How is Powder Coating Done?…
Powder coating is a type of dry coating applied as a free-flowing powder. The main difference between conventional liquid paint and powder coating is that the latter does not require a solvent to keep the binder and filler in a liquid suspension. Powder coating is typically applied electrostatically and cured under heat, allowing it to flow and form a durable finish.
The powder used in this process may be either a thermoplastic or a thermoset polymer. Powder coating is known for creating a hard finish that is tougher than traditional wet paints.
To Powder Coat Or Not To Powder Coat?
Almost any metal part that can be painted, can be powder coated, with a few caveats. In order to use powder, parts must be able to withstand the curing temperatures of powder.
This usually means 350°-450°F for 15-30 minutes. Parts must also be able to withstand the additional coating thickness of powder.
Powder does go on heavier than typical paint.
