Silver-Filled Conductive Silicone Grease

Silver-Filled Conductive Grease provides maximum electrical and thermal conductivity, proven lubrication properties, and protection from moisture, oxidation, and other environmental hazards. This system utilizes an advanced silicone lubricant that is compatible with metal, rubber, and plastic.

As with any compound, compatibility with the substrate should be determined on a non-critical area prior to use

Typical applications

Our Silver-Filled Conductive Grease may be used for high and low power applications including:

  • Lubrication of substation switches or circuit breakers
  • Heat dissipation from transformers
  • Low or medium speed sliding contacts
  • Static grounding on seals or o-rings
  • Extending the life of rotating switches


  • High electrical conductivity
  • Excellent thermal conductivity
  • Provides protection against wear
  • Improves electrical connections between irregular surfaces
  • Remains stable in a wide temperature range; -57 to 252 °C
  • Protects against moisture and corrosion
  • Extends the life of contacts
  • Very low viscosity vs. temperature change
  • Safe on plastics
  • Ensures electrical contact between loose or vibrating parts and small gaps

Silver-Filled Conductive Silicone Grease is in general compatible with rubber, plastic, and metal. As for any compound, prior to use the compatibility with the substrate must be determined in a non-critical area.


To avoid shock or possible fire, stop power to any system before applying conductive grease. Ensure positive and negative contacts remain isolated. Improper use can result in shorting, arcing, or shock.
