Dielectric Silicone Grease

Dielectric Silicone Grease by Dynatex® is a silicon dioxide thickened, very high molecular weight dimethyl polysiloxane based material. It is an extremely stiff, tacky, tenacious water repellent compound, even to seawater.

Outstanding high temperature and vacuum capabilities as well make this dielectric silicone grease helps the choice for preventing corrosion on battery terminals, solar panel cable connections. Keeps moisture out of sensitive electrical connections. Many uses including spark plug wires, connectors, trailer hitch connections and other areas that may be exposed to water, condensation, or corrosion. Excellent for preventing corrosion on battery terminals and lugs. Has a wide temperature range zero-liquefy property at higher temperatures. Including summer heat. Well suited for use in wet or very humid areas. Perfect for marine applications. Used by the US Navy uses for outdoor antenna connectors. Silicone, not petroleum based. Will not flow or “drip” at high temperatures. Safe on nearly all plastics and rubber including Viton O-Rings.
