Title (EN) POLYOL EXTENDED CATHODIC ELECTRODEPOSITION RESINS
(FR) RESINES D'ELECTRODEPOSITION CATHODIQUE A EXTENSION POLYOL
Abstract:
(EN) 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. The polyepoxide resin of the invention is chain extended with a monoepoxide-triol adduct which provides a resin with improved throw power and improved flow while maintaining other important characteristics of the resin.
(FR) Résine cationique d'électrodéposition améliorée. Les résines cationiques d'électrodéposition de l'art antérieur sont formées à partir de polyépoxydes dont on a prolongé la chaîne avec des polyols de polyéther ou de polyester afin d'assouplir intérieurement la résine. La chaîne de la résine polyépoxyde de l'invention est prolongée à l'aide d'un additif de monoépoxyde-triol conférant à une résine une puissance de projection ainsi qu'un écoulement améliorés tout en conservant les autres caractéristiques importantes de ladite résine.
