Dow Corning 340 Thermal Compound is a grease-like silicone material with a high amount of thermally conductive metal oxide fillers.

This compound has high thermal conductivity, low oil bleed and good high temperature stability. The compound can maintain consistency up to about 177°C.

Therefore, it helps to maintain a reliable heat sink seal, which will improve the heat transfer from the electrical/electronic components to the heat sink or chassis.

Dow Corning 340 Thermal Compound is used for bases and mounting bolts of transistors, diodes and thyristor rectifiers. It can also be used for effective thermal connection of many heat sinks that require effective cooling.

Typical Use:Compound provides thermal coupling of electrical/electronic devices to heat sinks, can be applied to the base and mounting studs of transistors, diodes and silicon-controlled rectifiers.
