Abstract
Disclosed herein are cathodic electrodepositable coating baths containing lead cyanamide as a supplementary catalyst. It has been found that using lead cyanamide in conjunction with a primary metal catalyst (e.g. dibutyltin oxide) results in an electrocoat system with superior underbake cure without sacrificing chipping characteristics during overbake cure.
