Powder coating is mainly composed of resin, curing agent, pigment, filler, additives and other mixed solid powder, by electrostatic spraying, fluidized bed dip coating method and other methods coated on the surface of the coated, and then baked to melt the leveling, curing film. Because it does not contain any organic solvent, no pollution, high utilization rate, low energy consumption and simple process, powder coating has become a recognized "4E" (high efficiency, energy saving, environmental protection and economic) coating. In addition, powder coating itself has the advantages of high mechanical properties, excellent chemical resistance, corrosion resistance and labor intensity reduction. Therefore, powder coating has been paid attention to by all countries since its introduction, become the new darling of the paint market.

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 large relative molecular mass, this characteristic leads to strong resin toughness, difficulty in crushing, high softening temperature, high melting temperature, poor leveling, and poor adhesion, which limits its application. Thermosetting powder coating is the use of small relative molecular mass of thermosetting resin, at a certain temperature, and 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.

Powder coating is mainly composed of resin, curing agent, pigment, filler, additives and other mixed solid powder, by electrostatic spraying, fluidized bed dip coating method and other methods coated on the surface of the coated, and then baked to melt the leveling, curing film. The upstream of the powder coating industry chain is raw materials, including resins, pigments, solvents and additives, etc. The midstream is powder coating products, which are divided into thermoplastic powder coatings and thermosetting powder coatings according to the type of resin used. At present, the domestic thermosetting powder coatings occupy an absolute dominant position in the powder coating market; the downstream is the application field of powder coatings, powder coatings are widely used in building materials, household appliances, furniture, 3C and automobiles because of their advantages such as no organic solvents, safe production and construction, recyclable at the end of over-spraying, easy automation of coating and excellent coating performance.

The initial stage of the development of China's powder coating industry began in the 1970 s. The former Coating Industry Research Institute of the Ministry of Chemical Industry has successively developed decorative, anti-corrosion, low-temperature curing epoxy resin powder coatings, polyester resin powder coatings and other products, and in Shenyang, Chengdu, Jiangsu and other places for trial production;

In 1984, China's home appliance industry, led by the industrial sector began to flourish. With the continuous expansion of the industrial application of powder coatings, domestic scientific research and production units, in addition to investing in the development of new products to meet market demand, began to introduce advanced technology and manufacturing equipment for powder coatings from abroad, thus opening the prelude to the introduction and localization of technology in China's powder coating industry;

In the 1990 s, Herberz of Germany and AkzoNobel of the Netherlands entered China and quickly became the largest powder coating manufacturer in China; at the same time, the powder coating led by Hangzhou Sino-French, Anhui Excalibur, Zhejiang Tiansong, and Guangzhou Qingtian The rapid development of polyester manufacturers has driven the development of China's powder coating industry;

At the beginning of the 21st century, my country's powder coating industry began to develop rapidly; by the end of 2021, there were more than 10,000 powder coating production equipment manufacturers in the country. While the products meet domestic demand, they have also been widely recognized by overseas markets, and the international market share continues to increase.
