact with scratched surfaces, and small, hard objects that produce fragments on the coated surface. There is a defect due to the collision. [9] Typically, harder, more highly crosslinked films may exhibit improved scratch resistance, but the films are less flexible and are resistant to fragmentation or thermal cracking due to the film's softness resulting from high crosslink density. Much more sensitive. More flexible, less crosslinked films do not tend to fragment or thermally crack, but are susceptible to scratching, water staining, and susceptibility to acid corrosion due to the low crosslink density of the cured film. [10] Moreover, elastomeric automotive parts and accessories, such as elastomeric bumpers and hoods, are typically "separately" coated and shipped to an automobile assembly plant. Coating compositions applied to such elastomeric substrates are typically highly flexible and formulated such that the coating can bend with the substrate without cracking. In order to achieve this essential flexibility, coating compositions used in elastomeric substrates often employ flexible auxiliaries that act to produce coatings with lower crosslink density or lower the overall film glass transition temperature (Tg). It is formulated to include. Acceptable flexibility properties can be achieved by these blending techniques, while the techniques can also produce a more flexible film that is easy to scratch. As a result, much cost and care must be taken to pack the coated parts to prevent scratching the coated surface during shipment to the automotive assembly plant. [11] US Pat. No. 4,822,828 discloses (a) 50 to 85 weight percent vinyl functional silane based on the total weight of the dispersion, (b) 15 to 50 weight percent polyfunctional acrylate based on the total weight of the dispersion, and (c) Optionally, the use of vinyl functional silanes in aqueous radiation curable coating compositions comprising 1 to 3 weight percent photoinitiator. The vinyl functional silane is a partial condensate of silica and silane, wherein at least 60% of the silane is of the general formula (R) a Si (R ') b (R') c where R is allyl or vinyl functional Alkyl and R 'is hydrolyzable alkoxy or methoxy and R "is non-hydrolyzable saturated alkyl, phenyl or siloxy, wherein a + b + c is 4 and a≥1; b≥1; c≥0 Vinyl functional silanes The patent discloses that the coating composition can be cured by applying it to a plastic material and exposing it to ultraviolet or electron beam irradiation to form a substantially transparent wear resistant layer. [12] Despite the recent improvements to color + transparent coating systems, there is still a need in the automotive coatings field for topcoats that have good scratch resistance without the appearance of films. Furthermore, it would be advantageous to provide a topcoat for elastomeric substrates used in the industrial and automotive industries, which is flexible and scratch resistant.

The embedded sample can then be microtome at room temperature by techniques known in the art, such as block surface formation. This zone can be cut using a 45 ° diamond knife mounted in a holder in a "boat-shaped cavity" to capture water. During the cutting process, the zone rises to the surface of the water in the boat-like cavity. Once several cuts reach the interference color from light gold to dark gold (ie, between about 100 and 150 nm thick), individual samples are typically collected on a formvar-carbon coated grating and glass Dry at room temperature on a slide. The samples were then placed in a suitable electron transmission microscope, for example Philips CM12 TEM, and measured at various magnifications, for example 105,000 times, for examination of the particle concentration in the surface area via an electron microscope. The concentration of particles in the surface area of the cured coating can be investigated by visual observation of electron micrography. [217] It is to be understood that the particles may be present in the surface area such that a portion of the particles may at least partially protrude over the cured coating surface unprotected by the organic coating layer. Optionally, the particles may be present in the surface region such that the organic coating layer is between the particles and the exposed air-surface interface of the surface region. [218] In one embodiment, the present invention relates to a cured composition as described above, wherein the average particle diameter of the particles prior to introduction into the coating composition may be less than 100 μm, and the average particle diameter may be less than 50 μm prior to introduction into the coating composition. In another embodiment, the present invention relates to a cured composition as described above, wherein the average particle diameter of the particles is less