AtomLube Ultra Dielectric Grease

ULTRA dielectric grease

AtomLube Ultra Dielectric Grease's silicone-based composition is designed to prevent voltage leakage around electrical connectors. Formulated with a nano-engineered additive, AtomLube provides better protection from water and environmental contaminants than a conventional dielectric grease, keeping electrical components insulated from corrosion for long periods of time. It also has an extended range of low- and high-temperature resistance, making it ideal for use in severe operating conditions.

AtomLube Ultra Dielectric Grease is specifically designed for electric contact, connectors, switches and sensors in automotive and trucking applications. Because it's an inert grease with excellent high temperature performance, it can be used for lubricating o-rings, gaskets, valves and seals as well as surfaces that require stable lubrication over long periods without drying out. This grease is also an excellent lubricant on rubber, plastic and ceramic surfaces.
