    摘要: The present disclosure is directed to an anticrater additive that is useful for providing a smooth surface to a cured layer of an electrocoating composition on a substrate. The anticrater additive comprises the reaction product of a polyisocyanate with an acrylic polymer having one isocyanate reactive functional group. The acrylic polymer can be an acrylic polymer that is terminated with a chain transfer agent. Also disclosed is an electrocoat composition comprising the anticrater additive and a substrate coated with a cured layer of the electrocoat composition.
