Surface Finish Options Overview

Product Introduction:

This product is carefully formulated using epoxy resin and functional curing agents. It features high reactivity, strong adhesion, high cross-link density, and excellent resistance to chemicals, solvents, cathodic disbondment, as well as superior flexibility and impact resistance.

Product Usage:

Suitable for anti-corrosion of oil and gas transmission pipelines, municipal water supply, drainage, sewage, circulating water, chemical industry, and can also serve as a base layer for anti-corrosion in thermal insulation and submarine cable applications.

Product Features:

Excellent adhesion to the substrate.
Good leveling of the coating surface with moderate gloss.
Strong resistance to permeation and corrosion.
High surface hardness and dense coating, good resistance to plant root penetration.
Excellent high-temperature cathodic disbondment resistance.
Low melting temperature, high reactivity, high curing completion rate.
