A process for achieving the acceleration of the curing of epoxy resins characterized in that 100 parts by weight of an anhydrous bis-phenol A diglycidyl ether, having equivalent epoxide weights between 100 and 500 and containing 0.015 to 0.15 parts by weight of sodium in the form of alcoholate, receive the addition of approximately equivalent amounts of hardener of carboxylic acid anhydride, the latter reacting with sodium forming sodium salt, which, in turn, facilitates the reaction of the hardener activated with the groups epoxides of diglycidyl ether of bis-phenol A.
