Technical Data Sheet
Super Thermal Grease II
Description
8616 is a paste with high thermal conductivity. It is designed to reduce thermal resistance between irregular
metal surfaces. It is most commonly used to improve heat flow between heat sinks, LEDs, motors, and
heat-generating electronic components such as CPUs, GPUs, and power components.

safety guidelines, and regulatory compliance.
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.
