ABSTRACT:
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 amide diol which gives a resin which is hydrolytically stable and does not tend to absorb moisture.
