Epoxy-Polyester (Hybrid) Powder Coating
Description
Epoxy-polyester (hybrid) powder coating is based on a combination of epoxy and polyester resins. The resin combination leads to excellent chemical resistance, mechanical performance and decorative properties. It also brings perfect leveling and glossiness. Epoxy-polyester (hybrid) powder coating is recommended for interior purposes.
Features
