Definition - What does Powder Coating mean?
Powder coating is coating that is applied as dry powder or free flowing. It is completely different from traditional liquid paint, as it requires a solvent for the filler and binder parts to form in a suspending liquid.
It is mainly used to coat metals, like aluminum extrusions, household appliances, bicycle and automobile parts and drum hardware.
