Abstract

The invention relates to a coating material composition. The coating material composition contains the ingredients in percentage by mass: 30-50% of allyl-ether unitary unsaturated polyester resin with polyols, 15-25% of a polymeric unsaturated compound, 10-15% of acrylic resin, 11-16% of polyacrylic amine resin and 5-15% of an adhesion promoter. The coating material composition disclosed by the invention is suitable for being used as putty, is excellent in internal drying property during thick coating, has excellent adhesiveness to base materials and topcoat coatings and particularly has very excellent water-resistant adhesiveness to steel plate faces; the coating material composition disclosed by the invention is particularly suitable for being used as putty for repairing automobiles and railway vehicles and then can be used as putty for engineering machinery, woodworking and the like.

Description

technical field [0001] The present invention relates to a coating composition. Background technique [0002] Generally, compared with other resins, unsaturated polyol resins are inexpensive, and can be cured in a short time even at room temperature, and have excellent workability, and various excellent physical properties can be obtained by selecting the main raw material. And chemical properties, so it is widely used in various applications such as putty for automobile and vehicle repair, paint for woodworking, moldings, and sealing materials. The reactive diluent of the unsaturated polyol resin composition used in these applications has been using styrene frequently in terms of curability and physical properties. However, in recent years, environmental pollution due to its odor and toxicity has been increasing. gradually became a problem. Contents of the invention [0003] The object of the present invention is to provide a coating composition comprising an unsaturated...
