Bitumen Based Coating Enamel Grade C

Bitumen Based Coating Enamel is a bituminous compound reinforced with inert non-fibrous fillers for hot application. Type 2 a, b and c comply with BS 4147: 1980. It will soften gradually when heated and will change back to solid on cooling.

USAGE
Bitumen Based Coating Enamel is mainly used as anti-corrosion materials for protection of iron and steel pipes for industrial and drinking water.

• Excellent and permanent adhesion to metal


• Low water absorption


• Impact resistance


• Flexibility


• Resistance to soil stress


• Resistance to cold stress


• High electrical resistibility


• Chemically stable

  APPLICATION AND HANDLING

• Surface Preparation
       The surface of the steel pipe to be coated with Bitumen Based Coating Enamel shall
       be wire-brushed to remove all surface rust, mill scale and loose materials. Immediately
       after wire brushing the surface shall be wiped clean and dried, then apply a coat of
       Bituminous Primer and allowed to dry.



• Application
       Bitumen Based Coating Enamel shall be broken up into small pieces and heated
       slowly to the application temperature of 220°C to 250°C, and should not be heated
       to a temperature exceeding 270°C.
