Patent ID: 7074856

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 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 nâ‰§0 a=3âˆ’b b=0, 1 or 2 each Y is independently a heteroatom is selected from O or 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 selected from the group consisting of hydrogen, hydrocarbon including but not limited to linear alkyl, or branched alkyl, cycloalkyl, aryl, allyl, or aralkyl; each R 1 may be the same or different; R 2 is a monovalent radical, wherein R 2 can optionally include a heteroatom selected from the group consisting of oxygen, nitrogen, sulfur, wherein R 2 is not directly bonded to the silicon atom, and wherein R 2 is linear or 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 having pendant alkoxysilane and optionally epoxy groups.
