3-Layer Polyethylene (FPE) Anti-Corrosion Epoxy Powder Coating

Surface Finish Options Overview

mankhwala 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.

Kugwiritsa Ntchito Zogulitsa:
Suitable for anti-corrosion coatings on various oil and gas pipelines.

Zambiri Zamalonda:

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.
