Powder coating is a type of coating that is applied as a free-flowing, dry powder.
The main difference between a conventional liquid paint and a powder coating is that the powder coating does not require a
solvent to keep the binder and filler parts in a liquid suspension form.
The coating is typically applied electrostatically and is then cured under heat to allow it to flow and form a "skin". The powder may be a
thermoplastic or a
thermoset polymer. It is usually used to create a hard finish that is tougher than conventional paint. Powder coating is mainly used for coating of
metals, such as
"whiteware", aluminium
extrusions, and
automobile and
bicycle parts
