Details
Dow 340 Heat Sink Compound is a non-curing, non-flowing, thermally conductive lubricant suitable for thermal coupling of electronic/electrical devices to heat sinks. The conductive compound is a mixture of silicone and heat-conductive metal oxides which creates a low bleed product with high thermal conductivity and high-temperature stability. Dowsil 340, and other thermally conductive materials remove heat from a heat source to the ambient, acting as a thermal bridge. Its ability to reduce heat in electronic devices makes Dowsil 340 perfect for smaller consumer electronics, which tend to generate a significant amount of heat. Compliant with MIL-DTL-47113.
