Dow Corning340 thermal compound is a grease-like silicone material filled with a high volume of thermally conductive metal oxide filler. This compound features high thermal conductivity, low oil bleed, and excellent high-temperature stability. The compound maintains its consistency up to approximately 177°C. As a result, it helps maintain reliable heat sink sealing, which improves heat transfer from electrical/electronic components to the heat sink or chassis.

Dow Corning 340 thermal compound is used for the base and mounting bolts of transistors, diodes, and silicon-controlled rectifiers. It can also be used for effective thermal connections in many heat dissipation devices requiring efficient cooling. Additionally, it serves as a high-voltage anti-corona, non-flammable coating for connections in high-voltage flyback transformers used in televisions and similar applications.

Dow Corning 340 is a thermal compound lubricant, consisting of a grease-like silicone material filled with a high volume of thermally conductive metal oxide filler. This compound offers thermal conductivity, low oil bleed, and good high-temperature stability. The compound maintains its consistency up to approximately 177°C. Therefore, it helps ensure reliable heat sink sealing, which enhances heat transfer from electrical/electronic components to the heat sink or chassis.
