Product name: Pure epoxy powder coating
Product description:
Powder coating is one of the polymer synthetic materials, it has energy saving, low pollution, high efficiency and so on. Not only a film, painting high efficiency, and the surface coating corrosion resistance, high mechanical strength. The company's existing thermosetting powder coating epoxy, epoxy / polyester, polyester, polyurethane and other fourteen series, thousands of specifications products, and a variety of special-purpose powder coatings such as high decorative texture powder coating, weather Type, art type, insulation type, pattern type, all kinds of metal surface effects and other types.
The powder coating is mainly used in construction, decoration, household appliances, metal furniture, instrumentation, highway guardrail, cars and spare parts, fitness equipment, painting and other industries.
General introduction:
It is made of epoxy resin as the main raw material and has excellent chemical resistance and mechanical properties. It is suitable for the coating of metal products with high corrosion resistance, electrical insulation and flexibility. Generally do not recommend directly to the surface coating of various outdoor supplies.
Product Series:
Can provide standard and low temperature curing powder coating products. Can be made of gloss (more than 80%), half-gloss(50-80%), semi-gloss (20-50%) and matt (20%) products. (According to the needs of users control gloss)
Powder physical properties:
proportion(g/cm3, 25℃):1.4-1.7
Distribution of particle size: 100% less than 60um (can be adjusted according to special requirements of coating)
Curing conditions:
