Abstract:
PROBLEM TO BE SOLVED: To provide a novel lubricant and a friction modifier containing a solid lubricant and a binding agent as needed in an aqueous medium. SOLUTION: The problem to be solved is appropriate to lubricate steel-steel interfaces (e.g., tractor-trailer couplings, rail-wheel systems and other heavy duty applications). The invention is attained by a composition containing a friction modifier having a high or very high positive coefficient of friction such that the coefficient of friction is considerably higher than that of the solid lubricant. The invention further relates to a composition containing the binding agent and the friction modifier having a high or very high positive coefficient of friction in an aqueous medium.

Abstract:
According to the invention there is provided a liquid friction control composition characterized as either having a high and positive friction characteristic or a low and neutral friction characteristic, comprising a retentivity agent. The liquid friction control composition may also comprise other components such as a solid lubricant, a wetting agent, a consistency modifier, and a preservative. The liquid friction control compositions may be used to modify the interfacial friction characteristics in sliding and rolling-sliding contact such as steel wheel-rail systems including mass transit and freight systems.
