3-Layer Polyethylene (FPE) Anti-Corrosion Epoxy Powder Coating
Product Introduction:
This product is formulated using epoxy resin and phenolic epoxy resin, designed and manufactured according to GB/T 23257-2009. It features high reactivity, strong adhesion, high cross-link density, and excellent resistance to chemicals, cathodic disbondment, and impact.
Product Usage:
Suitable for anti-corrosion coatings on various oil and gas pipelines.
Product Features:
- Excellent adhesion to the substrate.
- Appropriate gel time and interfacial properties, easily fusing with the intermediate adhesive layer to form a cohesive unit.
- Provides protection over a wide temperature range, ensuring long-term corrosion resistance.
- Superior high-temperature cathodic disbondment resistance.
- High coverage area and transfer efficiency.
- Low melting temperature, high reactivity, and high curing completion rate, with good mechanical properties.
