Carbon Conductive
Assembly Paste
847 Technical Data Sheet
847
Description
The 847 Carbon Conductive Assembly Paste is an electrically conductive, low-cost, non-silicone product for
applications needing stability over wide thermal ranges. The synthetic oil that is used has a low
evaporation rate that allows the paste withstand high temperatures without drying. Further, the paste
resists separation and bleeding very well, so it is unlikely to contaminate onto nearby areas.
Applications & Usages
The 847 paste improves electrical conductivity between electrical contacts and inhibits corrosion.
Features and Benefits
• High conductivity of 0.04 S/cm and low volume resistivity of 23 Ω·cm
• Doesn’t separate or bleed like silicone-based oil
• Withstands high temperature without drying, bleeding, flowing, or chemical degradation
• Lubricates even at low temperature
• Non-Corrosive
• Zero VOC

Application Instructions
The conductive paste performance depends on mainly on surface preparation. Improperly prepared
contact surfaces can degrade the pastes’ 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 847 SDS). This product is extremely messy.
• Clean and dry the surface of the substrate to remove other oils, greases, 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.
To apply the paste
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, apply the paste with the application tool to the contact, ensuring adequate coverage and
desired thickness.

ATTENTION!
DO NOT apply or smooth grease with bare finger. Carbon black is hard to clean and may transfer to other
surfaces by touch. Further, you may introduce contaminants that degrade the overall performance of the
grease.
