ABSTRACT:
The heat-curable coating agent according to the invention contains a combination of a binder, which possesses basic nitrogen groups and is rendered water-dilutable by protonation with an acid, and a crosslinking agent and, if required, pigments, fillers, corrosion inhibitors, surface coating assistants and catalysts, and the binder used is a reaction product of a dicarboxylic acid or of a dicarboxylate or of a (meth)acrylate oligomer or polymer with an adduct of a di- or triglycidyl ether and a polyamine, the polyamine containing 2 or more amine nitrogen atoms per molecule and one or more alkylene chains of 3 or more carbon atoms between the amino groups, and has an NH amine number of from 50 to 150 mg of KOH/g and is combined with aminoplasts and/or phenoplasts as crosslinking agents.
The novel coating agent is useful as a binder for the cathodic electrocoating of metal articles.
