Super Thermal Grease III
8617 Technical Data Sheet
Description
8617
The 8617
Super Thermal Grease III
is a low thermal resistance, non-corrosive grease. It uses an
extremely thermal stable synthetic oil that is electrically insulating. It is used to improve the thermal
interface contact conductivity between heat sinks, LEDs, motors, and heat-generating electronic
components such as CPUs, GPUs, and power components. This grease 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.
