Technical Information
Product Description

EPOSSITAR 100 CR is a two component solvent free epoxy polyamine coating, modified with low temperature tar. It is specially formulated for high build applications. Once cured, it produces a tough, flexible, chemical and impact resistant film. EPOSSITAR 100 CR is formulated to be easily applied, as thick as 200 microns in one coat. It provides excellent resistance to aggressive chemicals, water, acids, and alkalis.

  • Self-priming
  • Excellent anticorrosive ability
  • 100% solid content
  • High build
  • Low temperature curing
  • Heavy duty structural coating
  • Easily applied by roller, brush or spray
  • Exceptional resistance to impact, thermal shock & abrasion

Application Information
Instructions for use


Prior to application, stir component A (resin), then add component B (hardener) to it and mix thoroughly with a low speed electric drill (200 – 300 rpm) fitted with a suitable paddle to obtain a homogenous mixture.


After mixing the two components, product will be ready for brush or airless spray application 5-10% SOLVENTE 10 may be added for airless spray application. Use nozzles of 0.21” – 0.025”, and working pressure 140 –160 bar. For brush or roller add 5% volume of SOLVENTE 10 if needed.

EPOSSITAR 100 CR is generally applied as a two coats application with a wet thickness of 200-300 micron per coat.

The hardening time vary sensitively according to environmental conditions and the type of support.


Tools and equipment should be cleaned with SOLVENTE 10 immediately after use. Hardened material should be removed mechanically. Spillages should be absorbed with sand or sawdust and disposed of in accordance with local regulations.


  • EPOSSITAR 100 CR should not be applied over existing coatings
  • For application in hot weather, it is strongly recommend to shade the working area and to keep the equipment used cool
  • Application should not be undertaken if the temperature is below +5ºC, nor when the prevailing relative humidity exceeds 90%
Surface Preparation

All surfaces must be dry, smooth, clean, and free from dust or loose material. Concrete surfaces must be fully cured and laitance must be removed by any suitable method.

For old concrete, all contamination must be removed and a sound clean substrate should be exposed. Mechanical means of preparation are preferred followed by the removal of dust and other loose debris using an industrial vacuum.

Cracks should be reinforced with fibre mesh and must then be treated with epoxy mortar. Contact Colmef Technical Department for recommended products.
