• Yields a medium density, silicone foam when catalyzed
  • Two Parts mix in a convenient 1:1 ratio with a black Part A and white Part B to ensure homogeneous mixtures


  • As a flame resistant seal
  • In shock and vibration dampening situations requiring a lightweight, flexible foam with excellent thermal insulation and radiation resistance
  • Useful where stability at higher and lower temperatures is required
  • For intricate back-filling due to a low viscosity and longer work time
