Normally, when you paint something, the pigment is dissolved in a solvent. You paint the mixture on, and the solvent evaporates and leaves behind the pigment. For powder coating the pigment is powdered. The part is charged with static electricity and then sprayed with the powder, which sticks to it in a uniform layer. Then the part is baked and the pigment melts into a coating. The advantage of this is first that it's cheaper because you don't waste as much pigment, and also it's better for the environment because you don't have all that solvent going into the atmosphere.
The process is an efficient and highly effective method of coating a wide variety of consumer products ranging from domestic appliances to garden furniture.
