Technical Information
Product Description

EPOSSITAR 70 is a two component polyamide epoxy modified with low temperature coal tar pitch. The product produces, once cured, a tough, flexible, chemical and impact resistant film.

Advantages
  • Self-priming
  • Economical and easy to apply
  • Excellent anti corrosive ability
  • Wide range of applications
  • Low temperature curing
  • Heavy duty structural coating
  • Easily applied by roller, brush or spray
  • Exceptional resistance to impact, thermal shock and abrasion
Packaging, Coverage / Consumption

EPOSSITAR 70 is supplied as 20 Liter Kits.

Consumption: 6-6.5 m²/Liter at 100 microns.

Shelf Life & Storage

Store generally in dry covered place with a temperature between +5ºC–+35ºC and relative humidity less than 70%. In these conditions, the expected shelf life is 12 months from production date.

Application Information
Instructions for use

Mixing

The contents of the component A (resin) should be stirred thoroughly to disperse any loose settlement. The entire contents of component B (hardener) should then be added to the resin container and mixed thoroughly using a low speed electric drill (200 – 300 rpm) fitted with a suitable paddle, scrape the sides and bottom of the container and rotate the mixer throughout the missing container to ensure thorough mixing and homogeneity of the mix.

Application

After mixing, the product is ready for brush or airless spray application. 5-10% SOLVENTE 10 may be added for airless spray application. Use nozzles of 0.21”-0.0.25” and working pressure of 140-160 bar, for brush or roller add 5% volume SOLVENTE 10 only if needed.

The hardening time can vary sensitively according to environmental conditions and the type of support and, therefore the time of coating can vary sensitively according to environmental conditions and the type of support.

Cleaning

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.

Recommendations

  • EPOSSITAR 70 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%
  • The color of the coated surface will change to brown/red if cured in a high humidity environment
Surface Preparation

All surfaces must be dry, smooth, clean, sound, uncontaminated, 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.

Steel should be cleaned by sand blasting to remove all corrosion and contamination and must be immediately coated.
