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: (R2)b(R1Y)aSi-Q1-NH-Q2-(NH-Q3)n-Si(YR1)a(R2)b wherein n≧0, a=3−b, b=0,1,2 and wherein 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 R1 is independently a monovalent radical (e.g., hydrogen, hydrocarbon including but not limited to alkyl (linear or brached), cycloalkyl, aryl, allyl, or aralkyl. Preferably, R1 is an alkyl of 1–10 carbon atoms. Each R1 may be the same or different; R2 is a monovalent radical, and can include heteroatoms (e.g., oxygen, nitrogen, sulfur) not directly bonded to the silicon atom, including but not limited to, alkyl (linear or branched), cycloalkyl, aryl, allyl, or aralkyl. Each R2 may be the same or different. Q1, Q2, Q3 is a divalent bridging group, including but not limited to an alkylene, but preferably is a C1–C12 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. The invention can be further crosslinked with reactive polysiloxanes.
