Powder coating is a type of coating that is applied as a dry powder and doesn't require a solvent to keep the binder and filler parts as in the case of liquid spray paint. The powder used for the process is a mixture of finely ground particles of pigment and resin and is typically applied electrostatically. It is applied to metal objects using a powder coating spray gun known as an electrostatic gun, or corona gun, after which it is then placed into a curing oven where it is heated and fused into a smooth coating.
Powder coating results in a durable and high quality finish and is commonly used for coating of metals like aluminium and steel products like auto mobile and bicycle parts and fencing. Powder coating has an attractive finish and can come in a range of colours to best suit the environment.
Powder coating is very cost effective and durable, with the coating having a high resistance to scratches and chipping. It also produces much less hazardous material which makes it more environmentally friendly in comparison to spray painting, and powder coated products can even be recycled.
