What is Molybdenum Disulphide?

Molybdenum does not occur naturally as a free metal on Earth but is instead found in various oxidised states within minerals. Molybdenum Disulphide is a compound containing Molybdenum and Sulfur, which takes the form of a crystalline mineral which is silvery grey in appearance. Molybdenum Disulphide is used as a solid lubricant and anti-wear barrier coating in high pressure and high temperature applications. A number of different branded coating options have used Molybdenum Disulphide as their base which includes Everslik, Molykote and Moly-Mist.


Molykote D-7409 is an anti-friction coating, the material itself is a heat curing fry film lubricant with a high load capacity. It is suitable for both high temperature and high wear applications and its primarily used as a form of lubrication where grease cannot be used. Molykote D-7409 provides a protective barrier from a range of sources including Oil, Brake Fluid,Detergents. It will protect against Acids but not Alkalis. Molykote is very popular within the automotive industry and applications include Piston Rings and Tappets within combustion engines, Brakes, Locks, Hinges and also Oil Pumps.


Moly-Mist is similar in nature to Molykote in that it is primarily used as a dry lubricant to lower friction and prevent galling, it also enhances corrosion resistance. It is often used within moving components within machines such as Gears, Dies, Taps, Chains, Pistons and Plungers. Moly-Mist is probably best suited as a direct replacement to grease and will not offer the same level of wear or corrosion protection as the other processes on this list.
