Abstract: The present invention is directed to a polymer comprising the reaction product of (i) a monomer comprising at least two ethylenically unsaturated double bonds; (ii) a monomer comprising a carbon atom that is connected to four moieties wherein one of said moieties comprises a hydrogen atom and the remainder of said moieties comprises an alkyl group, wherein one of the alkyl group containing moieties comprises an ethylenically unsaturated double bond, and wherein none of the alkyl group containing moieties form a cycloaliphatic ring; (iii) at least one monomer that is reactive with (i) and/or (ii); wherein the reaction product is not further reacted with any other monomer comprising an ethylenically unsaturated double bond; and wherein said reaction product comprises a reactive functional group.

Abstract: There is disclosed herein a composite coating comprising a colored base coat over which is applied a clear top coat, the improvement comprising the base coat which comprises a liquid crosslinkable composition comprising a polyepoxide and a polyacid curing agent; said composition is characterized in that it is substantially free of a cure catalyst, and the top coat comprises a cure catalyst system in an amount sufficient to cure both the base coat and the top coat.

Abstract: Disclosed is a composition comprising (A) a silicon-containing resin having in a molecule thereof at least one silicon atom connected to a hydrolyzable group and/or a hydroxyl group, and (B) a cure promoting catalyst system for the silicon-containing resin. The catalyst system comprises a compound containing a fluoride ion. Also disclosed is a composition comprising such a silicon-containing resin, and a catalyst system comprising a compound containing a fluoride ion in combination with an organotin compound.
