Patent ID: 8809479

Claim:
A moisture-curable resin composition comprising: (a) a moisture-curable polymer having at least one hydrolysable silyl group wherein the polymer is represented by the general Formula (3): wherein: each occurrence of R 6 is independently a monovalent or polyvalent organic polymer fragment having a number average molecular weight of from 500 to 25,000 grams per mole and derived from a hydroxyl-terminated polypropylene oxide having a terminal ethylenic unsaturation of less than 0.02 milliequivalents per gram polyol and containing at least one urethane functional group; each occurrence of R 7 is independently a divalent alkylene group containing from 1 to 6 carbon atoms; each occurrence of A 1 is divalent oxygen (—O—); each occurrence of A 2 is substituted nitrogen of the structure —NR 8 —, wherein R 8 is hydrogen; each occurrence of X 1 is independently R 9 O—, wherein each R 9 is independently hydrogen or an alkyl group containing from 1 to 4 carbon atoms; each occurrence of X 2 and X 3 is independently selected from the group consisting of R 9 O— and R 10 wherein each R 9 is independently hydrogen or an alkyl group containing from 1 to 4 carbon atoms and each R 10 is independently an alkyl group containing from 1 to 4 carbon atoms; and, each occurrence of subscripts e and f is independently an integer wherein e is 1 and f is 1 to 6; (b) a reactive modifier of the general Formula (2): G 2 [-SiR 4 c (OR 5 ) 3-c ] d (Formula 2) wherein: G 2 is selected from the group consisting of a monovalent or divalent linear hydrocarbon group containing from 3 to 16 carbon atoms; each occurrence of R 4 is monovalent alkyl group containing from 1 to 4 carbon atoms; each occurrence of R 5 is monovalent alkyl group containing from 1 to 4 carbon atoms; each occurrence of c and d is independently an integer, wherein; c is 0 or 1; and d is 1 or 2 with the provisos that, (i) when G 2 contains a heteroatom, the terminal atoms of G 2 are carbon atoms; and (ii) when the silicon atom is attached to G 2 , the silicon atom is covalently bonded to a terminal carbon of G 2 ; and (c) at least one catalyst which is a compound selected from the group consisting of organic dibutyltin, zirconium complex, aluminum chelate, titanic chelate, organic zinc, organic cobalt, organic iron, organic nickel, organobismuth and amine for catalyzing the reaction between the moisture-curable polymer (a) and reactive modifier (b) under moisture curing conditions; and wherein component (b) is present in an amount of from 20 weight percent to 40 weight percent and component (c) is present in an amount of from 0.1 to 3 weight percent, based upon the total weight of components (a), (b) and (c).