than 1 to 1000 nm prior to introduction into the curable composition. In another embodiment, the present invention relates to a cured composition as described above, wherein the average particle diameter of the particles is 1 to 100 nm prior to introducing the curable composition. [219] In another embodiment, the present invention relates to a cured composition as described above, wherein the average particle diameter of the particles is 5 to 50 nm prior to introduction into the composition. In another embodiment, the present invention relates to a cured composition as described above, wherein the average particle diameter of the particles is 5-25 nm prior to introduction into the composition. The particle diameter can range between any combination of the above values, including the stated values. [220] In embodiments in which the average particle diameter of the particles is greater than 1 μm, the average particle diameter can be measured according to known laser scattering techniques. For example, the average particle diameter of such particles uses a helium-neon laser with a wavelength of 633 nm to measure the particle diameter, and a horiba, assuming that the particle is spherical, ie the particle diameter refers to the smallest sphere that completely encloses the particle. Measurements were made using a (Horiba) model LA 900 laser diffraction particle size instrument. [221] In embodiments of the invention wherein the particle diameter of the particles is 1 μm or less, the average particle diameter is visually observed by electron micrographing of an electron transmission microscope (TEM) image, the diameter of the particles in the image is determined, and based on the magnification of the TEM image. It can measure by calculating an average particle diameter. Those skilled in the art will understand how to prepare such TEM images, which are described in the Examples described below. In one non-limiting embodiment of the invention, a TEM image with a magnification of 105,000 times was produced and the conversion factor was obtained by dividing the magnification by 1000. When visually observed, the diameter of the particles is measured in millimeters and the measurement is converted to nm using a conversion factor. The diameter of a particle is referred to as the smallest diameter sphere that completely surrounds the particle. [222] The shape (or tissue) of the particles can vary depending on the specific embodiment of the present invention and their intended use. For example, generally spherical tissue (eg, solid beads, microbeads or hollow spheres) may be used, or particles that are tetrahedral, plate-like, or needle-like (extended or fibrous) may be used. In addition, the particles can maintain a hollow internal structure, porous or empty voids, or have a combination of the aforementioned forms, for example porous or solid walls and hollow cores. For more detailed information on suitable particle characteristics, see Handbook of Fillers and Plastics (1987), page 9-10, specifically cited herein. [223] Those skilled in the art will recognize that mixtures of one or more particles having different average particle diameters are introduced into a composition according to the present invention to impart the desired properties and properties to the composition. For example, particles of various particle diameters can be used in the compositions according to the invention. [224] In one embodiment, the present invention provides that when the particles are added to other components that form the composition, the particles are present in the composition in an amount of 0.01 to 75% by weight based on the total weight of the resin solids of the components that form the composition. , To a composition as described above. In another embodiment, the invention provides that the particles are present in the composition in an amount of at least 0.1% by weight, based on the total weight of the resin solids of the components that form the composition, when the particles are added to the other components that form the composition. , The particles may be present in the composition in an amount of at least 0.5% by weight and may also be present in the composition in an amount of at least 5% by weight. [225] In another embodiment, the present invention relates to the above, wherein the particles are present in the composition in an amount of less than 75% by weight, based on the total weight of the resin solids of the components forming the composition, when the particles are added to the other components forming the composition. It relates to a cured composition as one. In a further embodiment, the present invention relates to the above, wherein the particles are present in the composition in an amount of less than 50% by weight, based on the total weight of the resin