PURPOSE:The titled resin composition free from thermal discoloration, excellent in water resistance, etc., and suitable for, e.g., coating electronic parts, obtained by mixing an epoxy resin with an aromatic amine and an acid salt of 1,8- diazabicyclo[5,4,0]undecene-7. CONSTITUTION:The purpose liquid epoxy resin composition is obtained by mixing an epoxy resin (A) (e.g., bisphenol A liquid epoxy resin) with an aromatic amine (B) (e.g., dicyanodiphenylmethane or 3,3'-diethyl-4,4'-diaminodiphenyl methane) and an acid salt (e.g., octylate or adipate) of 1,8- diazabicyclo[5,4,0]undecene-7 (C). The amount of component B added is about 1-10wt% based on component A and the amount of component C added is about 4-7wt% based on component A. It is also possible to add a reactive diluent (e.g., butyl glycidyl ether), an inorganic filler (e.g., silica), etc., to the composition.
