Controlled Volatility RTV Silicone

  • Two-part, optically clear, 1:1 (A:B) mix ratio silicone system
  • Recommended for applications where a 1:1 mix ratio and low viscosity is required.
  • For applications requiring low viscosity for superior flow and 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

Recommended Primers CF2-135 or SP-120

Note: Some bonding applications may require the use of a primer.
CF2-135 is recommended for most metallic substrates, some plastics and when cure inhibition is observed on substrate.
In general, SP-120 is recommended for use with 100% Fluorosilicones.
