Abstract:
A method of making a cured multilayer coating, the method comprisingapplying by electrophoretic deposition a first curable coating composition (I) to a substrate, the first curable coating composition (I) comprising, (a) a compound comprising one or more active hydrogen-containing groups, and (b) a curing agent comprising one or more groups reactive with active hydrogen-containing groups, applying a second curable coating composition (II) to the applied first curable coating composition (I) while the applied first curable coating composition is in an uncured state, the second curable composition (II) comprising (a) a compound comprising one or more active hydrogen-containing groups, and (b) a curing agent comprising one or more groups reactive with active hydrogen-containing groups, and subjecting the applied first and second curable coating compositions to conditions sufficient to cause curing of both compositions, wherein curing agent (I)(b) is reactive with compound (II)(a) and curing agent (II)(b) is reactive with compound (I)(a) under the applied cure conditions.
