ABSTRACT:
Adducts of imidazolidine compounds, such as the reaction product of ethylene diamine with cyclohexanone, are provided with organic polyepoxides, especially with low molecular weight polyepoxides where the imidazolidine acts as a chain extender, and the adduct is reacted with an acid to protonate at least 50% of the amine groups in the adduct. These protonated adducts can be dispersed in water to form dispersion which cure with various curing agents. Aqueous electrocoating baths can be provided which electrodeposit at the cathode.
