TUNGSTEN DISULFIDE (WS2) | COATING SERVICE
Dicronite® is a tungsten disulfide (WS2), dry film lubricant coating. This extremely thin film coating provides friction and sliding wear reduction in various applications across numerous industries.
Dicronite® is suitable for demanding environments such as extreme temperatures, vacuum, precision tolerances, and many more.
Coat components with Dicronite® to prevent failure, increase efficiency and improve performance.
For 60+ years, Dicronite has been trusted to effectively lubricate:
Have a quick question about your application?
Dicronite® is applied at one of many licensed coating facilities. After surface preparation, Dicronite® dry lubricant is impinged onto the substrate surface at high velocity (similar to sandblasting).
The coating process is conducted at ambient conditions. The material includes no binders or adhesives and requires no curing. Dicronite® can be re-applied to the same component repeatedly.
All metals, most plastics, and some ceramics; may be applied on other coatings/platings
Silver, blue gray, dark gray
0.5 micron (0.00002 inch) or less
Systems with Dicronite® coated on smooth surfaces often range between 0.03 and
0.07 dynamic coefficient of friction, and 0.05 to 0.09 static coefficient of friction
