Patent ID: 7943698

Claim:
An ambient temperature curing coating composition comprising the crosslinked reaction product of: (a) an amino-functional compound, wherein the amino-functional compound is a bis-silylamine of general formula: (R 2 ) b (R 1 Y) a Si-Q 1 -NH-Q 2 -(NH-Q 3 ) n -Si(YR 1 ) a (R 2 ) b n≧0 a=3-b b=0,1,2 each Y is independently a heteroatom, selected from O, N; if Y is N, then the valency of Y is 2; if Y is O, then the valency of Y is 1; each R 1 is independently a monovalent radical including but not limited to linear alkyl, branched alkyl, cycloalkyl, aryl, allyl, or aralkyl; R 1 is an alkyl of 1-10 carbon atoms, each R 1 may be the same or different; R 2 is a monovalent radical, and can include a heteroatom not directly bonded to the silicon atom, including but not limited to, linear alkyl, branched alkyl, cycloalkyl, aryl, allyl, or aralkyl and wherein each R 2 may be the same or different; Q 1 , Q 2 , Q 3 is a divalent bridging group, including but not limited to an alkylene, and can be branched or cyclic; each Q can be the same or different; and (b) an acrylic polymer containing pendant organofunctional α-silane groups.
