ABSTRACT:
The invention provides cathodic electrocoat compositions having a carbamate functional resin with a cationic salting site, a crosslinking agent reactive with the carbamate functional resin and a carbonate curing agent. The invention also provides methods of cathodically electrodepositing a coating on a substrate using the coating compositions of the invention. The compositions of the invention provide urethane crosslinking sites without the use of disadvantageous blocked isocyanates and cure at temperatures lower than prior art cathodic electrocoat compositions.
