(FBE) Single Layer Epoxy Anti-Corrosion Powder Coating

Email:services@moutainchem.com

Specifications:

Product details

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.

Storage Period:

The product can be stored for 6 months in dry conditions below 30°C.The used coating must be re-sealed immediately to prevent moisture absorption affecting performance.Packaging: 20kg paper boxes lined with plastic bags.

Health and Safety:

The product is non-toxic and non-flammable, but follow GB15607-1995 coating operation safety regulations when using.

Precautions:

Do not mix different types of powders.Not recommended for outdoor use; fading and chalking may occur with long-term outdoor exposure.The steel pipe surface should be free of oil and moisture, with surface treatment quality reaching Sa21/2 level (GB/T8923), anchor pattern depth should be 40-100um, and the surface should be cleaned of dust and abrasives.Preheating: The temperature should be controlled between 180-230°C.
