Abstract
Disclosed is a composite coating, comprising a substrate; one or more primer coating layers disposed on said substrate; and at least one topcoat layer disposed on the outermost primer coating layer, wherein said outermost primer coating layer is obtained by reaction of a primer composition comprising an acrylic resin having primary carbamate functionality and an aminoplast resin.
Claims18
A composite coating, comprising a substrate;
- at least one primer coating layers disposed on said substrate;
- and at least one topcoat layer disposed on the outermost primer coating layer, wherein said outermost primer coating layer is obtained by curing a primer composition by the reaction of:
- (a) an acrylic resin having at least one primary carbamate group having a structure of --O--C(.dbd.O)--NH.sub.2 and
- (b) an aminoplast resin.
1 more element
A method of coating a substrate, comprising the steps of:
- (a) applying a primer coating composition, said primer coating composition comprising an acrylic resin having at least one primary carbamate group having a structure of --O--C(.dbd.O)--NH.sub.2 and an aminoplast resin;
- (b) curing the applied primer coating composition to form a primer coating layer;
- (c) applying a topcoat composition over the primer coating layer;
- and
- (d) curing the applied topcoat composition to form a topcoat layer.
