Epoxy Anti-Corrosion Powder Coating for Firefighting Pipes

Surface Finish Options Overview

Product Introduction:

This product is formulated using linear phenolic epoxy resin, polyurethane-modified epoxy resin, and advanced curing agents, designed and manufactured based on the latest formulation concepts. It features high reactivity, strong adhesion, high cross-link density, and excellent resistance to chemicals, solvents, cathodic disbondment, impact, and high temperatures.

Product Usage:

For internal and external anti-corrosion coatings of water supply pipes used in firefighting systems.

Product Features:

1. Excellent adhesion to the substrate.
2. Strong anti-corrosion capability.
3. Good leveling, high gloss, and dense coating.
4. Superior high-temperature cathodic disbondment resistance.
5. Extremely strong flexibility, capable of passing the 4/5 flattening and post-grooving tests.
6. Good performance in withstanding high and low temperatures.
7. Strong resistance to boiling water.
