ABSTRACT:
An electric contact lubricant is disclosed which comprises a predominant amount of an evaporable solvent and a lubricant which, in turn, comprises a predominant amount of a partially crosslinked polyol ester formed by esterification of an aliphatic monocarboxylic acid with an aliphatic polyol in the presence of a dibasic acid crosslinker, a lesser amount of a phosphate ester fluid, and one or more corrosion and oxidation inhibitor compounds.