solids of the components that form the composition, when the particles are added to the other components that form the composition. It relates to a cured composition as one. In another embodiment, the invention relates to the aforementioned, wherein the particles are present in a composition of less than 20% by weight, based on the total weight of the resin solids of the components that form the composition, when the particles are added to other components that form the composition. To a cured composition as such. In another embodiment, the present invention relates to a method wherein the particles are present in the composition in an amount of less than 10% by weight, based on the total weight of the resin solids of the components that form the composition, when the particles are added to other components that form the composition. To a composition as described. The amount of particles present can range between any combination of these values, including the values mentioned. [226] Additionally, in another embodiment, the present invention relates to a composition, wherein one or more surface active agents may be present while forming the composition as described above. One or more surface active agents may be selected from anionic, nonionic and cationic surface active agents. [227] As used herein, "surfactant" means any material that tends to reduce the surface energy or solid surface tension of the cured composition or coating. That is, a cured composition or coating formed from a composition comprising a surface active agent has a lower solid surface tension or surface energy compared to a cured coating formed from a similar composition containing no surface active agent. [228] For the purposes of the present invention, the solid surface tension is determined according to the Owens Wendt method using distilled water and methylene iodide as reagents and using the Rame's-Hart Contact Angle Goniometer. It can be measured. In general, 0.02 cc drops of one reagent were placed on the cured coating surface and the contact angle and their excitation angle were measured using a standard microscope equipped with a goniometer. Contact angles and their angles were measured for 3 drops each. The procedure was then repeated using another reagent. The average value was calculated after six measurements for each reagent. The solid surface tension was then calculated using the Owen-Wenz formula of Equation 1 below: [229] [230] Where [231] γ l is the surface tension of the liquid (methylene is 50.8, distilled water is 72.8), [232] γ d and γ p are dispersion components and polar components (γ d of methylene iodide is 49.5, γ p is 1.3; γ d of distilled water is 21.8, and γ p is 51.0), [233] The cos Φ value was determined by measuring the value of γ. [234] Next, we arranged two equations, one for methylene iodide and the other for water. Only unknowns are γ s d and γ s p . Then we solved two equations for two unknowns. The two components combined represent the total solid surface tension. [235] One or more surface active agents may be selected from amphiphilic reactive functional group-containing polysiloxanes, amphiphilic fluoropolymers and mixtures of the foregoing compounds. In water-soluble or water-dispersible amphiphilic materials, the term "amphoteric" refers to a polymer that retains a hydrophilic polar end and a generally hydrophobic end that is water insoluble. Non-limiting examples of suitable functional group-containing polysiloxanes useful as surface active agents include the polysiloxanes described below.

In another embodiment, the polyacrylate is a polyacrylate comprising, for example, an acid functional monomer such as (meth) acrylic acid and a hydroxyl functional monomer such as hydroxy ethyl (meth) acrylate in the component used. It can have an acid functional group and a hydroxyl functional group which can be provided by preparing. [242] In other embodiments, the reactants may include one or more materials with one or more reactive functional groups that are reversibly blocked with silyl groups. This silyl-blocked material is different from the first material, second material, dual curing material (if present) and curing agent of the composition. Hydrolysis of the silyl groups regenerates reactive functional groups on the material that can be used for further reaction with the curing agent. [243] Suitable silyl blockers are compounds of formula (IX): [244] [245] Where [246] R 1 , R 2 and R 3 are the same or different and each is an alkyl group having 1 to 18 carbon atoms, a phenyl group or an allyl group. [247] Non-limiting examples of suitable functional groups that can be blocked by silyl groups include hydroxyl groups, carbamate groups, carboxyl groups, amide groups and mixtures thereof. In one embodiment, the functional group is a hydroxyl group.

