The Development of Coating Industry of The ext 10 Years
2015.03.06 09:19research. This research mainly is to improve the performance of the coating. (2) the construction of the application of research. The United States, Japan, Germany and other countries have produced metal rust, paint, popular in the market.
Thermoplastic commonly used acrylic polymer emulsion finishing, acrylic copolymer or polyurethane dispersions, through large molecular weight of particle coalescence and curing film. Latex particle coalescence of sex to the performance of the latex film. In recent years, focus on the development of strong adhesion makings and fast drying finishing, as well as the development of hybrid emulsion. Generally water-based polymer emulsion on hydrophobic substrate, poor adhesion, to improve the latex adhesion, must pay attention to emulsion polymer and formula design, make it as far as possible close to the surface of the substrate, and carefully select the appropriate coalescer, reduce the surface tension of water, to adapt to the substrate. New development of polymer emulsion coalescence easily, less dosage of coalescer can very good film-forming, now is widely used in furniture, machine and other plastic products.
Newly developed emulsion mixture made up the water dilute alkyd/rigid thermoplastic emulsion their shortcomings, through the formula design, has solved the mixed problem of poor solubility and stability. Waterborne polyurethane coating is in recent years the rapid development of waterborne coatings, besides general polyurethane coating of excellent properties such as high strength, wear resistance, and to the environment pollution-free, poisoning and little risk of fire. Due to the existence of ammonia ester in aqueous polyurethane resin molecular keys, so the flexibility of waterborne polyurethane coating, mechanical strength, wear resistance, chemical resistance and durability is very excellent, such as Europe, America, the average daily as varieties and develop the modern coatings.
Powder coating is developing rapidly
In the coating industry, belong to one of the fastest growing type of powder coatings. Due to the serious air pollution in the world, the environmental protection laws and regulations to control the pollution is becoming more and more strict, to develop pollution-free, provincial resources paint variety. Therefore, solvent-free, protective and decorative comprehensive performance of powder coatings, and because of its unique economic and social benefits gained rapid development.
