Background
Powder coatings represent a rapidly growing area in the overall coating technology. Because the VOC emission is almost zero, the rapid development of the VOC is driven by the environmental protection requirement.

Metals which are exposed to air for a long time, in contact with oxygen and water vapor, are rapidly oxidized, i.e., rusted, and their strength and other properties are greatly reduced, for example, metallic iron. The existing powder coating is used for corrosion prevention of metal, but after the existing powder coating is sprayed, oxygen and water vapor in the air can still contact with the metal through micropores due to poor compactness of a coating layer, so that the metal is oxidized. Once the metal of the inner layer is oxidized, the coating of the outer layer is stripped, and a chain reaction is formed until the coating is completely stripped and the metal is completely oxidized.
