(DPS) Dual-Layer Epoxy Anti-Corrosion Powder Coating/powder coating for engineering service providers
Product Introduction:
This dual-layer epoxy powder coating system is carefully formulated using special epoxy resins and functional curing agents. The base layer, like other epoxy anti-corrosion powder coatings, offers excellent anti-corrosion properties. The outer layer, while maintaining anti-corrosion properties, enhances protective performance. Compared to a three-layer PE structure, it offers a lower comprehensive anti-corrosion cost.
Product Usage:
Suitable for complex anti-corrosion environments, especially pipelines crossing through mountainous, river, and hilly areas.
Product Features:
- Excellent adhesion between the base material and the epoxy layers.
- Strong resistance to permeation and corrosion with high curing completion rate.
- High hardness of the outer coating, dense coating, scratch-resistant, and good resistance to plant root penetration.
- Excellent high-temperature cathodic disbondment resistance and superior mechanical properties.
