Technical Data Sheet
Silicone Heat Transfer Compound
Description
860 is a thermally conductive silicone paste. It is designed to reduce thermal resistance between irregular
metal surfaces. It is most commonly used to improve heat flow between heat sinks and heat-generating
components, such as CPUs, GPUs, LEDs, motors, and power components.

Application Instructions
To apply the grease:
1.
Wear protective gloves.
2.
Clean and dry the surface being lubricated with a lint-free cloth or brush and a zero-residue cleaning
solvent, such as MG 824 Isopropyl Alcohol.
3.
Apply a thin, even layer of grease using a spatula or other appropriate application tool.
