ABSTRACT:
Cathodic electrocoat compositions containing self-crosslinking polymers are described. The polymers of the invention are formed from an epoxide-functional prepolymer having polyepoxide and extender segments. Each extender segment has at least one pendant hydroxyalkyl carbamate group. The prepolymer is reacted with an amine compound having at least one blocked primary amine group and at least one epoxide-reactive group. The primary amine group is unblocked and the resultant polymer is dispersed in water with the aid of a neutralizing acid.
