Potting and Encapsulating Elastomers
Thermally Conductive Silicone Potting Elastomer
Two part, Gray, 1:1 Mix ratio (A:B) Pourable and self-leveling Cures at room temperature
Enhanced thermal conductivity for removal of heat and improved reliability Low viscosity allows the potting of complex geometries without the entrapment of air Quick set-up and flexible cure schedule Applications include: potting for sensors, relays, and other electronic components requiring protection from vibration and generally harsh environmental conditions

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.
