Patent ID: 7459515

Claim:
A fast-curing modified siloxane protective coating composition comprising: an alkoxy- or silanol-functional silicone intermediate,wherein the alkoxy- or silanol-functional silicone intermediate has the eneral formula where each R 1 is selected from the group consisting of a hydroxy group and alkyl, aryl, and alkoxy groups having up to about six carbon atoms, each R 2 is selected from the group consisting of hydrogen and alkyl and aryl groups having up to six carbon atoms, and wherein “n ” is selected so that the silicone intermediate have an average molecular weight in the range of from about 400 to about 10 000; at least one acetoacetate-functional amine reactive ingredient; an epoxy-functional ingredient; a curing agent selected from the group consisting of amines, aminosilanes, ketimines, aldimines and mixtures thereof; and water, wherein the acetoacetate-functional amine reactive ingredient undergoes a cross-linking reaction with the curing agent, wherein the combined composition reacts to form a fully cross-linked enamine polysiloxane structure.
