Abstract
Heat curable binders for use in cathodically depositable aqueous coating compositions characterized in that curing is through alpha, beta-double bonds on end or side chains of the binders are described. The binders are the reaction product of 2 moles of a diepoxide; 1 mole of a secondary-secondary or primary-tertiary diamine; 2 moles of monocarboxylic acid, and an alpha, beta-unsaturated monoisocyanate, and have an alpha, beta-functionality of from about 0.8 to 2.5. The binders are rendered water soluble by neutralization with inorganic and/or organic acids. Coating compositions comprising such binders cure at low temperatures and short curing times to provide films having excellent resistance to water, chemicals, and corrosion.
