Abstract
A curable epoxide composition consists essentially of curable epoxides, dicyandiamide as a curing agent in an amount less than needed to fully cure the epoxides, an imidazole in an amount exceeding that needed as a catalyst and capable of curing the epoxides in combination with the dicyandiamide, a reactivity controller for the imidazole to reduce the curing speed, and a solvent. The use of undesirable solvents such as DMF is reduced. A glass transition temperature greater than 135.degree. C. is obtained in the cured composition and is maximized by balancing the amounts of dicyandiamide, the imidazole, and the reactivity controller.
