FA-0366 URETHANE DIOL EXTENDED CATHODIC ELECTRODEPOSITION RESINS ABSTRACT OF THE DISCLOSURE An improved electrodepositable cationic resin is disclosed. Prior art electrodepositable cationic resins are formed from polyepoxides which are chain extended with polyether or polyester polyols to internally flexibilize the resin. Our polyepoxide resin is chain extended with urethane diol which gives a resin with improved throw power and coatings with better chip resistance while maintaining other important resin characteristics.
