Powder coating is an advanced method of applying a decorative and protective finish to a wide range of materials and products 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.

Today, powder coatings are primarily being used in home appliances, automotive, building, oil and gas piping, machinery, outdoor products and also non-metal products. Powder coating is the fastest growing finishing technology, representing over 10% of all industrial finishing applications. The global powder coating market was estimated to 70.6 billion US$ in 2000.
