Powder coating is a type of coating done mainly on metals, to create a hard finish that is tougher than conventional paint.
The powder may be a thermoplastic or thermoset polymer that is applied through electrostatic method as a free-flowing, dry powder, and then cured under heat to allow it to flow and form a skin. 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.
Powder coating is mainly used for household appliances, outdoor furniture, aluminium extrusions, drum hardware, and automobile and bicycle parts. The contractor may take the job independently from the clients or through the main building contractor appointed for the project.
