PURPOSE: To obtain a silane coupling agent which is readily soluble in water and with which a molded glass-fiber-reinforced epoxy resin article having excellent soldering heat resistance can be produced in a short time, by using a specific aminosilane compound or a salt thereof. CONSTITUTION: An aminosilane compound, N-(P-trimethyl)-γ- aminopropyltriethoxysilane hydrochloride represented by the formula (wherein R<1> is H, methyl, or ethyl; (m) is 0-3; (n) is 1-6; and R<2> is a 1-10C alkyl) is obtained, for example, by introducing 1.0mol ofγ-aminopropyltriethoxysilane as a feedstock aminosilane into a reaction vessel, heating it to 60-80 deg.C, dropping 1.0mol ofα-chloro-p-xylene as a halide thereinto, and reacting the mixture under stirring at 60-80 deg.C for 16hr. Methanol is added to this hydrochloride. Glass fibers are immersed in the resultant methanol solution as a surface treatment agent and then dried at 100-120 deg.C to obtain surface-treated glass fibers, which are impregnated with an epoxy resin to obtain a molded glass-fiber- reinforced epoxy resin.
