• Two-part, red, low specific gravity, RTV silicone
  • 1:1 Mix Ratio (Part A: Part B)


  • For applications requiring low outgassing and minimal volatile condensables under extreme operating conditions to avoid condensation in sensitive devices
  • Use a bonding, sealing, or potting material in electronic and space applications
  • Provides radiation resistance, low thermal conductivity, oxidation stability, thermal stability and good ablative characteristics
  • Especially useful to bond solar cells to solar array panels
  • 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%
