Acrylic resin paint (code B) is a new variety of paint that has developed very rapidly since the 1950s. Acrylic paints are composed of resins made by polymerizing acrylic and methacrylate esters, as well as other ethylenic monomers. By choosing different resin structures, different formulations, production processes, solvents and additives, two types of coatings can be made: thermoplastic (volatile) and thermosetting (cross-linked curing). They can be divided into solvent-based, water-soluble, water-dispersed, non-water-dispersed, powder and solvent-free series of acrylic resin coatings with different performances and multiple uses.
The main absorption peak of the acrylic resin made by copolymerization of acrylic acid and methacrylate monomer is outside the solar spectrum range, so the acrylic resin coating made with it has excellent light aging resistance and weather resistance. At the same time, the acrylic modified resin coating has good acid, alkali, salt and grease resistance, heat resistance, corrosion resistance and "three-proof" performance, strong adhesion, hardness and good flexibility. Due to its good light resistance and outdoor aging resistance, acrylic resin coatings are widely used as car paints. Acrylic polyurethane coatings are used as military and civilian aircraft coatings. In addition, it is widely used in the appearance of household appliances such as washing machines and refrigerators in light industry, instruments and meters, metal furniture, aluminum products, plastic products, interior and exterior walls of buildings, textiles, paper industry and coil industry. Coating the surface of tinplate with thermosetting acrylic resin paint not only makes the film bright and beautiful, but also has good water resistance, heat resistance and grease resistance. layers and corrosion-resistant coatings.
Over the past 20 years, foreign acrylic resin coatings have been greatly developed in terms of output and variety. The output of acrylic resin coatings in the United States has accounted for more than 20% of the total output of coatings, and the proportion of new types of coatings such as water-based, powder, high-solid, light-curing and electron beam curing is increasing. It can be predicted that acrylic resin coatings are a very promising category in CHINA.
