CROSSLINKABLE COMPOSITION OF MATTER - I

摘要

A novel composition of matter is provided, which comprises certain polydiene-functionalized epoxy-amine adduct and certain polydieneophile-functionalized epoxy-amine adduct, which epoxy-amine adducts are co-reactive at elevated cure temperature. The polydiene-functionalized epoxy-amine adduct comprises the reaction product of certain polyhydroxy functional epoxy-amine reactant with diene-functional mono-isocyanate reactant. The polydieneophile-functionalized epoxy-amine adduct comprises the reactoin product of certain polyhydroxy functional epoxy-amine reactant with dieneophile functional mono-isocyanate reactant. The crosslinkable compositoin of matter is useful in coating and other applications, especially cathodic electrocoating applications.
