Epoxy coal tar is composed of two main components, an epoxy (A) and a hardener (B) two-component paint, featuring excellent adhesion, toughness, resistance to moisture, water, and chemical media. It possesses the ability to prevent various ions from passing through the paint film and has the characteristic of expanding and contracting with the coated object. The paint film never peels off or cracks. Thickness: 0.5-1.0mm. Epoxy coal tar is a cost-effective anti-corrosion method, with a smooth, dense, and hard coating, strong bonding power, and excellent resistance to salt, alkali, seawater, soil microbial corrosion, and plant root penetration. When used in combination with glass fiber cloth, it enhances the mechanical properties of the anti-corrosion layer. Widely used for the external anti-corrosion of water supply and heating pipelines.
