Fosroc Nitocote EN901

Fosroc Nitocote EN901 is a high build, two-pack epoxy-novolac system specially designed to provide a tough and impermeable high chemical resistant film in aggressive chemical conditions.

Best Uses

Nitocote EN901 is an epoxy novolac coating designed to provide protection to concrete and steel structures in aggressive chemical conditions. The material is particularly suitable in wastewater treatment, desalination, food processing, electric power, chemical manufacturing, fertiliser and insecticide plants, petroleum refineries and pulp and paper mills.

Fosroc Nitocote EN901 may be used with or without Nitoflor FC Antislip grains as a heavy-duty floor coating in applications such as chemical processing and drum storage areas, loading docks and ramps. It may also be used in conjunction with glass fibre cloth to increase the thickness of the system or to reinforce structures subjected to aggressive chemicals.

• 100% solids, solvent free
• Exhibits excellent chemical resistance in pH levels ranging from 1-14 at 25°C
• Excellent adhesion to properly prepared concrete, mild steel, and other substrates
• Excellent abrasion resistance

Nitocote EN901 is a solvent free, highly crosslinked, high build epoxy novolac based coating. Nitocote EN901 is a two-part grey material applied by brush or roller. It is formulated to be applied in two coats to achieve a minimum total-dry-film thickness of 400 microns. Higher thickness can be specified.

Application

Preparation of concrete surfaces
All surfaces, which are to receive the coating, must be at least 28 days old or have a moisture content of less than 5%. These surfaces shall be dry, sound and free from debris and loose material. The substrate must be free from contamination such as oil, grease, wax, dirt or any other form of foreign matter which might affect adhesion. All surfaces should be grit blasted to remove all foreign matter and open up all blowholes and provide a suitable key for Nitocote EN901. All blow holes and imperfections should be filled with Nitomortar FC.

Preparation of steel surfaces
All surfaces should be grit blasted to meet the requirements of BS7079 SA 2.5. The coating work should be programmed so that newly cleaned steel is coated as soon as possible before the formation of rust or scale.

Priming
Nitocote EN901 is designed to be used without primer. However, if the concrete substrate is considered porous, Nitoprime 25 can be used.

Once mixed, Nitocote EN901 should be immediately applied to the prepared surface, ensuring a continuous coating of uniform thickness is obtained. A maximum film thickness of 200 microns can be achieved on vertical surfaces per coat. A stiff nylon brush or short nap roller is recommended for such application.
