PURPOSE:To provide two-pack titled composition of rapid curability, high in the heat and impact resistance of the cured products therefrom, made up of rubber- modified epoxy resin as chief component and curing agent component, i.e. a mixture consisting of polyetherpolyamine, dicyandiamide and 3-substituted phenyl-1,1- dimethylurea. CONSTITUTION:The objective composition of two-pack type made up of (A) as chief component, a rubber-modified epoxy resin prepared by the reaction between epoxy resin and carboxyl group-contg. rubbery polymer or a mixture of said modified resin with epoxy one, with the rubbery polymer content falling between 3 and 30wt% and, as curing agent component, a mixture consisting of (B) 5-30pts.wt. of polyetherpolyamine, (C) 2-20pts.wt. of dicyandiamide and (D) 0.5-5pts.wt. of 3-substituted phenyl-1,1-dimethylurea derivative each based on 100pts.wt. of the component (A).
