1.A coating can get thicker coatings, for example, applying a coating of 100 ~ 300μm, with an ordinary solvent coating, the coating is about 4 to 6 times, while the powder coatings can be achieved once the thickness . Corrosion-resistant properties of the coating is very good. 2.Solvent-free powder coating, no wastes pollution, and improve the working conditions of health. 3.Using new technology such as electrostatic spraying powder, high efficiency, suitable for automatic coating lines, powder utilization, recyclable. 4.In addition to thermosetting epoxy, polyester, acrylic, there are a large number of thermoplastic resin can be used as powder coatings resistant, such as polyethylene, polypropylene, polystyrene, fluorinated polyether, nylon, polycarbonate and various types of fluorine-containing resin. Powder coating start for the protection and electrical edge, along with the development of technology, has been widely used in the automotive industry, electrical insulation, corrosion-resistant chemical pumps, valves, cylinders, pipes outdoors steel components, steel furniture, castings and other surfaces painting. China since the beginning of the sixties experimental study powder coating, and has been applied in production. Development has been widely be used.
