PRODUCT DESCRIPTION
Disulfide (WS2) or Molybdenum Disulfide Coating is an extremely slick, dry film lubricant coating. WS2 has an extremely low coefficient of friction of 0.03 -- lower than that of Teflon, Graphite, or Molybdenum Disulfide (MoS2). The film is remarkably durable compared to many other lubricant materials and can withstand tremendously high loads of over 300,000 psi! WS2 has unsurpassed performance properties for lubricity, non-stick, low drag, wear life, and load rating. WS2 is an excellent release material for plastic molds, extrusion dies, and other release applications. WS2 can eliminate the need for liquid lubricants or can be used with petrochemical oils, greases, synthetic oils, silicone lubricants, and hydraulic fluids. It has an affinity for lubricants and maintains a hydrodynamic layer. It helps to hold oils or greases on the surface, increasing lubrication even more. At only 0.5 microns (0.000020”) thick, the coating can be applied to high-precision parts without tolerance problems. WS2 is also a fairly inert and non-toxic material that has been used in medical device and food processing applications. It is applied to customer substrates by an ambient temperature high velocity process. It will not anneal or warp substrate materials.WS2 can also be used alone, or in combination with our PVD hard coatings for even greater durability!
