Powder coating is the youngest of the surface finishing techniques that is still in use today. It was first used in 1967 in Australia by Allan Davies.
Powder coating is the simple technique of applying dry paint to a part such as metal or plastic, and after the final coating is the same as a finished 2-coat wet paint job. Powder coating can be applied in two ways; either by lowering an item into a bed of powder which may or may not be electrically charged, or the powder paint is electrically charged and sprayed onto the part. After being coating with dry paint, the part is placed in an oven and the powder particles melt and combine to form a permanent layer of paint.
