Premium Carbon Conductive Grease
8481 Technical Data Sheet
8481
Description
The 8481 Premium Carbon Conductive Grease is an electrically conductive grease with a synthetic oil
base. This product is similar to the MG 846 silicone conductive grease, but unlike its silicone counterpart
the 8481 synthetic-oil grease is essentially non-bleeding. Further, it includes corrosion inhibitors that
provide superior corrosion resistance.
Applications & Usages
The 8481 grease lubricates and improves electrical connections between sliding surfaces and parts,
ensuring good grounding connection. It is also used to improve electrical continuity between irregular and
pitted surfaces, as well as providing an economical way to protect switches against corrosion.
Features and Benefits

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 (see 8481 SDS). This product is messy.
Clean and dry the surface of the substrate to remove other oils and greases, as well as dust, water,
solvents, or any other contaminants.
Recommendation: Use MG 824 Isopropyl Alcohol
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
NOTE: Avoid oil-based cleaners (like WD-40) that are designed to leave a film on the metal surface.
Contaminant oil or grease films may act like barriers reducing the electrical contact between the
conductive paste and the metallic substrate.
