Abstract
A crosslinkable composition of matter is provided, which comprises first and second chain extended diepoxide resins, one or both of which are modified by reaction with hydroxy functional secondary amine and one or both of which are modified by reaction with certain secondary amine terminated or carboxy terminated butadiene acrylonitrile copolymer resin. The first resin, diene functional aminoepoxy resin, and the second resin, blocked dieneophile functional aminoepoxy resin, are co-reactive at elevated cure temperature. The diene functional aminoepoxy resin comprises the reaction product of diepoxide with amine functional diene chain extending reactant and, optionally, monofunctional end-capping reactant such as monohydroxy functional diene, and certain modifying agents. The blocked dieneophile functional aminoepoxy resin comprises the reaction product of diepoxide with amine functional blocked dieneophile chain extending reactant and, optionally, monofunctional end-capping reactant such as monohydroxy functional blocked dieneophile and certain modifying agents. The composition may further comprise crosslinking agent reactive with hydroxy functionality of the resins. The crosslinkable composition of matter is useful in coatings and other applications, especially cathodic electrocoating compositions.
