Electrically Conductive Silver Grease - 7100
General Description:
For Research & Development -
Not
for drug, human, animal or food use.
7100 is a highly conductive silver filled silicone grease which is inert, thermally stable over a wide temperature range, and exhibits excellent lubricating properties when used at low to moderate loads and speeds. This material is extremely resistant to oxidation, moisture, radiation, and corrosive atmospheres. This product is also an outstanding thermal conductor, and will not corrode metallic contacts and bearings, or adversely affect any common elastomeric seals or plastic gear assemblies.

Applications:
This material is typically used on power substation switches, circuit breakers, and knife blade switches to reduce arcing and pitting on the sliding metal contacts. Previously pitted areas on old contacts which are filled with silver grease can be restored to original rated capacity with the elimination of localized heating or “hot spots”. Closed switches are prevented from sticking due to corrosion, icing, or freeze up. The grease is also effective in maintaining a continuous electrical path between contact surfaces in both power switches and ball-and-socket insulator connections, which if allowed to arc, can give rise to EMI noise. Other applications  include thermal dissipation of heat from high power electronic components such as power resistors, rectifiers, transistors, and transformers. This material is also an excellent lubricant for most non-metal to metal gear contacts where good conductivity and/or grounding is needed.
