Key Benefits of Epoxy Coal Tar

Superior Chemical Resistance

Resists sea water, tap water, de-ionized water, hydrochloric and sulfuric acid fumes, and dilute acids.

Temperature Resilience

Performs reliably at temperatures up to 70–80°C, suitable for demanding industrial conditions.

Non-Porous Finish

Prevents moisture and chemical penetration, ensuring long-lasting protection.

High Adhesion

Bonds effectively to properly prepared concrete and mild steel surfaces.

Fast Curing

Achieves initial set in 3–5 hours and full curing in 3–5 days at 30°C.

Preparation and Application

Surface Preparation

Concrete Surfaces

  • Ensure the concrete is fully cured (minimum 28 days), stable, and free from cracks, potholes, or honeycombs.
  • Remove dirt, grease, curing compounds, and other contaminants via mechanical abrasion or acid etching.
  • Ensure the surface is dry, clean, slightly rough, and properly sloped.

Mild Steel Surfaces

  • Sandblast to remove rust and scale for optimal adhesion.
  • If sandblasting is not feasible, use power tool cleaning, wire brushing, or coarse emery paper.
Coating Preparation
  • Mixing Ratio: 1 part Epoxy Resin to 2 parts Epoxy Coal Tar (by weight), i.e., 100 pbw Epoxy Resin to 200 pbw Epoxy Coal Tar.
  • Process: Thoroughly mix the Epoxy Resin and Epoxy Coal Tar in a clean container until uniform. Prepare small batches to maintain workability.
  • Tip: Mix only what can be applied within 20 minutes to avoid premature setting.
Application

General Application

  • Apply at least two coats using a brush or roller on clean, dry surfaces to achieve a film thickness of 125–150 microns per coat.
  • Allow 3–5 hours drying time between coats at 30°C.

Membrane for A.R. Brick Lining:

  • Clean the surface with a wire brush to remove dust and moisture.
  • Apply one coat of Epoxy Coal Tar and sprinkle quartz sand over the wet coating to enhance adhesion for brick/tile lining.

Tank Application

  • Apply one coat of Epoxy Coal Tar Primer.
  • Over the primed surface, apply a 2–3 mm Epoxy Screed lining.
  • Finish with a topcoat of Epoxy Coal Tar.

Curing

  • Initial Set: 3–5 hours at 30°C.
  • Final Set: 24–48 hours at 30°C.
  • Full Curing: 3–5 days at 30°C.
  • Note: Prevent water or chemical exposure during curing to ensure optimal performance.
Storage and Shelf Life
  • Epoxy Resin : 25 or 30 kg in plastic carboys or MS drums.
  • Epoxy Coal Tar : 30 kg in plastic carboys or MS drums.
  • Custom Packaging : Available for export per customer requirements.
Safety Precautions
  • Personal Protection : Wear protective gloves, goggles, and a mask during mixing and application.
  • Cleaning : Clean equipment and hands with soap and water before the coating sets.
  • Flammability : Store away from ignition sources and handle with care to avoid spills.
