Mastertop™ is engineered to supply a superior insulating and exothermic blanket covering the molten metal, thus preventing heat loss and inconsistent solidification. With alloy specific formulations, designed for maximum protection from undesirable atmospheric chilling, Mastertop™ assures the proper formation of piping by allowing the complete feeding of the casting.

  • Prevent costly shrink defects
  • Promotes effective piping of risers through reproducible burn quality
  • Easy to remove "puck"
  • Steady burn rate
  • Low smoke and no odor
