Design Considerations

  • The added thickness of the coated layer makes it necessary to plug and mask holes or other tolerance-tight surfaces that will play a functional role.

  • Pricing of powder coats can be inconsistent between colors, finishes and part geometry.

  • Most polymers used for powder coating have poor electrical conductivity.
