Because of its high coating efficiency and no pollution, thermoplastic powder coating is still of great significance to develop new epoxy powder coating, especially new epoxy resin. The use of silicone resin can make the heat resistance function of powder coating significantly improved, can meet the long-term use in the environment, and the coating has outstanding adhesion and impact resistance and inevitable flexibility, can be used as the idea and exhaust pipe heat resistance coating. The defect is the low mechanical strength and the poor adhesion to the matrix. With the rapid development of wild building materials, home appliances goods, as well as the increasing number of various vehicles, the demand for paint goods is continuing to add, whether the number of types or functional requirements, have put forward a lot of to paint industry, and raw material manufacturers to deal with the topic.
Epoxy powder coating is the most important, but also the best function of a kind, with its excellent adhesion, flexibility, as well as outstanding erosion resistance and corrosion life, is widely loved and expected by the market. The determination of gelatinization time of powder coating belongs from low temperature curing powder coating to energy-saving and environmental protection products, which is the inevitable trend of powder coating, but it does not constitute the trend of key points and joint research. Therefore, China still has a long way to go to carry out energy-saving powder coating. They are stored at room temperature, through electrostatic spraying, conflict spraying (thermosetting method), or fluidized bed immersion (thermoplastic method), reheating baking melting curing, so that the permanent film with flat light, to the intention of decoration and erosion prevention. This situation not only reflects the gap between Chinese coatings and the United States in skills, teaching, legislation, norms, scientific research and other aspects, but also reflects the Chinese government in scientific and technological innovation investment in the system, but also reflects the planning, strength, location, discourse power weight is not heavy. Polyethylene powder coating has excellent erosion protection, chemical resistance and excellent electrical insulation and ultraviolet radiation resistance. It can be used in chemical tank tank, impeller, pump, pipe inner wall, outer shell, metal plate, refrigerator inner net plate, auto parts, etc.
