Frequently Asked Questions
What makes MG Chemicals 846 conductive?
The 846 grease uses carbon particles as the conductive filler. Carbon provides good electrical conductivity while remaining chemically stable and compatible with most metal contact surfaces.
Can MG Chemicals 846 be used on all types of connectors?
It is suitable for most metal connectors, switches, and ground connections. Avoid use on connectors with plastic housings that may be incompatible with the grease carrier. Always test on a small area first and verify compatibility with your specific connector materials.
How does carbon conductive grease reduce arcing?
By filling microscopic surface irregularities on contact surfaces, the grease increases the effective contact area, lowers contact resistance, and reduces the voltage gradient that causes arcing during switching operations.
Is MG Chemicals 846 suitable for potentiometers?
Yes. Carbon conductive grease is widely used for potentiometer contact treatment to reduce noise (scratchy sound) and restore smooth, consistent electrical contact on worn or oxidized wiper tracks.
What is the difference between MG Chemicals 846 (carbon) and 847 (silver) conductive grease?
The 846 uses carbon filler for general-purpose conductive applications. The 847 uses silver filler for higher conductivity requirements. Silver grease (847) has lower resistivity but is more expensive. Choose 846 for general connector and switch maintenance; choose 847 for applications requiring maximum conductivity.
