It is conductive grease suitable for transmission of electricity, especially at high voltages. It also conducts heat away from its source and protects the electrical contacts from wear and corrosion. MOSIL EC – 424 forms a very tenacious conductive film on the contact surface permitting very little voltage drops across the contacts and withstanding severe arcing that occurs in high voltage lines. It is thermally stable, oxidation resistant grease suitable for high temperature applications.
