Low / High Temperature,*4 ) Primed Lap Shear 200 psi (4.1 MPa), Optically Clear


  • Two-part, low viscosity clear RTV silicone
  • Designed for enhanced performance in extreme low and high temperatures
  • 10:1 Mix Ratio (Part A:Part B)


  • For applications requiring low outgassing and minimal volatile condensables under extreme operating conditions
  • As an embedding or potting compound for environmental protection of electronic assemblies and components
  • Provides protection from extremes in temperature, humidity, radiation, thermal stress and mechanical stress
  • Low viscosity for applications requiring superior flow

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%
