Silicone Heat Sink Grease

 Silicone heat sink grease #SS 7107  is a non-curing, water resistant paste heavily filled with heat conductive metallic oxides in a Silicone base.  It is used for maintaining a positive heat-sink seal that improves heat transfer from the electrical / electronic component / device to the heat sink or chassis, there by increasing the overall efficiency of the component / device.

Product features:

·               Capable of high thermal conductivity

·               Bleed resistant, non-drying, non-melt and non-curing in nature.

·               Heat – resistant up 200⁰ C.
