An Overview of Molybdenum Disulfide as Dry Lubricant for Coating

Are you tired of using messy, oily coating lubricants that are hard to apply? Well, then you can turn to a technologically advanced and highly effective alternative: the Molybdenum Disulfide (MoS2/ Moly) dry lubricant. One of the most widely used lubricant of this type; MoS2 plays an important role in providing exceptional resistance against corrosion to industrial as well as domestic products.

What are the benefits of using Molybdenum Disulfide for dry coating?

MoS2 is an immensely high performing dry lubricant, thanks to its effective particle size range (1 to 100µm) and a very low friction coefficient (≤ 0.1). While flowing/ moving lubricants cause high friction, loss of energy, and below-par performance, MoS2 provides excellent coating to a product for durability and resistance to wear.

Application of MoS2 can be done in various ways such as physical deposition of vapor, spraying, burnishing, and rubbing. This gives you the choice of applying Moly lubricant as per your convenience and availability of the material for coating.

MoS2 can be combined with binders as well as resins for strengthening effect. This compound also performs very well in vacuum applications as it does not rely on vapor for coating. In fact, you will get best coating results with Moly lubricant when there is no external humidity/ moisture.

Common Applications of Molybdenum Disulphide Dry Lubricant:

MoS2 dry lubricant is used in applications that have high load carrying capacity (up to 250, 000 psi). When factors like operating temperature, presence of external moisture, and coefficient of friction are to be taken in to consideration, then Mos2 coating is an excellent option. Some of the common applications where this compound is used for coating are:

  • Industrial machine tools
  • Compressors
  • Cryogenic pumps
  • Low moisture applications
  • Vacuum applications
  • “O” ring seals
  • Taps and pins

To summarize, Molybdenum disulphide is a reasonable and efficient dry lubricant for various industrial coating applications. With the use of this compound, you can be assured of resistance to corrosion and enhanced durability of your products.
