摘要： Disclosed is an aqueous organic-inorganic complex coating composition for a thin film which has a good curing characteristic at a low temperature and various good characteristics. The organic-inorganic complex coating composition for a steel sheet comprises about 100 weight parts of a water-soluble acrylic or vinyl modified organic high polymer resin, about 5 to 100 weight parts of a silica-based inorganic compound and about 1 to 50 weight parts of a curing agent based on the solid content of the water-soluble organic high polymer resin. The thin coating layer formed on the steel sheet using the organic-inorganic complex coating composition of the present invention has a good curing characteristic at a low temperature. Moreover, alkaline-resistance, corrosion-resistance, adhesiveness to the material, electrodeposition coating characteristic, anti-powdering characteristic, continuous weldability, and work efficiency of the coating are good. Moreover, since the coating composition of the present invention includes the acrylic or vinyl modified epoxy resin as a main component, an energy conservation problem and an environmental pollution problem can be solved. Further, working stability is good and the probability of a fire is decreased.
