ABSTRACT:
Adducts of oxazolidine compounds, such as the reaction product of monoethanol amine with cyclohexanone, are adducted with an organic polyepoxide 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 dispersions which cure with various curing agents. When all the epoxy groups are consumed by reaction with the oxazolidine, aqueous electrocoating baths can be formulated which may contain aminoplast resin or phenoplast curing agents.
