Abstract
A composition for increasing adhesion between two surfaces that are in traction, sliding or rolling-sliding contact with each other is provided. The composition comprises one or more than one first component, where each of the one or more than one first component has a Mohs hardness value of equal to or greater than 7, and one or more than one organic rheology additive. The one or more than one first component and the one or more than one organic rheology additive are present in a ratio from about 90:10 to about 99.9:0.1 (wt/wt). The composition does not comprise water. A method of increase adhesion between two steel surfaces in sliding-rolling contact is also described. The method involves applying the composition to the rail surface at a rate sufficient to increase the adhesion between the two steel surfaces.
