Powder coating is harmless, high efficiency, resource saving and environmental protection. Different from general coating, powder coating exists in the state of micro powder. Because it does not need solvent, it is called powder coating. Although there are not as many kinds of powder coatings as solvent coatings, there are also many polymer resins that can be used as powder coatings. In general, it can be divided into two categories: outdoor and indoor.
1. Outdoor powder coating
Pure polyester powder coating
Pure polyester powder coating is a kind of powder coating specially designed for outdoor weather resistance. It has good weather resistance and color stability, and is widely used in outdoor building materials machines. This product is rich and colorful in variety and color. It has bright, flat, matte, sand grain and other products. It can also be designed according to customers' requirements. It is applied to aluminum profiles for construction, automobiles, motorcycles, new energy vehicles, agricultural machinery, engineering machinery, road barriers, external fitness equipment and competition equipment, as well as metal surfaces with weather resistance requirements, etc.
2. Indoor powder coating
Epoxy polyester powder coating
Epoxy polyester powder coating is made of epoxy resin and polyester resin. It has good decoration and thermal stability. It is generally not suitable for outdoor or places with weather resistance requirements. This product is rich in varieties and colors, including: highlight, matte, matte, pattern, wrinkle, metal and other color products. It is applied to all kinds of hardware accessories, household appliances and medical equipment, automobiles, motorcycles, new energy vehicles, agricultural machinery, engineering machinery accessories, chassis cabinets, various furniture, etc. This product is not recommended for outdoor weather resistant products.
Pure epoxy powder coating
High molecular weight epoxy resin and curing agent are used as the main base material of pure epoxy powder coating. Excellent adhesion, impact resistance, surface hardness, toughness, adhesion and other mechanical properties. High gloss, high leveling, good coating effect, good chemical resistance and corrosion resistance, good electrical insulation, high baking temperature, too long time, easy to turn yellow, can not be used for outdoor products. It is applied to steel bars, water pipes, valves, steel cylinders, agricultural machinery, steel structures, electromechanical equipment, instrument casings, motor rotors, as well as household, anti-theft doors, industrial equipment, fitness equipment, etc.
