ABSTRACT:
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:in-line-formulae description="In-line Formulae" end="lead"?(R2)b(R1Y)aSi-Q1-NH-Q2-(NH-Q3)n-Si(YR1)a(R2)bin-line-formulae description="In-line Formulae" end="tail"?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 R1is independently a monovalent radical (e.g., hydrogen, hydrocarbon including but not limited to alkyl (linear or brached), cycloalkyl, aryl, allyl, or aralkyl. Preferably, R1is an alkyl of 1–10 carbon atoms. Each R1may be the same or different; R2is 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 R2may be the same or different. Q1, Q2, Q3is a divalent bridging group, including but not limited to an alkylene, but preferably is a C1–C12alkylene, 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.
