• Yields a low to medium density silicone rubber foam when rapidly catalyzed
  • Low viscosity
  • 1:10 Mix Ratio (Part A: Part B)


  • In shock and vibration dampening situations requiring a lightweight, flexible foam
  • For intricate back-filling due to a low viscosity
  • For applications requiring low outgassing and minimal volatile condensable materials.
Meets or exceeds the ASTM E 595 low outgas specifications outlined in NASA SP-R-0022A and European Space Agency PSS-014-702, with a TML of ≤1% and CVCM of ≤0.1%
