Ultra Low Outgassing™ Potting and Encapsulating Silicone Elastomer

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