ABSTRACT:
Novel, chain-extended adducts formed from reacting high molecular weight polyepoxides and polyester polyols containing at least two alcoholic, primary hydroxyls per molecule are disclosed. The chain-extended polyepoxides are adducted with a secondary amine and made dispersible in water with acid. The water-dispersed resins can be applied to a wide variety of substrates by cationic electrodeposition. When compared to resins which are not chain extended, the resins of the invention have higher rupture voltages, improved film-forming properties and deposit as films with improved flexibility.
