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 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 with compressed air. The tip of the spray gun is equipped with an electrode that will provide an electrostatic charge to the powder, allowing for the particles to stick closer to the surface than they would if applied using a traditional method. This charge will keep the coatings tightly bound to the exterior of the item once sprayed on. Next the part will be placed in the curing oven. Once there, the powder coating will melt and combine as the temperature reaches a heat point between 350 and 400 degrees Fahrenheit. The heat point may vary depending on the specific form of coatings used. The length of the curing process is between 10-20 minutes and will depend.
