Now we have successfully developed and put into production four series of special products: "radiator special powder", "high-grade bicycle (electric vehicle) special powder", "pipeline anti-corrosion special powder" and "locomotive parts surface spray powder", which have been generally recognized by customers. Among them, "radiator special powder" has a market share of more than 70% in the radiator industry powder market and is a well-known radiator powder coating supplier.

Sinochem New Network News On April 20, the Paint Coating Professional Committee of the China Chemical Industry Association and the National Paint Industry Information Center released a preliminary report on the statistical results of the powder coating industry in 2023 to all member units in the industry. According to the comprehensive analysis of the sales volume of polyester resin, epoxy resin, additives, curing agent, NPG, etc. and the development of downstream industries, the sales volume of thermosetting powder coating in 2023 in China 2.484 million about 6 tons, up 8% over the previous year.

Powder coating is mainly composed of polyester resin, curing agent, pigment, filler, additives and other mixed solid powder, through electrostatic spraying, fluidized bed dip coating method and other ways to coat on the surface of the coated, and then after baking to melt leveling, curing film. Polyester resin needs to be mixed with the curing agent to react, in order to cure the film attached to the surface of the object to achieve the purpose of coating.

The powder coating market in the Asia-Pacific region is concentrated in China. In recent years, driven by a series of environmental protection policies, China's powder coating production and sales have maintained rapid growth.

According to the different types of resins used in powder coatings, powder coatings can be divided into two categories, one is thermoplastic powder coatings prepared from thermoplastic resins, and the other is thermosetting powder coatings prepared from thermosetting resins. Since thermoplastic powder coatings generally use thermoplastic resins with relatively large molecular weight, this characteristic leads to strong resin toughness, difficult crushing, high softening temperature, high melting temperature, poor leveling, and poor adhesion, which limits its application. Thermosetting powder coating is a relatively small molecular weight thermosetting resin, at a certain temperature, with the curing agent for crosslinking reaction, the formation of a network structure of macromolecular coating. Compared with thermoplastic powder coatings, thermosetting powder coatings have good performance, large output and wide application range. At present, domestic thermosetting powder coatings occupy an absolute dominant position in the powder coating market.
