Powder coating is applied as a free-flowing, dry powder. Mainly used for coating of metals.
It’s a great alternative to liquid paint and a powder coating does not require a solvent to keep the binder and filler parts in a liquid suspension form.
Coating is 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.
