DOWSIL 340 also known as Dow Corning 340 is silicone based thermally conductive compound providing thermal coupling of electrical and electronic devices to heat sinks.
Applications: Compound is applied to the base and mounting studs of transistors, diodes and
silicon-controlled rectifiers. It can also serve as an effective thermal coupler for many heat sink
devices where efficient cooling is required. It is also suitable for aircraft engines where heat sink
properties are required.
Features: High thermal conductivity; Low bleed; Stable at high temperatures.
Composition: Grease-like silicone fluid thickened with metal oxide filler.
Temperature Range: Resists changes in consistency at temperatures up to +177°C
