Powder coatings are applied via electrostatic spray, which creates an attraction between the powder and the substrate to be coated. The part is then heated, melting the powder and fusing it to the surface.
Powder application is best suited where excessive overspray is unavoidable, such as grill grates and gadgets.
What are the advantages of powder coatings:
- Improved transfer efficiency versus air/liquid spray
- Powder overspray can be reclaimed, drastically reducing waste
