Tungsten Disulfide Lubricant uses across industries

Benefits and Capabilities of using NanoSlick DT-100 Dry Lubricant 

  • The low friciton coating overcomes or reduces mechanical lubrication problems which improve performance and extend service life.
  • Reduces friction to lower emissions as less fuel is used for a given power level when applied to engine parts such as pistons rings, cams and bores.
  • Eliminates and reduces costly maintenance problems that cause breakdowns and expensive downtime by stopping galling, fretting and friction caused by dissimilar metals and their different hardness factors.
  • Maintains the dimensional integrity of the substrate to within 1/2 micron with no build-up. Tungsten Disulfide (WS2) particles will not adhere to themselves so the coating thickness is limited to 1/2 micron.
  • Withstands loads to 100,000 psi (or load capacity equal to substrate) and operates in the temperature range of -460°F to 1200°F (-273°C to 650°C).
  • Offers 100% Lubricity throughout its texture.
  • Is inert, inorganic, non-toxic, non-distortive, non-corrosive and resistant to most fuels solvents. It is compatible with and enhances the performance of all oils and greases.
  • Resists carbon build-up due to its extremely low co-efficient of friction, less than half that of graphite, Moly (MoS2) and Teflon.
  • Molecularly bonds to all materials and platings and can only be eliminated by removing the bonded substrate.
  • No bakeout or heat curing is required for the application of Tungsten Disulfide (WS2).

Tractors		Tungsten Disulfide (WS2) is an excellent coating for bearings where conventional lubricants can not be used or where the application requires the insurance of a permanent lubricant for extended wear life as in gear motors or transmissions. From miniature bearings used in dental hand pieces to large bearings for electrical power plants, the WS2 low friction coating extends wear life 2 to 5 times. Bearings with the WS2 coating applied by Micro Surface will have a blue-gray color.

Spiral Flow & Mold Release Improvement

A sprial flow study conducted by Western Washington University showed improvements of 3% to 9% in resin flow following Tungsten Disulfide (WS2) coating. The study was conducted to quantify flow enhancement afforded by the Tungsten Disulfide (WS2) coating when applied to injection, blow and extrusion molding/tooling. This return on investment to customers is experienced in improved product quality due to reduced operating pressure and temperatures, as well as significantly lower operating costs resulting from faster cycling and increased tool life.

AMS2530 / DOD-L-85645 Tungsten Disulfide (WS2) Application

AMS2530 is an aerospace material specification that outlines the application of Tungsten Disulfide (WS2) thin lubrication film coating in a binder less impingement applied method that does not require a curing process. Tungsten Disulfide (WS2) has historically been used on metal components and some non-metallic items such as thermoplastics and thermosetting polymers where an extremely thin coating of 1/2 micron in thickness is needed to reduce friction, wear, galling, seizing, and fretting. Tungsten Disulfide (WS2) is compatible with lubricants such a hydraulic fluid, oils, and greases.

  • Raw Material: Must be finely powdered Tungsten Disulfide (WS2) free from contaminants such as graphite, molybdenum disulfide, binders or other materials so as to be compatible in liquid oxygen systems and hard radiation environments. Micro Surface uses the highest quality North American sourced and USA produced Tungsten Disulfide (WS2) in its coating application.
  • Cleaning: Prior to application the components to be coated must be thouroughly cleaned to remove all external substances such as oils, greases, dirt as well as any oxidation and must be handled to prevent re-contamination during the coating process.
  • Application:Tungsten Disulfide (WS2) is impinged on the component at ambient temperature.
  • Adhesion Verification: Micro Surface Corp. verifies the adhesion of Tungsten Disulfide (WS2) by using a pressure sensitive film backed tape that is applied to the sample and rapidly removed in accordance with ASTM D 2510 to confirm that no flakes or particles of the coating are removed exposing the base metal.
  • Thickness: The thickness must be less than or equal to 0.00002 inch (0.5 micron).
  • Thermal Stability: The coating must be able to withstand temperatures in the range of -300°F to 900°F.
  • Appearance: The coating color must be a uniform silver gray color that does not have cracks, pinholes, blisters, or other surface imperfections when viewed under a microscope.
  • Corrosion Resistance: Anodized aluminum panels must not show signs of discoloration or pitting after 500 hours of exposure from ASTM D 2649 testing.
  • Quality: Parts are inspected to ensure proper application, adhesion, & appearance. The coating must be uniform in color, smooth and free from surface imperfections.
