8462 Silicone Grease is a translucent, hydrophobic, silicone dielectric compound that offers premium water repellency and corrosion protection. The main purpose of dielectric grease is to seal, waterproof, lubricate, and insulate both indoor and outdoor electrical connections with a layer of non-hardening dielectric paste. 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.

Silicone dielectric grease 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. This silicone-based grease is useful in marine environments and harsh weather conditions
