Nurprime SB
Solvent Based Bitumen Coat
Nurprime is solvent based black bitumen paint. When dry the product forms an odorless and taints free bitumen film suitable for the protection of metals, concrete roofing, felt, fiber cement, corrugated iron, asphalt and wood against water attack.
Uses of Nurprime SB
Nurprime provides an effective water proof, weather proof, corrosion resistant protective coatings. It is resistant to low concentrations of alkalis and acids and withstands prolonged oxidation it is suitable for application to a wide variety of materials including iron and steel, lead, zinc aluminum, asbestos-cement, concrete, stone, wood, felt and brick and is mainly used for metal protection, protecting drinking water tanks as a protective coating for concrete structures, stone, bricks, concrete screeds and sand/cement surfaces over coating felt/woo.

Application
Nurprime is ready for use and should not be thinned. Apply by brush or spray, A minimum of two coats of bitumen paint should be applied, the first should be allowed dry (Normally 2- 4 hours depending on weather condition) before the second is applied application rate 4-6m2 /Liter however the coverage will depend on the porosity of the Substrate. Drying time is 3-4 hours at normal atmospheric temperature. Keep away from sources of ignition. Can be stored atmospheric temperature.
Features
Cleaning
can be removed from equipment and tools with any suitable solvents such as kerosene or Gasoline or Diesel.
Coverage
Approximate rate: 0.2 – 0.3 kg/m2. The exact rate will depend upon the porosity or smoothness of the surface.
Storage
Up to 6 months in tightly sealed, undamaged container. It should be stored indoors under conditions applying to products with flash point of 38 degree Celsius.
Health & Safety
Flashpoint for the product is 38 degree Celsius, so it’s a flammable material, in case of fire use dry powder, Carbon Dioxide (CO2) foam. Do not smoke. Wipe off spillages immediately.
Skin Coat
The solvent may have a narcotic effect if inhaled or absorbed through the skin. Wear protective clothing and goggles storage.
