SOLID LUBRICANTS & FRICTION MODIFIERS FOR HEAVY LOADS AND RAIL APPLICATIONS

摘要

The present invention relates to novel lubricant and friction modifier compositions optionally comprising a solid lubricant and a banding agent in water medium suitable for lubricating steel-steel interfaces such as tractor-trailer couplings, rail-wheel systems and other heavy duty applications. The invention also relates to compositions described above which include friction modifiers with high or very high and positive coefficients of friction such that the coefficient of friction is considerably higher than the solid lubricant. The invention further relates to compositions comprising a binding agent and a friction modifier with a very high and positive coefficient of friction in a water medium.
