Introduction
Epoxy Anti-Corrosion Powder Coating for Firefighting Pipes is formulated with linear phenolic epoxy resin, polyurethane-modified epoxy resin, and advanced curing agents. Designed for protective coating applications on firefighting water supply pipes, it offers high reactivity, strong adhesion, high cross-link density, and resistance to chemicals, solvents, cathodic disbondment, impact, and elevated temperatures.
Features
Strong Adhesion
Provides strong adhesion to the prepared substrate.
Corrosion Protection
Designed to protect steel pipe surfaces against corrosion.
Smooth Finish
Offers good leveling, high gloss, and a dense coating.
Cathodic Disbondment Resistance
Provides resistance to cathodic disbondment at elevated temperatures.
Flexibility
Designed to withstand flattening and post-grooving tests as specified.
Temperature Resistance
Offers performance under both high- and low-temperature conditions.
Boiling Water Resistance
Provides resistance to boiling water exposure.
Application
Suitable for internal and external anti-corrosion coatings on steel water supply pipes used in firefighting systems.
