Method And Composition For Treating Metal Surfaces Using A Polymer Blend And An Organo-Functional Silane
US Patent:
2005008, Apr 21, 2005
Filed:
Oct 21, 2003
Appl. No.:
10/690349
Inventors:
Jose Rivera - Philadelphia PA, US
Norman Schellenger - Lansdale PA, US
Norman Schellenger - Lansdale PA, US
International Classification:
C08L001/00
US Classification:
427331000, 524522000, 524524000, 524262000
Abstract:
A method and composition for treating metal surfaces improves the paint adhesion of the metal surface, particularly its resistance to delamination of paint over a stressed area in the finished metal upon exposure to hot water. The composition is an aqueous composition of an organo-functional silane, a compound of a group IV-B element, and a polymer blend having a plurality of carboxylic functional groups and a plurality of hydroxyl groups. The method includes contacting a metal surface, such as aluminum, with the composition. The polymer blend is preferably a mixture of polymethylvinylether-co-maleic acid and polyvinyl alcohol. The organo-functional silane is preferably an epoxy silane.
