AMIDE DIOL EXTENDED CATHODIC ELECTRODEPOSITION RESINS

摘要

An improved electrodepositable cationic resin is disclosed. Prior art electrodepositable cationic resins are formed from po- lyepoxides 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 hydrolyticall y stable and does not tend to absorb moisture.
