ABSTRACT:
The present invention provides a friction control composition comprising a binder a rheological control agent, and optionally a lubricant. The liquid friction control composition may also comprise other components 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. A method of reducing lateral force, reducing energy consumption, or controlling friction between a metal surface and a second metal surface by applying the composition to metal surface, for example a top of rail or wheel, is also provided. The composition may be sprayed onto the rail surface.
