Powder Coating 102

Here’s an overview of the actual powder-coating process:

  1. Metal surfaces are thoroughly cleaned
  2. Powder coating is applied with an electrostatic (or corona) gun. Thanks to the magic of molecular physics, the electrically charged powder sticks to the metal object.
  3. The object is baked at about 400 degrees Fahrenheit, which causes the powder to melt into a uniform film.
  4. The object is cooled, turning the film into a hard coating.

Many thanks to Derek, Dave, and Juan at Portland Powder Coating for patiently educating us on the process over the years—and for producing such consistent, high quality work!
