To provide a coating composition for anti-corrosion, which has adhesive property, corrosion resistance, and impact resistance which are comparable to the coating workability of a tar-based coating composition for anti-corrosion, and to provide a coating base agent used for the coating composition.
This coating base agent comprising 100 pts.wt. of a main agent comprising a polyol resin containing two or more alcoholic hydroxy groups in the molecule or an epoxy resin containing two or more epoxy groups in the molecule, 5 to 200 pts.wt. of bituminous coal having an ash content of ≤10 wt.% and a water content of ≤3 wt.% after dried, 5 to 200 pts.wt. of an aromatic oligomer, and 20 to 400 pts.wt. of an aromatic hydrocarbon-based solvent. The urethane resin coating for the anticorrosion, comprising the coating base agent consisting mainly of the polyol resin and an isocyanate-based curing agent so that the molar ratio of the isocyanate groups of the curing agent to the hydroxy groups of the coating base agent is 0.2 to 2.0. The epoxy resin coating for the anticorrosion, comprising the coating base agent consisting mainly of the epoxy resin and an amine-based curing agent so that the molar ratio of the amino groups of the curing agent to the epoxy groups of the coating base agent is 0.2 to 2.0.
