(An Exothermic cum Insulating Anti-Piping Compound for covering risers of all types of Iron and Steel).
POWEREX 700 powder reacts exothermically after contact with the liquid metal in the feeder. During the exothermic reaction, the volume of the powder grows by 50 % to 100 % and creates a highly insulating powder residue. This double effect of heating and insulating the feeder head surface with POWEREX 700 anti-piping compounds, permits the longest possible action of the atmospheric pressure on the liquid feeder metal. This leads to an optimum yield of the feeder and to the prevention of secondary shrinkage cavities.
POWEREX 700 powder must be kept dry.
