Abstract
A composition is provided comprising a reaction product of (1) a bismuth compound; and (2) an heterocyclic compound having mercapto functionality. Such compositions are useful in electrodepositable compositions further comprising an active hydrogen-containing, cationic salt group-containing resin and a capped polyisocyanate curing agent. These electrodepositable compositions may be prepared without the use of conventional lead or tin catalysts and exhibit excellent properties as cured coatings.
