8462 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. Features and Benefits Suitable for high and low voltage applications Seals, waterproofs, insulates, and lubricates Prevents corrosion Prevents arcing and pitting Broad service temperature range of -50 to 250 C (-58 to 482 F) Temperature resistantdoes not harden, melt, bleed, dry, freeze, or separate due to temperature ufl ctuations Safe on rubbers and plastics Usage Parameters Properties Value Shelf life 5 y IS0 9001:2015 Quality Management System.
