What is Powder Coating?

Powder coating is a type of coating applied as a free-flowing, dry powder. 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. The coating is typically applied electrostatically and is then cured under heat to allow it to flow and form a “skin”. The powder may be a thermoplastic or thermoset polymer.


  • Powder coating emits zero or near zero VOCs (Volatile Organic Compounds – bad for the atmosphere and your health!)
  • Powder coating produces a much thicker, tougher coating than conventional paint.
  • Powder coated surfaces have fewer surface defects, such as sags and runs.

How does Powder Coating Work?

Powder is applied to a part through electrostatics:

  • The spray gun imparts a positive charge to powder.
  • Parts to be coated are electrically grounded.
  • The difference in electrical charge attracts powder to part.
  • Powder builds up on the part until the electric charge is fully insulated from the layer of powder.
  • Once the part is covered in powder it is placed in an oven to cure
  • The powder melts into a uniform film and cures into a hard, solid surface.
