Epoxy Powder Coatings
As a classic type of power coating, epoxy powder coatings were the first thermosetting system to become commercially available and are still widely used today. Epoxy coatings are used primarily as functional coatings for substrate protection where inherent toughness, corrosion resistance, flexibility, and adhesion are required. The primary limitation of epoxy-based coatings is poor weatherability.
Typical applications include pipe coatings, electric meters, metal furniture, shelving, electrical parts, refrigerator liners, dryer drums, and high voltage switchgear.
Advantages
Excellent chemical resistance
Gives low gloss, matte finishes
Smooth coatings
Good corrosion resistance
Good mechanical properties
F-5H pencil hardness
Excellent adhesion to substrate
Excellent electrical properties
Very good abrasion resistance
Disadvantages
Chalks when exposed to UV
Poor UV resistance
