Dielectric grease is a unique product that is used to protect terminals, spark plugs, wiring and other electrical connections from salt, dirt and corrosion. It extends the life of bulb bases and can prevent voltage leakage in every electrical connection. The grease components provide effective protection against burnout at temperatures from -55 °C to +200 °C and are chemically resistant to most metals, organic materials and polymers. The grease forms a thin insulating layer that is resistant to water and moisture and does not attract dust and dirt that could harm the insulation.
