MG Chemicals Silver Conductive Grease 8463A - High Thermal

In this review the MG Chemicals 8463A silver conductive grease is evaluated for technicians and engineers who need a conductive lubricant that also helps manage heat. The product stands out because it pairs a silicone-based oil with silver-coated aluminum flake to improve electrical contact between irregular surfaces while offering a claimed thermal conductivity benefit. This review focuses on real-world uses such as grounding, slip rings, rotary switches and potentiometers, and assesses whether the 8463A delivers reliable conductivity, corrosion inhibition, and ease of application from its 5.5 g dispenser.

Key Features

• Improves electrical connections: The paste fills voids between adjoining parts to ensure a continuous electrical path across irregular surfaces.
• Low resistivity: With resistivity under 0.2 ohm-cm, it provides notably better conduction than many carbon-based greases.
• Thermal transfer: The formula offers thermal conductivity of 1.0 W/(mK), helping dissipate heat at contact points.
• Silicone-based carrier: The silicone oil base maintains lubricating properties while remaining compatible with many contact types.
• Corrosion inhibition: The grease helps protect metal surfaces from oxidation and environmental degradation.
• Compact dispenser: The 5.5 g dispenser lets users apply the correct amount to small or precision components without waste.

Who It's For

The 8463A is aimed at electronics technicians, maintenance staff, and hobbyists working with rotating electrical contacts, slide connectors, slip rings, and variable capacitors who need a conductive lubricant that also helps with heat transfer. It is particularly useful where a low-resistance path and environmental protection are both required.

It is not intended as a bulk service solution for large mechanical bearings or as a replacement for specialized high-temperature greases outside the product's thermal range; users needing large-volume lubrication should look for industrial-sized dispensers or greases formulated specifically for heavy mechanical loads.

Pros & Cons

Pros

• Improves electrical contact on irregular surfaces and maintains continuity where metal-to-metal fit is imperfect.
• Lower resistivity than carbon-based greases, delivering better conductivity for sensitive contacts.
• Provides thermal conductivity that helps dissipate heat at contact points.
• Silicone carrier and corrosion inhibition increase component longevity in exposed environments.

Cons

• Small 5.5 g dispenser is convenient for precision work but may be insufficient for larger maintenance tasks.
• As a silver-coated aluminum compound it is formulated for electrical contacts, not for heavy mechanical load bearing applications.
