Powder coating is a type of dry coating, which is applied as a free-flowing, dry powder. The main difference between a conventional liquid paint and a powder coating is that the powder coating does not require a solvent to keep the binder and filler parts in a liquid suspension form.

The coating is typically applied electrostatically and is then cured under heat to allow it to flow and form a "skin." The powder may be a thermoplastic or a thermoset polymer. It is usually used to create a hard finish that is tougher than conventional paint.

There are several advantages of powder coating over conventional liquid coatings:

Powder coatings emit zero or near zero volatile organic compounds (VOC). Powder coatings can produce much thicker coatings than conventional liquid coatings without running or sagging.

Powder coating overspray can be recycled and thus it is possible to achieve nearly 100% use of the coating. Powder coating production produces less hazardous waste than conventional liquid coatings.

Powder coated items generally have fewer appearance differences between horizontally coated surfaces and vertically coated surfaces than liquid coated items. Powder coating is an advanced method of applying a decorative and protective finish to a wide range of materials and products, including steel doors, that are used by both industries and consumers.

The powder used for the process is a mixture of finely ground particles of pigment and resin, which is sprayed onto a surface to be coated. The charged powder particles adhere to the electrically grounded surfaces until heated and fused into a smooth coating in a curing oven. The result is a uniform, durable, high-quality, and attractive finish. Powder coating is the fastest-growing finishing technology.
