2K epoxy coating system covering primer and topcoat for petroleum product tank interiors including aviation fuel, diesel and lubricant oil service. Non-toxic, abrasion-resistant film. Sa2.5 prep, 150–200µm total DFT system.
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.
Packing: primer Part A 20 kg, Part B 2.5 kg; topcoat Part A 20 kg, Part B 3 kg.
Storage: dry, cool, ventilated; away from fire; avoid strong sunlight; no outdoor storage.
Shelf life: 12 months.
