Powder Coating is a term that is, at times, used incorrectly to describe a specific coating. Powder coating is a form in which many different coatings can be conveyed and deposited onto a surface.
Powder coating types vary from very high performance Teflon® and other fluoropolymers coatings down to very simple epoxies and urethanes.
The most common powder coating is TGIC or Hybrid coatings that are a combination of epoxy and polyester. These are used to provide UV and corrosion resistance on items such as outdoor furniture whereas fluoropolymer powder coatings such as PFA (perfluoroalkoxy) provide a high performance inert finish that can be used in a wide variety of specialty applications.
Powder coatings provide higher transfer efficiency and the ability to easily coat large surfaces effectively.
Key Characteristics of Powder Coatings:
- Generally Durable and Tough
- Baked finish conducive to high volume production
- Electrostatic or Fluid Bed application
- Relatively low cost
- Available in Almost Any Color
