(Formerly known as Nitocote EP901)
High chemical resistant protective lining
Nitocote EN901 is an Epoxy Novolac lining designed to provide Solid content
protection to concrete and steel structures in aggressive chemical conditions. The material is particularly suitable in wastewater treatment plants, desalination plants, food Specific gravity
processing plants, pump and paper mills, electric power plants, chemical manufacturing plants, fertiliser and insecticide plants and petroleum refineries.
Tack-free time
Nitocote EN901 may be used with or without Fosroc Anti-slip grains as a heavy-duty floor coating in applications such as Overcoating time
chemical processing and drum storage areas, loading docks and ramps. It may also be used in conjunction with glass Full cure
fibre cloth to increase the thickness of the system or to reinforce structures subjected to aggressive chemicals.

The fully cured coating is resistant to the splash/spillage of Nitocote EN901 is a solvent free, highly crosslinked, high build epoxy-novolac-based coating. Nitocote EN901 is a two- part material and can be applied by brush, roller or airless spray. Nitocote EN901 is grey in colour. It is formulated to be applied in one or two coats to achieve a minimum total-dry- Bleach (Sodium hypochlorite) KeroseneBoric Acid * film thickness of 500 microns.

The cloth should be laid directly on the first coat whilst wet and should be pressed in and smoothed out with a split washer roller.

It is recommended that Nitocote EN901 should be removed from tools and equipment mechanical mixing be employed using a Jiffy mixer on a slow with Nitoflor Sol* immediately after use.

Once mixed, Nitocote EN901 should be immediately applied Substrate, ambient and product temperature must remain to the prepared surface ensuring a continuous coating of above 15°C during application and curing. Minimum material/container temperature for spray application is 20°C. Avoid moisture contamination.
Stiff nylon brush or short nap roller is recommended for such application. Faster rate of application is possible using airless Nitoflor EN901should not be applied on to surfaces known to, or likely to suffer from, rising dampness, potential osmosis problems or have a relative humidity greater than 75% as measured in accordance with BS 8203 Appendix Application should not be undertaken if the temperature is Air conditioned storage at high ambient temperatures is below 5°C, or is 5°C and falling, nor when the prevailing Nitocote EN901 may not be colour stable when in contact with some chemicals or direct sunlight.
