Performance Characteristics Of Powder Coating (part 1)

Powder Coating not only have the good appearance characteristics of powder coating but good performance characteristics.
advanced Durability.
    Recent research and testing shows that specially formulated polyester powders that provide even greater weatherability than achievable in previous years, and it shows greater success in long-term Florida exposure testing. TGIC-based powders are being used on outdoor stadium seating and other exterior applications that were previously susceptible to degradation from ultraviolet rays. Powder with polytetrafluoroethylene (Teflon) additives for increased resistance to abrasion also benefit Light poles, lawn furniture, shopping carts, and shelving.
Electroconductive & Electrodissipative. 
    Electronic components makers sometimes use electroconductive and electrodissipative powder coatings, which provide electrostatic discharge protection of the components, critical during the manufacture, testing and transport of electronic goods. The most common colors for these special powders are black and charcoal, but lighter colors are also available.
Good performance in Heat-Sensitive Substrates. 
nylon coating
    In recent years, ongoing research and development has been devoted to formulating powders that can cure at lower temperatures as low as 200°F, without losing good durability or quality. These powders can be used on temperature-sensitive materials, as well as on massive parts that require enormous amounts of energy with other curing systems. More wood materials such as particle board and fiberboard can now benefit from a powder coated finish. This technology has been used in office furniture, kitchen cabinets, and ready-to-assemble furniture for homeowners in our daily life. In-roads have also been made in perfecting powder coating for hardwoods.
    In addition to successfully penetrating the market for wood products, powder has proven to be an effective finishing choice for other heat sensitive substrates such as some plastic parts and products, using nylon, polycarbonates, polyethylene and other materials. Plastic products now powder coated include office furniture, handles and knobs for major appliances, automotive parts and trim, medical equipment, and seating for buses, trains, and stadiums. The coating is effective in covering imperfections in the plastic molding process.
