Description

[0001] This application is a divisional application of the invention patent application with application number 201780008473.8, application date January 25, 2017, and invention name “Anti-fouling silicone coating composition”.

[0002] This application claims priority to provisional U.S. patent application No. 62 / 287,647, filed on January 27, 2016, the entire contents of which are incorporated herein by reference. Technical Field

[0003] Provided herein is a silicone coating composition, and more particularly a silicone coating composition that exhibits lower dirt pick up than conventional silicone coatings. Background Art

[0004] Coatings have been widely used in many fields. In the use of silicone elastomeric coatings, properties such as water resistance, durability, flexibility, and resistance to UV and thermal cracking are important in various applications in which the silicone elastomeric coatings are used. Due to the low glass transition temperature (Tg) of silicone, elastomeric coatings containing silicone have a softer outer surface, which leads to stickiness and increased staining.

[0005] The traditional approach for improving stain resistance is to increase the Tg of the coating, essentially creating a harder outer surface at the expense of elongation. Therefore, one of the challenges has always been to achieve an optimal hardness level without compromising elongation values, both of which are important in architectural coating applications.

[0006] Other approaches to improving stain resistance have included the use of highly cross-linked polymers, which result in a low-tack surface that hinders stain penetration. While this approach is commonly used in automotive coating applications and architectural organic coatings, silicone elastomeric coatings offer unique challenges, including the need to retain a minimum level of elongation.

[0007] Therefore, there still exists a need for a silicone-based elastomeric coating composition that not only improves stain resistance but also simultaneously overcomes other problems that conventional silicone-based elastomeric coating compositions have not yet satisfactorily addressed.

[0094] In one embodiment of the present invention, the elastomeric coating composition includes a polyether silane in combination with a filler, such as a lamellar structural filler (e.g., mica). The presence of both the polyether silane and the filler in the coating composition provides improved stain resistance compared to either the polyether silane alone or the filler alone.

[0095] In one embodiment, the coating composition of the present invention can be formulated as an elastomeric coating composition. The term elastomeric according to the present invention means that the composition can provide effective UV, weathering and water protection when applied to a substrate without causing the coating to over-harden over time, which can lead to visible pitting, cracking and peeling of the coating from the substrate. Such elasticity (elastomeric properties) of the coating can be recognized by those skilled in the art through visual inspection of the coating. In one embodiment, the elastomeric advantages of the coating composition can be provided when the coating provides the necessary modulus and elongation levels and the necessary stability and UV resistance levels, as described herein.

[0096] Except in the examples, or where otherwise indicated, all numbers expressing amounts of material, reaction conditions, durations, quantitative properties of materials, and so forth, mentioned in the specification and claims are to be understood as being modified in all instances by the term "about", whether or not the term "about" is used in the phrase.

[0097] It will be understood that any numerical range recited herein, if recited in the examples or anywhere else in the specification, includes all sub-ranges within that range and any combination of endpoints of such ranges or sub-ranges.

[0098] It will also be understood herein that any of the components of the present invention, when they are described by any specific generic concept or a specific generic concept described in the Examples section of the specification, can be used in one embodiment to define an alternative corresponding definition of any endpoint of the range described for that component elsewhere in the specification, and can therefore be used in a non-limiting embodiment to replace the endpoint of the range described elsewhere.

[0099] It will also be understood that any compound, material or substance explicitly or implicitly disclosed in the specification and / or recited in the claims as belonging to a group of structurally, compositionally and / or functionally related compounds, materials or substances includes individual representatives of the group and all combinations thereof.

[0100] According to the present disclosure, reference is made to a substance, component or ingredient that is present just prior to first contact, in-situ formation, blending or mixing with one or more other substances, components or ingredients. A substance, component or ingredient identified as a reaction product, resulting mixture, etc., can acquire an identity, property or characteristic by chemical reaction or transformation during the process of contact, in-situ formation, blending or mixing operations if performed in accordance with the present disclosure using common sense and the ordinary skills of personnel (e.g., chemists) in the relevant field. The conversion of chemical reactants or starting materials to chemical products or final materials is a continuously evolving process, which is independent of the speed at which it occurs. Therefore, when such a conversion process is in progress, there may be a mixture of starting and final materials and intermediate species, which may be easy or difficult to detect by existing analytical techniques known to those skilled in the art depending on their kinetic lifetimes.

[0101] Reactants and components represented by chemical names or formulas in the specification or its claims, whether represented in singular or plural form, can be identified when they exist before contacting other substances represented by chemical names or chemical types (e.g., other reactants or solvents). Preliminary and / or transitional chemical changes, conversions or reactions carried out in the resulting mixture, solution, or reaction medium, if present, can be identified as intermediate species, masterbatches, etc., and can have a utility different from that of the reaction product or final material. Other successive changes, conversions or reactions can be caused by bringing together specified reactants and / or components under conditions required by the present disclosure. In these other successive changes, conversions or reactions, the reactants, ingredients or components brought together can identify or indicate the reaction product or final material.

