Powder coating is different from the general coating, which is the state of the fine powder. Because of no use of solvent, it is called a powder coating. The main features of the powder coating are: it is harmless, high efficiency, saving resources and environmental protection features.

It has two major categories: thermoplastic powder coating and thermosetting powder coating.

Thermoplastic powder coating are composed of thermoplastic resin, pigment, filler, plasticizer and stabilizer. Thermoplastic powder coating include polyethylene, polypropylene, polyester, polyvinyl chloride, chlorinated polyether, polyamide, cellulose, polyester.

Thermosetting powder coating are made of thermosetting resins, curing agents, pigments, fillers and additives. Thermosetting powder coating include: epoxy resin, polyester, acrylic resin system.

Disadvantages: the edge angle of the powder is not uniform, after curing film defects difficult to cover up, curing conditions.

Classification standard, the name of various types of powder on the market is uneven. According to the properties of the film forming material is divided into two categories: thermoplastic powder coating and thermosetting powder coating. Or the appearance of film forming material is divided into: extinction type, high light type, art type, etc.. You can also press the use of the environment is divided into indoor and outdoor two categories.

The biggest growth areas of powder coating market in China are: shipbuilding industry and pipeline industry. The problem is that the impact resistance and moisture absorption to be improved and improved, the researchers put the main focus on the use of a variety of base material modification. Domestic production pipeline anticorrosion epoxy powder coating in the storage stability and coating construction, compared with foreign high-quality products, there is a certain gap.

Due to the development of the preparation technology of foreign automobile powder coating, the coating of automobile cover, wood and plastic is the most active potential market. The automotive industry will be the growth momentum of the powder coating market in Greece, Turkey and Eastern Europe, which is a major consumer of the consumer market. The market potential of the Asia Pacific region has been considered to be the fastest growing region in the world.
