Super Thermal Grease II
8616 Technical Data Sheet
Description
8616
The 8616
Super Thermal Grease II
is a low thermal resistance grease with a synthetic oil base that is
electrically insulating and non-corrosive. It is used to improve the thermal interface contact conductivity
between heat sinks, LEDs, motors, and heat-generating electronic components such as CPUs, GPU
chipsets, and power components. It improves the thermal interface between irregular and pitted surfaces.

Application Instructions
The conductive grease performance depends on mainly on surface preparation. Improperly prepared
contact surfaces can degrade
the paste’s
stability, conductivity, and lubrication characteristics. While the
thickness and coverage are also important, the application method itself can easily be adjusted according
to performance and application needs.
Prerequisites
•
•
•
Wear gloves and protective clothing.
Clean and dry the surface of the substrate to remove other oils and greases, as well as dust, water,
solvents, or any other contaminants.
Recommendations:
Use MG 824 Isopropyl Alcohol or MG 4351 Thinner
Equipment
•
•
•
Lint free cloth (for cleaning contact and for wiping excess residue)
Spatula or stick application tools (sized appropriately for your application)
Isopropyl alcohol or other residue-free organic solvents
To apply the grease
1. Wipe the contact with a lint-free cloth.
2. Clean the contacts with isopropyl alcohol or other non-oil based cleaner.
3. Once dry, spread grease in a thin layer onto the surface.
