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.
