Non-Corrosive Controlled Volatility RTV Silicone

  • 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
