Inertol® Poxitar®
2 component, heavy duty, coal tar based epoxy coating for steel and concrete
2-component reaction hardening coating of low solvent content based on a coal tar epoxy combination with mineral fillers.
- Tough hard, heavy duty
- Abrasion and impact resistant
- Excellent resistance to water and chemicals
- Resistant to microbes
Usage
Protective coat for concrete and steel, as internal and external coating for buried and submerged structures e.g. sewage systems, chemical industries, harbour facilities etc. Also suitable where application on to damp concrete is inevitable.(The marked line should be removed)Not suitable for surfaces in contact with drinking water.
Advantages
After complete curing Inertol® Poxitar® is :- Tough hard, heavy duty
- Abrasion and impact resistant
- Excellent resistance to water and chemicals
- Resistant to microbes

Consumption
Concrete:
| Coating System | Product | Consumption |
| Primer | 1 x Inertol® Poxitar®+ 5 % Sika® Thinner DS | ~ 0.15 – 0.20 kg/m2 |
| Seal coat | 1 - 2 x Inertol® Poxitar® | ~ 0.20 - 0.30 kg/m2 per coat |
Steel:
| Coating System | Product | Consumption |
| Primer | 1 x Fraizinc® R (recommended for heavy mechanical exposure area) | ~ 0.15 – 0.20 kg/m2 |
| Seal coat | 1 - 2 x Inertol® Poxitar® | ~ 0.15 - 0.20 kg/m2 per coat |
These figures are theoretical and do not allow for any additional material due to surface porosity, surface profile, variations in level and wastage etc.
SUBSTRATE PREPARATION
For steel sand blasting or wire brushing is essential. Should be free from oil, dirt and grease. For concrete remove cement skin, loose particles etc. Cavities, pin holes should be levelled
MIXING
Inertol® Poxitar® is supplied in two parts. Stir Part B thoroughly to remix any settle part, add Component A and mix thoroughly with an electric stirrer with up and down movements for 3 minutes.
APPLICATION
Priming:
Using Friazinc® R for priming has the advantage that no under rusting occurs in case of damage to the top coat.
Application Method / Tools:
Brush application: With distemper brushes, round brushes or radiator brushes.
Roller application: With short pile lamb skin roller
CLEANING OF EQUIPMENT
Wash tools with Sika® Colma Cleaner immediately after use. Hardened material can only be removed mechanically.
