PURPOSE: An environment-friendly epoxy primer paint composition is provided to reduce the usage amount of a solvent, and to be suitable for the VOC content limit standard. CONSTITUTION: A two-liquid type primer paint composition contains a primer main resin and amine curing agent containing 10-30 parts by weight of denatured bisphenol A type epoxy resin in a low viscosity liquid form, and 0.5-5.5 parts by weight of bisphenol A type epoxy resin in a high viscosity liquid form (primer main resin : amine curing agent = 100 : 30-40). The denatured bisphenol A type epoxy resin in the low viscosity liquid form has the viscosity of 1,000-9,000 cps at room temperature, and the epoxy equivalent weight (EEW) of 100-400. The bisphenol A type epoxy resin in the high viscosity liquid form has the viscosity of 11,500-13,500 cps, and the epoxy equivalent weight of 230-280.
