Description
Summary:This invention relates to a method and composition for improving the corrosion resistance and anti-wear properties of synthetic lubricating oil greases comprising the addition to said greases of effective amounts of a chelated Schiff base derived from the condensation of approximately stoichiometic amounts of at least one aldehyde and a polyamine. Supersedes PAT-APPL-700 373, AD-D015 694.
