  • Ambient temperature curing coating composition
    Patent number: 7452945
    Abstract: Ambient temperature curing coating composition comprising—a branched alkoxy-functional polysiloxane having the formula R2-O-[Si(R1)2—O]n—R2, wherein each R1 is selected from the group consisting of alkyl, aryl, and alkoxy groups having up to six carbon atoms, and Osi(OR3)3 groups, wherein each R3 independently has the same meaning as R1, each R2 is selected from the group consisting of hydrogen and alkyl and aryl groups having up to six carbon atoms, and wherein n is selected such that the molecular weight of the polysiloxanes is in the range of from 500 to about 2,000,—a catalyst, and—an acrylic polymer. The acrylic polymer is substantially free of functional groups that can react with the polysiloxane or with the catalyst in the coating composition.
