This product is formulated using phenolic epoxy resin and incorporates modified conductive polymers and conductive materials, combining the advantages of intrinsic and doped conductivity. It is specifically designed for conductive heavy-duty anti-corrosion powder coatings. The surface resistivity of the coating can reach below 10⁵ Ω, effectively eliminating static electricity accumulation in gas drainage pipes and preventing static sparks, thereby enhancing safety. The coating 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.
Special anti-static and anti-corrosion coating for gas ventilation and drainage pipes in coal mines.
