  • One-Part, translucent silicone RTV
  • Non-slumping in thin sections


  • For applications requiring extreme low temperature, low outgassing and minimal volatile condensables under extreme operating conditions
  • As a sealing, caulking, adhesive or potting material in electronics and space applications requiring minimal outgassing to avoid condensation in sensitive devices
  • For bonding and sealing in applications such as overhead or vertical joints that require a non-slumping and one-part material
  • For applications requiring a broader operating temperature range

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%
