• Two-part, translucent silicone system
  • Offers a high tear strength, good physical properties and a broad operating temperature range
  • Convenient 1:1 mix ratio (Part A:Part B)


  • For electronic and space applications requiring Ultra Low OutgassingTM and minimal volatile condensables under extreme operating conditions
  • To provide protection of electronic components and assemblies against shock, vibration, moisture, dust, chemicals and other environmental hazards
  • Ideal for use in potting connectors, cable harness breakouts, molded high-voltage terminals, seals and gaskets due to its high tear strength
  • For applications requiring a broader operating temperature range
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 ≤0.1% and CVCM of ≤0.010%
