PLH54-3 Crude Oil Tank Internal Anti-Static Coating

Overview
Two-component epoxy anti-static coating system (primer/topcoat) for crude oil tank internal linings and crude oil cargo tanks.​

Composition
Epoxy resin, reinforced resin, corrosion-resistant pigments and fillers, conductive fillers, additives, modified amine curing agent.​

Typical uses
Dedicated for internal protection of crude oil storage tanks and ship crude oil cargo tanks in areas with static accumulation risk.​

Technical data (typical)

• Appearance: primer grey; topcoat light grey.​

• Theoretical consumption: 0.29 kg/m² at 120 µm DFT (loss not included).​

• Density: 1.4 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): 20:2.​

• Induction time: 5 min.​

• Pot life: 3 h.​

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

• Thinner: X-7 epoxy thinner, 3–9% (more for air spray/roller).​

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

• Recommended DFT per coat: 80–120 µm (brush/roller 40–50 µm).​

• System: PLH54-3 anti-static primer + topcoat.​

Surface preparation
After compartment/tank assembly, abrasive blast clean to Sa 2.5; surface profile 30–75 µm.​
If an inorganic zinc silicate shop primer is used for temporary protection, check curing; if under-cured, re-blast to remove it and clean contaminants before coating.​

System compatibility / packing / storage
