Advantages of Tungsten Disulfide Coating

Tungsten disulfide coating is widely used in automobile industry, medical equipment, plastic industry and other fields. It is favored by most customers. It has brought considerable economic benefits to the industries and enterprises, which is inseparable with its own advantages.

Every piece of equipment is prone to friction in its operational life. Friction affects in two ways: it improves performance when applied in the right amount, and causes wear and tear when exceeds beyond acceptable limits. Friction between two parts increases in extreme environments comprising high temperature and pressure. Under this condition, tungsten disulfide coating helps reduce friction between moving parts, and contributes to better service life of the equipment.

Tungsten disulfide coating has these main advantages:

(1) Low coefficient of friction: This coating exhibits a low coefficient of friction, which is 0.03 for dynamic, and 0.07 for static friction.

(2) Helps avoid carbon build-Up: The low coefficient of friction helps avoid carbon build up better than teflon, graphite, and molybdenum disulfide (MOS2).

(3)Ideal for extreme conditions: This dry film coating can withstand loads to 10,000 PSI (load capacity equal to the substrate), and has an operating temperature that ranges from -460°F to 1200°F.

(4) Improves service life: The tungsten disulfide coating helps prevent seizing, galling, fretting or cold- welding of components or machine parts. This helps reduce maintenance problems, expensive part replacement, downtime, and other issues.  

(5)Compatible with most oils and greases: tungsten disulfide is compatible with most oils and greases, and maintains a hydrodynamic layer.

(6)Easy application: The dry film coating is easy to apply and requires no heat curing, or bake out. It can be applied over metal parts easily without any chemical agent or binder. It will not peel because it assimilates into the substrate easily.

(7)Excellent chemical stability: tungsten disulfide is non-toxic, non-corrosive, and inert. It responds with most metal substrates. It cannot tolerate solvents, chlorinated solvents, and refined fuels.
