since 2004, China's powder coating industry has continued to maintain rapid development. After 2003, the output of powder coating ranked first in the world, making this "world first" hat wear more firmly

China's powder coating and coating industry has developed with the rise of domestic household appliance industry since the reform and opening up. After more than 20 years of development, it has made great progress from scratch, from small to large. The development speed of powder coating industry has accelerated since last year, far exceeding the average development speed of the national coating industry. In 2003, China's paint production exceeded 2million tons for the first time, with an increase of 11%; In 2003, the output of thermosetting powder coatings in China reached 340000 tons, an increase of 25%, more than twice the growth rate of the national coating output; In 2004, the ductility of thermosetting powder coatings reached 410000 tons, with an annual growth rate of 20%. China has become a real power producer of powder coatings

since the reform and opening up, from the production of raw materials, pulverizing equipment, pulverizing technology to powder coating equipment and construction applications, the majority of enterprises have greatly improved the production technology and product quality of powder coatings without pollution to the environment through research, introduction of foreign technology, and further digestion and absorption. The raw materials of powder coatings are basically localized, and the special epoxy resin and polyester resin production plants have been put into operation, and the quality has been continuously improved; The localization of pure polyester curing agent (TGIC, T105) and matting curing agent has greatly reduced the cost of powder coating; The quality of leveling agents and additives has also been greatly improved, which has promoted the development of powder coatings in China. The milling equipment has basically met the needs of domestic powder coating production, from the initial single screw extruder to the current twin-screw and multi screw extruder, from the low screw speed level to the high speed level, from the universal crusher to the ACM mill; The powder spraying equipment has met the powder construction requirements, forming a group of manufacturers specializing in the production of powder electrostatic spraying equipment. From the introduction of foreign coating lines to the localization of the current spraying production line, it has laid the foundation for the rapid development of powder coatings

at present, in terms of geographical distribution, China's powder coating industry is mainly distributed in the Pearl River Delta and the Yangtze River Delta, which account for about 80% of the country's powder coating output; The second is the Beijing Tianjin area, accounting for about 10%; The rest of the country accounts for only about 10%. This distribution is basically consistent with the distribution of epoxy resin enterprises in China. For example, the Yangtze River Delta has a domestic leading enterprise, Bluestar new material Wuxi resin factory, Dow Chemical production base, etc

powder coating is a formula material based on resin, combined with curing agent, pigment, filler and other raw materials. It is coated on the surface of the substrate by electrostatic spraying or other methods, giving the coated metal substrate good appearance and durability. Therefore, the field of powder coating and coating technology is very wide. The base materials of powder coatings are mainly thermosetting resins (such as epoxy resin and polyester resin) and thermoplastic resins (such as PVC and nylon 11). Thermosetting powder coatings are mainly epoxy polyester mixed type, pure polyester type and pure epoxy type. China's powder coatings are mainly thermosetting, and the output of thermoplastic powder coatings is very small, mainly PVC powder. According to the industry data statistics of the coating professional committee in 2003, the output of thermoplastic powder coatings is only 9000 tons. Taking thermosetting resin as the main material and epoxy resin as the main base material is an important feature of China's powder coating industry
