How does Dry Film Lubricant – per MIL-PRF-46010 and AS5272 differ from other dry film lubricants?

Unlike our other Dry Film Lubricants, Tungsten Disulfide (WS2) per Process SL-39 and Molybdenum Disulfide (MoS2) processed in the same manner (DOD-L-85645 Type 1), this process requires the use of resins, binders, and a heat curing process. While it is slightly thicker, it also offers the advantage of corrosion protection in addition to lubricity.

This bonded dry film lubricant starts out as a high-performance, paint-like coating consisting of fine particles of a lubricating pigment (Molybdenum Disulfide) blended with binders and proprietary additives. After application and proper curing, these lubricants bond to the substrate to create a solid film lubricant which reduces friction greatly increases wear life, and offers exceptional corrosion protection in harsh environments.

Which are the major and noteworthy application areas of dry film lubricant MIL-PRF-46010?

This solid film lubricant per MIL-PRF-46010 has been used in a wide variety of areas, including but not limited to:

  • Parts operated in a corrosive environment
  • Parts stored for long periods of time
  • Where permanent lubrication is desired (inaccessible parts)
  • Where operating parameters exceed the load-bearing capacities of ordinary oils and greases
  • For parts subject to frequent disassembly
  • Where the clean operation is desired, it will not attract dirt and debris like regular oils and greases
  • Where a protective coating and sacrificial break-in lubricant are desired
  • Where fretting and galling are a problem (splines, universal joints, keyed bearings etc.)
