ABSTRACT:
A heat-curable electrocoating composition containing a polymer having pendant mercaptan groups and cross-linking agent having alpha-,beta-ethylenically unsaturated carbonyl groups can be electrodeposited onto a cathode substrate disposed within an aqueous electrocoating bath. Upon electrodeposition onto the substrate, the mercaptan groups cross-link with the alpha-,beta-ethylenically unsaturated carbonyl groups upon curing to form a fully cured electrodeposited coating on the cathode substrate.