[249] Further examples of compounds suitable for the silylation reaction, and reaction conditions and reagents suitable for the trimethylsilylation reaction, are described in T. Greene et al., Protective Groups in Organic Synthesis , (2d. Ed. 1991), pages 68-86 and 261-263. [250] The backbones of these materials are compounds or polyesters comprising at least one bond selected from ester bonds, urethane bonds, urea bonds, amide bonds, siloxane bonds and ether bonds, acrylic acid polymers, polyurethanes, polyethers, polyureas, polyamides and It may be a polymer such as any of these copolymers. [251] Suitable compounds or polymers having ester groups and one or more reactive functional groups include half-esters formed from the reaction of one or more polyols with one or more 1,2-anhydrides. Semi-esters are preferred because they are relatively low molecular weight and highly reactive with epoxy functional groups. [252] The semi-esters are obtained by reacting a polyol with 1,2-anhydrides under conditions sufficient to open the anhydride to form a semi-ester which is substantially free of polyesteration. This reaction product has a narrow molecular weight distribution and relatively low molecular weight of low viscosity. By "substantially no esterification occurs" is meant that the carboxyl groups formed by the reaction of anhydride are not further esterified by the polyol in a cyclic manner. This means that less than 10% or less than 5% by weight of high molecular weight polyester is formed. [253] 1,2-anhydrides and polyols are generally mixed together and the reaction is carried out in an inert atmosphere such as nitrogen, in the presence of a solvent such as a ketone or an aromatic hydrocarbon to dissolve the solid components and / or to lower the viscosity of the reaction mixture. do. [254] In the desired ring-opening reaction and semi-ester formation, 1,2-dicarboxylic anhydride is used. Reaction with polyols using carboxylic acids instead of anhydrides requires esterification by condensation and removal, and water must be removed by distillation. Under these conditions, the reaction promotes undesirable polyesteration. In addition, the reaction temperature may be low. That is, it may be less than 135 ℃ or 70 to 135 ℃. The reaction time may vary somewhat depending on the reaction temperature and is generally 10 minutes to 24 hours. [255] The equivalent ratio of anhydride to hydroxyl on the polyol may be at least 0.8: 1 to achieve the maximum conversion to the desired semi-ester (anhydrides are considered to be monofunctional). A ratio of less than 0.8: 1 can be used but this ratio increases the formation of lower functional semi-esters. [256] Useful anhydrides include aliphatic, cycloaliphatic, olefinic, cycloolefinic and aromatic anhydrides. Substituted aliphatic and aromatic anhydrides are also useful as long as the substituents do not adversely affect the reactivity of the anhydride or the properties of the resulting polyester. Examples of substituents include chloro, alkyl and alkoxy. Examples of anhydrides include succinic anhydride, methyl succinic anhydride, dodecenyl succinic anhydride, octadecenyl succinic anhydride, phthalic anhydride, tetrahydrophthalic anhydride, methyltetrahydrophthalic anhydride, hexahydrophthalic anhydride, alkyl hexahydrophthalic anhydride (e.g. methyl Hexahydrophthalic anhydride), tetrachlorophthalic anhydride, endomethylene tetrahydrophthalic anhydride, chloric acid anhydride, itaconic anhydride, citraconic anhydride and maleic anhydride. [257] Among the polyols that can be used are simple polyols (ie simple polyols having 2 to 20 carbon atoms), as well as polymeric polyols such as polyester polyols, polyurethane polyols and acrylic acid polyols. [258] Among the simple polyols are diols, triols, tetrols and mixtures thereof. Non-limiting examples of polyols include polyols having 2 to 10 carbon atoms, such as aliphatic polyols. Specific examples include, but are not limited to, the following compositions: di-trimethylol propane (bis (2,2-dimethylol) dibutylether); Pentaerythritol; 1,2,3,4-butanetetrol; Sorbitol; Trimethylolpropane; Trimethylolethane; 1,2,6-hexanetriol; glycerin; Trishydroxyethyl isocyanurate; Dimethylol propionic acid; 1,2,4-butanetriol; TMP / epsilon-caprolactone triol; Ethylene glycol; 1,2-propanediol; 1,3-propanediol; 1,4-butanediol; 1,5-pentanediol; 1,6-hexanediol; 2-ethyl-1,3-hexanediol, neopentyl glycol; Diethylene glycol; Dipropylene glycol; 1,4-cyclohexanedimethanol and 