In contrast to the actual electric contacts, some mechanisms such as insulators and connectors require the use of dielectric lubricants in order to isolate the cables and connections.

These applications require high temperature lubricants resistant to humidity or that have good sealing properties.
These lubricants should be compatible when in contact not only with metals but also with all commonly used plastics and elastomeric seals commonly used excepted silicone based seals.

IKV-TRIBOSTAR SSI 1302 - Insulation pastes

Lubricant pastes suitable for the use with seals, plastic parts for valves and fittings, sealing of glass apparatus, and agro-food industry applications. They are also used as dielectric pastes for the protection of electric insulators against humidity.
