PURPOSE: An epoxy ester-modified moisture-curable urethane paint composition is provided to offer an excellent physical property chemically and mechanically including the corrosion resistance, maintain an excellent adhesive force, an abrasivity and durability. CONSTITUTION: An epoxy ester -modified moisture-curable urethane paint composition comprises a flexible epoxy ester resin in which number average molecular weight is 500-20,000 and a moisture-curable urethane resin in which number average molecular weight is 500-2,000. The flexible epoxy ester resin comprises 30-45 % of whey and acid value is 5 or less. The flexible epoxy ester resin is obtained from the epoxy resin in which epoxy equivalent is 300-3,500 and a solid content is 55% or less; and C8-20 fatty acid. The urethane paint composition further includes more than one kind which is selected from a reaction catalyst, a hardening accelerator, a co solvent and solvent. |