2,2,4-trimethylpentane-1,3-diol. In one embodiment, the polyol is trimethylolpropane. [259] For oligomeric polyols, suitable polyols are polyols prepared from the reaction of triols with diacids such as trimethylol propane / cyclohexane diacid and trimethylol propane / adipic acid. [260] For polymeric polyols, polyester polyols are prepared by esterifying organic polycarboxylic acids or their anhydrides using organic polyols and / or epoxides. Generally, polycarboxylic acids and polyols are aliphatic or aromatic diacids or acid anhydrides and diols. [261] Polyols commonly used to prepare polyesters include trimethylol propane, di-trimethylol propane, alkylene glycols such as ethylene glycol, neopentyl glycol and other glycols such as hydrogenated bisphenol A, cyclohexanediol Cyclohexanedimethanol, reaction products of lactones with diols (e.g., reaction products of epsilon-caprolactone and ethylene glycol), hydroxy-alkylated bisphenols, polyester glycols (e.g. poly (oxytetramethylene ) Glycol) and the like. [262] The acid component of the polyester consists mainly of monomeric carboxylic acids or anhydrides having 2 to 18 carbon atoms per molecule. Among the useful acids are phthalic acid, isophthalic acid, terephthalic acid, tetrahydrophthalic acid, hexahydrophthalic acid, methylhexahydrophthalic acid, adipic acid, azelaic acid, sebacic acid, maleic acid, glutaric acid, chloric acid, tetrachlorophthalic acid and various other Form of dicarboxylic acid. In addition, higher polycarboxylic acids such as trimellitic acid and tricavallylic acid can be used. However, the use of such higher functional polycarboxylic acids is undesirable due to the resulting high viscosity. [263] In addition to polyester polyols formed from polyacids and polyols, polylactone polyesters can also be used. These products are formed from the reaction of lactones such as epsilon-caprolactone with polyols such as ethylene glycol, diethylene glycol and trimethylolpropane. [264] In addition to the polyester polyols, polyurethane polyols can be used, such as polyester-urethane polyols formed from the reaction of organic polyisocyanates with polyester polyols as described above. The organic polyisocyanate allows the product resulting from the reaction with the polyol to contain free hydroxyl groups such that the OH / NCO equivalent ratio is greater than 1: 1. The organic polyisocyanate used to prepare the polyurethane polyols may be aliphatic or aromatic polyisocyanates or mixtures. Diisocyanates can be used and higher polyisocyanates such as triisocyanates can also be used, but this can lead to high viscosity. [265] Examples of suitable diisocyanates are 4,4'-diphenylmethane diisocyanate, 1,4-tetramethylene diisocyanate, isophorone diisocyanate and 4,4'-methylenebis (cyclohexyl isocyanate). Examples of suitable higher functional polyisocyanates are polymethylene polyphenol isocyanates. [266] Some or more or all of the acid functionalities may be silylated. Alternatively, some or more or all of the acid functional groups can be converted to hydroxyl groups by reacting with an epoxy functional material or aliphatic diol as described above to provide an alcoholic hydroxyl group for silylation. [267] Useful epoxy functional materials include glycidyl methacrylate, ethylene oxide, butylene oxide, propylene oxide, cyclohexene oxide, glycidyl ethers (e.g. phenyl glycidyl ether, n-butyl glycidyl ether, cress) Silglycidyl ether and isopropyl glycidyl ether), glycidyl esters such as glycidyl vercetate, such as CARDURA E available from Shell Chemical Co. Epoxy functional monomers), and mixtures of any of these. The equivalent ratio of acid groups on epoxy groups to esters can generally be from 0.1: 1 to 2: 1, 0.5: 1 to 1: 1, typically from 0.8: 1 to 1: 1. [268] Useful aliphatic diols include 1,2-propanediol, 1,3-propanediol, 1,2-butanediol, 1,3-butanediol, 1,2-pentanediol, 1,4-pentanediol, 1,2-hexane Diol, 1,5-hexanediol, 2-ethyl-1,3-hexanediol, diethylene glycol, dipropylene glycol, 1,4-cyclohexanedimethanol, 2,2,4-trimethyl-1,3-pentane Diols containing primary hydroxyls such as diols and 3,3-dimethyl-1,2-butanediol. [269] Non-limiting examples of silylated compounds containing ester groups for use in the coating compositions of the present invention are compounds of formula X: [270] [271] Other useful materials having ester, urethane, urea, amide and / or ether groups and one or more reactive functional groups suitable for silylation have been disclosed above in the discussion of suitable further polymers.
