Molybdenum disulphide is a natural mineral with layered lattice structures. The individual layers are only connected by van der Waals forces, which supports simple relative movement. This intrinsic property makes it possible to achieve a permanent and maintenance-free friction reduction even under very high loads.

MoS₂-based bonded coatings form an intermediate layer to the sliding partners both when dry and when additionally lubricated with oils or greases. This thin, stable transfer film on the mating partner results in a significant reduction in the coefficient of friction and wear protection of the surfaces involved. The transfer film adapts to the topography and the load conditions. This increases the load-bearing proportion of the contact surfaces and reduces the stress conditions. This property is dynamic, adapts to the requirements and is therefore in contrast to a classic hard material coating.

Molybdenum sulphide is a semiconductor with a grey-black color. There are MoS₂ dry lubrications that contain both organic and inorganic binder systems. The typical layer thicknesses of bonded coatings are in the range of 10 to 30 µm.
