PURPOSE: An epoxy resin curing composition is provided, to improve the weather resistance, the strength, the adhesion, the chemical resistance and the workability. CONSTITUTION: The resin curing composition comprises an epoxy resin selected from bisphenol A and bisphenol F; and a mixture of curing agents comprising 1,3-bis(aminomethyl)cyclohexane (formula 1) and isophorone diamine, in the ratio of 1:1 to 1:5 by weight. Preferably the ratio of 1,3-bis(aminomethyl)cyclohexane to isophorone diamine is 10:1 to 1:10 by weight. Optionally the composition comprises further a diluent selected from the group consisting of benzyl alcohol, furfuryl alcohol, phenyl xylyl ethane, dioctyl phthalate, dibutyl phthalate and their mixtures; polyoxypropylene amine; and/or a curing promoter selected from the group consisting of 2,4,6-tri(dimethylene aminomethyl)phenol, salts of triphenyl phosphoric acid, palm alkylamine, oleic acid amine and their mixture.
