3M thermally conductive grease TCG-2035 is an ultra high performance thermal interface material for transferring thermal energy from a heat source (e.g.: processor chip, graphics chip, etc.) to a heat sinking or heat spreading surface. The 3M thermally conductive greases are high performance thermal interface materials for transferring thermal energy from a heat source (e.g. Processor chip, graphics chip, high power LED) to a heat sink. The proprietary blend of inorganic fillers contained in an organic matrix (non silicone) ensures high thermal conductivity and low thermal resistance. Grease products are available in 2 versions - standard viscosity and a lower viscosity version that can be useful in screen printing application methods.
