Low Flow


  • Two-part, thixotropic, translucent RTV silicone
  • 10:1 Mix Ratio (Part A: Part B)


  • For electronic and space applications requiring low outgassing and minimal volatile condensables to avoid condensation in sensitive devices
  • As an embedding or potting compound for environmental protection of electronic assemblies and components
  • Especially useful where moderate thixotropy is required

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%
