Zinc-rich powder coating
Introduction
This series of products is based on saturated carboxyl polyester resin and TGIC curing agent as the main base material. It is a thermosetting powder coating with excellent weather resistance designed for outdoor materials used in construction. It has a weather resistance of 10 to 15 years.
This series of products is a professional anti-corrosion powder coating, which is designed to provide high-quality anti-corrosion protection for steel structure materials under harsh climate and environmental conditions. It is suitable for outdoor steel structures such as metal components, gas tanks, bridges, and street facilities. It can be used as a single-layer anti-corrosion coating independently or as a supporting anti-corrosion primer.
