Powder coating, sometimes referred to as “dry powder paint” is a completely solvent free system that uses a combination of microscopic organic and inorganic pigment solids, fillers, resins and hardeners that are applied by spraying a dynamic mixture of air & powder via a specially designed, electrically charged nozzle onto an electrically grounded target substrate.
This electrostatic differential between the powder and the part causes the powder suspension to “cling” to any exposed part surfaces.
These parts are then placed into a curing oven that reflows (melts) the microscopic powder into a thixotropic fluid that then cures into a physically durable and aesthetically attractive finish.
Typically, powder coating is used for coating of metals such as aluminum, steel and other alloys. However, powder coating can also coat high temperature resistant plastics and substrates.
