Overview
Two-component epoxy bitumen glass flake coating for heavy-duty protection of steel and concrete in underground/underwater service and internal linings.​

Composition
Epoxy resin, coal tar pitch, glass flakes, solvent, additives; modified amine curing agent; supplied as Part A & Part B.​

Typical uses
Underground/underwater steel structures and concrete facilities, or internal lining protection.​
Examples include gas holder/tank bottom plates and underground mines.​

Technical data (typical)

• Appearance: brown-black.​

• Theoretical consumption: 0.38 kg/m² at 150 µm DFT (loss not included).​

• Density: 1.28 kg/L.​

• Drying time (25°C): surface dry 2 h; hard dry 24 h; full cure 7 d.​

Application data (25°C)

• Mixing ratio (A:B): 25:2 or 25:3.5.​

• Induction time: 5 min.​

• Pot life: 4 h.​

• Application methods: airless spray, brush, roller.​

• Thinner: X-7 epoxy thinner, 2–8%.​

• Recoat interval: min 24 h; max 7 d.​

• Recommended DFT per coat: 50–80 µm (brush/roller 30–50 µm).​

Surface preparation
If applied over a two-component primer, surfaces must be clean, dry, and free of contaminants; abrade if beyond the maximum recoat interval.​
If used directly as the first coat, blast to Sa 2.5 or power-tool clean to St 3; surface profile 30–75 µm.​
