ABSTRACT:
A metal-coupling composition composed of silane cross-linking and coupling agents wherein the coupling agent includes a vinyl moiety. The coupling composition is a replacement for iron-phosphatizing/chromate primering and chromate primering in zinc phosphatizing processes. In a preferred embodiment, the silane cross-linking agent has the following formula:and X is a trivalent group, each Y is independently a divalent group or series of divalent groups, each Q is independently —R or —OR and each R is independently a C1-10alkyl group or aryl group, and —OR group(s) are hydrolysable;and the silane coupling agent has the following formula:each Q is independently —R or —OR and each R is independently a C1-10alkyl group or aryl group, and —OR group(s) are hydrolysable;
