Thermally Conductive Silicone Grease Mil-Spec High Heat Transfer System Industrial Military Grade

Thermo-Grease 04 is an opaque white heat sink grease compound, which is applied to the base and mounting studs of transistor and diodes to provide a positive heat sink seal, this facilitates heat transfer away from electrical/electronic components and into heat sinks, thereby increasing the overall efficiency and performance of the device. GR104 is grease like silicone material, heavily filled with efficient heat conductive zinc oxide and a binding agent, this combination promotes high thermal conductivity, high temperature stability, and the lowest amount of bleed and evaporation. Thermo-Grease 04 thermal compound resists changes in consistency temperatures up to 180°C; function as heat transfer media, durable dielectric insulation, barrier against environmental contaminants and as a stress-relieving shock and vibration absorbed over a wide temperature and humidity range.
