Soft, very low modulus coating


  • One-part, flowable, solvent free silicone


  • For industrial or space applications requiring low outgassing and minimal volatile condensables under extreme operating conditions
  • As a conformal coating on rigid and flexible circuit boards
  • For encapsulating sensitive electronic components such as connectors and switches
  • To provide protection against harsh environments while maintaining good dielectric properties
  • For applications requiring a broader operating temperature range

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%
