Catalyzing cationic resin and blocked polyisocyanate with bismuth carboxylate

A method of catalyzing a cationic coating comprising a cationic resin such as an epoxy resin-amine reaction product or a copolymer of a cationic monomer, and a blocked polyisocyanate, wherein a catalyst is added, said catalyst selected from the group consisting of bismuth carboxylate(s) having a hyd...
