Additional MoS2 Coating Methods

The first method describes how the MoS2 coating can be applied by high speed impingement. The second method discusses combining the coating with a paint-like substance.

  1. Impingement Coating Method (AMS2526): MoS2 can be applied as a fine powder to a coating thickness of less than 0.0001” utilizing this method.
    • This method requires specialized equipment to obtain the desired results.
    • Please contact us at info@ws2coating.com for more information on this coating method and how it can benefit your application.
    • This method generally does not affect machine tolerances and can provide long term lubrication in extreme environments. It can be used as a primary lubricant or can be used in conjunction with oil and/or grease to extend equipment life, prevent galling, seizure and fretting.
  2. MoS2 As A Paint-like Coating (MIL-PRF-46010, AS5272 and more): MoS2 is often used as an additive with certain types of resins and binders to form a paint-like coating. Depending on the substrate and coating material, the required curing process will either be Air or Heat cured.
    • Typical thickness of this coating is 0.0002 – 0.0007”
    • The coating process, from surface preparation and application to curing will vary from the type of coating required and the manufacturer
    • Obtain the manufacturers application instructions prior to starting your project.
