Technical Data Sheet
Silicone Grease
Description
8462 is a dielectric silicone grease. It seals, waterproofs, lubricates and insulates indoor and outdoor
electrical connections with a layer of non-hardening silicone compound. It is electrically insulating but
allows current to flow through metal contacts, providing environmental protection without inhibiting
connectivity or causing short circuits. It is also good for lubricating and sealing rubber and plastic parts.
It is commonly used on outdoor lighting, scoreboards, traffic lights, high voltage poles, transformers,
disconnects, switching mechanisms, electrical contacts, spark plugs, battery terminals, fasteners, seals,
gaskets, plastic insulators, and O-rings. It is useful in marine environments and harsh weather conditions.

Storage
Store between 0 and 10 °C [32 and 50 °F] in dry area to minimize settling. You many also store this
product at higher temperatures but this can cause settling. If settling occurs, mix thoroughly until the
product is homogeneous again.
Health, Safety, and Environmental Awareness
Please see the 8462 Safety Data Sheet (SDS) for further details on transportation, storage, handling,
safety guidelines, and regulatory compliance.
Application Instructions
