Powder coating is a popular industrial finish that can be used to coat a variety of materials, including metals, plastics, and ceramics. It provides a strong finish that can last for years without deteriorating and will outlast the majority of other finishes. Powder coating typically works by applying the dry powder onto an item using an electric charge. This charge keeps the powder coat as tight as possible to the exterior. Once applied, the powder coating is then melted and bonded to the metal surface by heat and pressure, creating a durable finish.

The powder itself will contain resin and pigments for coloring, as well as other potential additives that help to reach the desired levels of thickness, hardness or shine. The process used to make the powder coating stick to the surface starts by pushing the powder through a spray gun.
