Epoxy Anti-Corrosion Powder Coating for Firefighting Steel 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 a new formulation concept. It features high reactivity, strong adhesion, high cross-link density, and excellent resistance to chemicals, solvents, cathodic disbondment, as well as superior flexibility, impact resistance, and high-temperature resistance.

Product Features:

Excellent adhesion to the substrate.

Strong anti-corrosion capability.

Good leveling, high gloss, and dense coating.

Superior high-temperature cathodic disbondment resistance.

Extremely strong flexibility, capable of passing the 4/5 flattening and post-grooving tests.

Good performance in withstanding high and low temperatures.

Strong resistance to boiling water.

Powder Coating Performance Parameters

Cured Powder Coating Performance Parameters

Compliance Standards:

GB/T 5135.20-2010; CJ/T 120-2008

Application Fields:

Anti-corrosion coating for internal and external surfaces of water supply pipes used in firefighting.

Application Processes:

Spraying, dip coating, etc.

Precautions:

The steel pipe surface should be free of oil and moisture; the surface treatment quality should reach Sa2 1/2 level (GB/T 8923); the anchor pattern depth should be 50-90 mm; dust and abrasives on the steel pipe surface should be blown clean. Preheating temperature should be controlled between 180-240°C.

The product should be stored in a well-ventilated, dry indoor environment with a temperature below 30°C, away from heat sources, corrosive chemicals, and chemical solvents, and protected from strong light exposure. The stacking height should not exceed four layers. Avoid long-term pressure and ensure the packaging box is sealed to prevent caking and moisture, which can affect fluidization performance.

To ensure thorough curing of the epoxy coating and better anti-corrosion performance, it is recommended to preheat the steel pipe surface to above 200°C to improve the curing completion rate.
