Coating composition for cationic electrocoating from aqueous bath and bath for same.

摘要

A coating composition for electrocoating from an aqueous bath, the composition comprising a cationic amine-functional copolymer mixture and an aminoplast resin. The copolymer includes from 3% to 35% of a monomer having a basic amino group, from 20% to 35% of isobutoxymethyl acrylamide or methacrylamide and up to 15% of a monomer providing active hydrogen atoms co-reactive with N-methylol functionality, the balance being nonreactive monomers.
