ABSTRACT:
A low cure cathodic electrodepositable resin is disclosed. The backbone of the resin is a polyepoxide amine adduct which is crosslinked with aminoplast resins and catalyzed by metal catalysts. The resin is capable of curing in a basic environment at a temperature below 150.degree. C. The resin can be salted with an acid and can be dissolved or dispersed in water. The aqueous dispersions can then be formulated into electrocoat primer coatings for metal objects.
