Advantages of Powder Coating

Powder coating is applied as a free-flowing, dry powder. It is different from conventional liquid paint in that it does not require a solvent to keep the filler & binder parts in a liquid suspension form. Powder coating is usually applied electro statically, and is cured under heat.

The powder will be either a thermoplastic or a thermostat polymer, and is usually used to create hard finishes that are tougher than conventional paint. It is used mainly for coating metals, like white ware, aluminum extrusions, and automobile or bicycle parts.

Advantages of Powder Coating over Liquid Coatings:

1. Powder coatings emit zero or near zero volatile organic compounds (VOC).
2. Powder coatings can produce much thicker coatings than conventional liquid coatings without running or sagging.
3. Powder coating overspray can be recycled and thus it is possible to achieve nearly 100% use of the coating.
4. Powder coating production lines produce less hazardous waste than conventional liquid coatings.
5. Capital equipment and operating costs for a powder line are generally less than for conventional liquid lines.
6. Powder coated items generally have fewer appearance differences between horizontally coated surfaces and vertically coated surfaces than liquid items.
7. A wide range of specialty effects is easily accomplished which would be impossible to achieve with other coating processes.
