What is Powder Coating?

Powder coating is a type of coating that is applied as a free-flowing, dry powder. Unlike conventional liquid paint which is delivered via an evaporating solvent, powder coating is typically applied electrostatically and then cured under heat. 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. Powder coating is mainly used for coating of metals, such as household appliances, aluminium extrusions, drum hardware, automobile, motorcycle, and bicycle parts. Newer technologies allow other materials, such as MDF (medium-density fibreboard), to be powder coated using different methods.

Powder coating is dry finishing process and several companies are preferring powder coating owing to its durable finish and high quality. It is an excellent alternative for conventional liquid paint since it eliminates the need for a solvent. Electrostatically applied, powder coating creates a hard finish than traditional paints and mainly used for coating of metals and other hardware. Powder coating provides corrosion protection, excellent outdoor durability, and high-temperature performance with a wide range of specialty effects which is otherwise not easily achievable through other coating methods.

The powder coating process was invented around 1945 by Daniel Gustin and received US Patent 2538562 in 1945.This process puts a coating on an item electrostatically, which is then cured by heat. The finish is harder and tougher than conventional paint. The process is useful for coatings on metal used in many household appliances, aluminum products and automotive parts.

The Powder coating market is driven by high demand for various equipment, file drawers, computer cabinets, laptop computers, cell phones, and electronic components. Texture variation, color & coating thicknesses in paint industries would play a key role in keeping the market trend upwards. The increasing use of powder coatings for aluminum extrusion and electrical fixtures will further boom the market. Government schemes and awareness for eco-friendly and economical products will stimulate demand over the forecast period.
