low viscosity elastomers advancedengineering electronics/optoelectronics




Low Outgassing clear coating, cure can be heat accelerated.


  • Two-part, optically clear, 1:1 (A:B) mix ratio silicone system
  • RoHS/REACh compliant
  • Recommended for applications where a 1:1 mix ratio and low viscosity is required.


  • For applications requiring low outgassing and minimal volatile condensables to avoid condensation in sensitive devices
  • As an embedding or potting compound for electronic assemblies and components to provides protection from extremes in, humidity, radiation, thermal stress and mechanical stress
  • Suitable as an adhesive in low-strength applications such as solar cell arrays where clarity and low volatility are important

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%
