Epoxy Coal Tar

Epoxy Coal tar is known that solvent free Epoxy Coating. It is non porous have good chemical resistant.

Resistance To

  • Sea Water, Tap water de-ionized water
  • Hydrochloric & Sulphuric Fumes
  • Dilute Acid

Resistant to temperature :

  • 70°C to 80°C

Application of Epoxy Coal Tar Coating:

  • As a membrane coating for A.R. Brick/Tile lining
  • Protective coating of pipe line
  • Protection of Steel & concrete structure & chemical factories
  • Under side of motor vehicle chasis.

Preparation of Coating :

  • Epoxy coal tar consisting of Epoxy Resin & Coal tar. In order to obtain good working consistence the average mixing ratio as under:
  • Epoxy Resin : 100 pbw
  • Epoxy Coal Tar : 200 pbw

The ratio will be slightly depending upon the temperature and working condition.


Surface Preparation

A) Concrete Surface:

The concrete/cement plastered surface shall be stable in construction free from cracks, pot holes, honey combs etc. The concrete should be cured as per for minimum of 28 days moisture free and the surface shall be dry, clean even in slightly rough, in line and level, maintaining required slope etc.,

The Surface must be clean & sound, remove all dirt, grease, curing compounds and other foreign matter by mechanical abrasion for acid etching. Remove water & dust from all surface prior to application.

B) Mild Steel Surface:

Mild steel surface are best prepared by sand blasting to remove all rust or scale. If sand blasting is not possible, power tool cleaning, wore brushing or abrading with coarse emery paper may be resorted to.

Application:

  • After proper mixing Epoxy Coal tar should be applied on clean & dry surface by wire brush.
  • Epoxy coal tar is a self hardening due to chemical reaction which occurs when the Epoxy
  • Resin & Epoxy Coal tar are mixed together.
  • An initial setting in 3 to 5 hours at 300C
  • Final setting occur in 24 to 48 hours at 300C
  • Curing time 3-5 days at 300C

Mechanical & Physical Property:

01 Working time 30°C 20 minute
02 Mixing Viscosity @ 25°C 3000 to 6000 m pa.
03 Specific gravity 1.15 ± 0.05
04 Covering Capacity 300-350 grm/per coat/M2
05 Thickness 100 micron / coat

It is advisable to apply at least two coats to get an adequate film thickness.

Equipment Cleaning:

  • Equipment & Hand should be cleaned before Epoxy Coal tar begins to set, soap and water is to be used for cleaning the purpose.

Safety

  • At the time of mixing or applying Epoxy Coal tar wear protection hand gloves, goggles and mask for protection.

Storage life:

01 Epoxy Resin 12 month at the temperature 30°C (±2°C)
02 Epoxy Coal tar 12 month at the temperature 30°C (±2°C)

All two components are stored in cool and dry place under the roof until ready to use it original unopened (Sealed) containers.

Packing:

01 Epoxy Resin 25 OR 30 kgs. Plastic Carboy OR MS Drum
02 Epoxy Coal tar 30 kgs. Plastic Carboy OR MS Drum
