PLH54-2 Refined Oil Tank Internal Lining Coating

Overview
Two-component epoxy tank internal lining coating (primer/topcoat) for refined oil storage compartments and tanks.​

Composition
Epoxy resin, corrosion-resistant pigments and fillers, blended solvent, additives, modified amine curing agent; supplied as Part A & Part B.​

Typical uses
Internal lining anti-corrosion for compartments and storage tanks for gasoline, diesel, kerosene, and engine oil.​
For steel storage tanks holding multiple products where static accumulation may occur.​

Technical data (typical)

• Appearance: primer iron red or grey; topcoat grey.​

• Theoretical consumption: 0.24 kg/m² at 100 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): primer 20:2.5; topcoat 20:3.​

• Induction time: 5 min.​

• Pot life: 2 h.​

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

• Thinner: X-7 epoxy thinner, 3–9%.​

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

• Recommended DFT per coat: 70–100 µm (brush/roller 30–50 µm).​

• System: PLH54-2 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

• System compatibility: PLH54-2 refined oil tank internal lining primer + topcoat.​