[0102] In describing the product of the invention as a reaction product of initial materials, the initial species mentioned are mentioned and it should be noted that additional materials may be added to the initial mixture of synthetic precursors. These additional materials may be reactive or non-reactive. A defining feature of the invention is that the reaction product is obtained by the reaction of at least the components listed as disclosed. Non-reactive components are added to the reaction mixture to act as a diluent or to impart additional properties that are unrelated to the properties of the composition prepared as the reaction product. Thus, for example, a particulate solid such as a pigment may be dispersed into the reaction mixture before, during or after the reaction to produce a reaction product composition that additionally includes a non-reactive component such as a pigment. Additional reactive components may also be added; such components may react with the initial reactants or they may react with the reaction product; the term "reaction product" is intended to include the above-mentioned possible substances as well as the addition of non-reactive components.

[0103] As used herein, the phrase "comprising" or "comprises" should also be understood to include the more restrictive transition phrases "essentially consisting of" and "consisting of," which should include components (a)-(d) and optionally (e) described herein, as well as any optional additives described herein, or in more specific embodiments, only components (a)-(d) and optionally (e).

[0104] As used herein with respect to hydrocarbon radicals, the term "monovalent" means that the radical is capable of forming one covalent bond per radical, the term "divalent" means that the radical is capable of forming two covalent bonds per radical, and the term "trivalent" means that the radical is capable of forming three covalent bonds per radical. In general, a monovalent radical may be represented as having been obtained from a saturated hydrocarbon compound by conceptually removing one hydrogen atom from the compound, a divalent radical may be represented as having been obtained from a saturated hydrocarbon compound by conceptually removing two hydrogen atoms from the compound, and a trivalent radical may be represented as having been obtained from a saturated hydrocarbon compound by conceptually removing three hydrogen atoms from the compound. For example, the ethyl radical, i.e., the -CH2CH3 radical, is a monovalent radical; the dimethyl radical, i.e., the -(CH2)2- radical, is a divalent radical and the ethanetriyl radical, i.e.,

[0105]

[0106] The free radicals are trivalent free radicals, each of which can be represented as having been obtained by conceptually removing one or more hydrogen atoms from the saturated hydrocarbon ethane.

[0107] As used herein, the term "hydrocarbon radical", "hydrocarbon group" or "hydrocarbon moiety" all equally refer to a straight chain or branched hydrocarbon radical, preferably containing 1-6 carbon atoms per radical, which may be saturated or unsaturated and may be optionally substituted or interrupted by one or more atoms or functional groups such as carboxyl, cyano, hydroxyl, halogen and oxy. Suitable monovalent hydrocarbon radicals may include, for example, alkyl, alkenyl, alkynyl, hydroxyalkyl, cyanoalkyl, carboxyalkyl, alkoxy, oxaalkyl, alkylcarbonyloxaalkylene, carboxamide and haloalkyl, such as methyl, ethyl, sec-butyl, tert-butyl, vinyl, propenyl, butynyl, hydroxypropyl, cyanoethyl, butoxy, carboxymethyl, chloromethyl and 3,3,3-fluoropropyl.

[0108] Suitable divalent hydrocarbon radicals include, for example, linear or branched alkylene radicals (eg, methylene, dimethylene, trimethylene, ethylethylene, 2-methyltrimethylene, 2,2-dimethyltrimethylene) and linear or branched oxyalkylene radicals (eg, methyleneoxypropylene).

[0109] Suitable trivalent acyclic hydrocarbon radicals include, for example, alkanetriyl radicals (eg, 1,1,2-ethanetriyl, 1,2,4-butanetriyl, 1,2,8-octanetriyl, 1,2,4-cyclohexanetriyl) and oxaalkanetriyl radicals (eg, 1,2,6-triyl-4-oxahexane).

[0110] As used herein, the term "alkyl" means a linear or branched monovalent hydrocarbon radical. In a preferred embodiment, the monovalent alkyl is selected from a linear or branched alkyl containing 1 to 6 carbons per group, such as methyl, ethyl, propyl, isopropyl, n-butyl, isobutyl, sec-butyl, tert-butyl, pentyl and hexyl.

[0111] As used herein, the term "alkenyl" means a straight-chain or branched monovalent terminally unsaturated hydrocarbon radical preferably containing 2-6 carbon atoms per radical, for example, ethenyl, vinyl, allyl, 2-propenyl, 3-butenyl and 5-hexenyl.

[0112] In one non-limiting embodiment herein, some specific non-limiting examples of hydrocarbon radicals that can be used herein are methyl, ethyl, vinyl, allyl, n-propyl, isopropyl, n-butyl, isobutyl, tert-butyl, n-pentyl, isopentyl, neopentyl and tert-pentyl; hexyl, such as n-hexyl; and 2,2,4-trimethylpentyl.

[0113] In one embodiment of the present invention, component (a) is a condensation-effective polymer having two or more silicon atoms. As used herein, the term "condensation-effective" is understood to mean that the polymer is capable of condensation by a condensation reaction. Condensation reactions and reaction conditions such as reaction time, temperature and pressure are well known to those skilled in the art.

[0114] In one embodiment, the polycondensation-effective polymer (a) having two or more silicon atoms is preferably a silane and / or an organosilicon compound, more preferably an organosilicon compound in another embodiment, even more preferably a linear organosilicon compound in another embodiment, and most preferably a fully hydroxyl-terminated and / or alkoxy-terminated organosilicon compound in another embodiment.
