Abstract
The present invention provides a solid stick composition comprising a thermosetting resin and a grease. Optionally, the solid stick composition may comprise a lubricant, a friction modifier, a thermoplastic plasticizer or a combination thereof. The solid stick compositions may be used for application between two metal surfaces in sliding and rolling-sliding contact such as steel wheel-rail systems including mass transit and freight systems. A method of reducing energy consumption, or controlling friction between a metal surface and a second metal surface by applying the solid stick composition to one or more than one of the metal surfaces, is also provided.
