NanoSlick Tungsten Disulfide is extremely lubricious. It does not stick to anything easily and has to be forcefully applied to a substrate to stick. Maximum film thickness possible is 0.5 micron (0.00002″ or 0.02 thou), as one particle of WS2 does not stick to another particle of WS2. There are four different methods for applying Tungsten Disulfide WS2, each method is listed below:

  1. Spray Blasting – this is one of the most acceptable methods and most reliable, however it is also a method not readily available to everyone. It must be done in an enclosed area such as a sand blasting unit so that the powder dust can be contained.
    1. Clean and degrease the part. Cleaner the part, better the coating adhesion.
    2. Sand blast the part with 5 micron Alumina (Aluminum Oxide) powder. Only light blasting is necessary.
    3. Thoroughly clean the part with soft cloth/tissue and completely remove Alumina dust from the part.
    4. Sand Blast the part with NanoSlick WS2 powder @ 120 psi with clean and cold pneumatic air. Spray coat the part till color changes to silver gray.
    5. Lightly dust off NanoSlick WS2 powder dust with clean soft cloth/tissue.
  2. Buffing with Alcohol/WS2 paste – This method too works but takes time and is laborious. Speed and friction determine how effectively the material bonds to the part. The greater the speed and the pressure of application, the greater the bond. For best results use a power tool. A buffing wheel, Dremel tool or even a hone can be used.
    1. Clean and degrease the part.
    2. Mix NanoSlick WS2 powder with Isopropyl (also know as Industrial) Alcohol to make paste.
    3. Apply the paste on part and also on cotton buffing wheel and let it dry.
    4. When paste is dry start buffing the part with buffing wheel.
    5. Continue buffing/Honing till a silver gray coating is seen.
  3. Tumbling or Vibratory Bowl – This method is ideal for bullets and other small parts. Speed and friction determine how effectively the material bonds to the part. The greater the speed and the pressure of application, the greater the bond.
    1. Clean and degrease the part.
    2. Take 5-6 small empty plastic bottles (empty aspirin bottles will do). Put few parts in the bottle and fill the bottle (up to 75%) with NanoSlick WS2 powder. Fill all bottles likewise.
    3. Put the bottles in vibratory bowl/tumbler with sand or vibratory media.
    4. Vibrate/Tumble for 4-5 hours.
    5. Empty the bottles (you can reuse WS2) and wipe clean the parts with soft tissue/cloth.
  4. Use NanoSlick Grease or Oil – this is the least labor intensive method and can be very effective over time. NanoSlick WS2 will slowly get coated on mating surfaces (by pressure rubbing) when parts move.
    1. Clean and degrease the part.
    2. Use either NanoSlick Grease or Oil on parts.
    3. NanoSlick WS2 will slowly get coated on mating surfaces (by pressure rubbing) when parts move.
