Coal-mine epoxy anti-static and anti-corrosion powder coating is a heavy-duty conductive coating built on phenolic epoxy resin with modified conductive polymers and conductive materials. It combines intrinsic and doped conductivity, reaching a surface resistivity below 10⁵ Ω so that static charge cannot build up on gas drainage pipes — eliminating spark risk in a gas-rich mine atmosphere. The film is highly reactive, strongly adherent and highly cross-linked, with good chemical, solvent and cathodic-disbondment resistance, plus flexibility and impact strength.

Product Features

• Excellent adhesion to the substrate.
• First-grade material combining intrinsic and doped conductivity.
• Surface resistivity reaches 10⁵ Ω, effectively eliminating surface charge accumulation.
• Superior high-temperature cathodic disbondment resistance.
• Low melting temperature, high reactivity, high cure completion, good mechanicals.
• Contains composite flame retardants for a degree of flame resistance.

Application & Curing

Handling & Precautions

• Surface preparation: oil-free, water-free; blast to Sa 2½ (GB/T 8923), anchor depth 40–100 µm; blow off dust and abrasives.
• Preheating: 180–250°C, never above 250°C; preheat steel pipe surface above 200°C for cure completion.
• Storage: ventilated, dry, below 30°C, away from heat, corrosives and solvents, out of strong light; stack ≤ 5 layers, keep sealed to prevent caking.
• Outdoor use: not recommended — may fade and chalk under UV.
• Safety: non-toxic, non-flammable; follow GB 15607-1995 coating-operation safety rules.
