Anti-Galling WS2
Prevent Galling With The Thinnest Dry Film Lubricant
Galling is a form of surface damage arising between sliding surfaces, resulting in seizing and cold-welding. It is a common problem in fasteners, hydraulics, bearings, pistons, air motors and many other industrial operations. The key factors that contribute to galling are friction, heat, pressure and the use of similar materials during installation. Stainless steel threads are prone to seizing, particularly when matched with a stainless hole and will often cold-weld in place. Tungsten Disulfide dry film lubricant is an exceptionally effective solution to galling because it prevents heat build up by the elimination of friction: the source of heat and pressure in the installation process.
Uniform Torque
The coefficient of friction for Tungstenite is 0.035. This lessens the friction between threads and lowers the torque necessary for proper installation.
Stands the Heat
Tungsten Disulfide provides exceptional lubricity in extreme conditions. WS2 withstands temperatures up to 1200° F
Cool Under Pressure
Tungsten Disulfide resists pressure/load capacity up to 100,000 psi or the same as the substrate.
Uniquely Thin
0.5 microns thick properly impinged Tungsten Disulfide is dimensionally insignificant. No extra tolerances need to be considered unlike MoS2 or PTFE
No Interference
Tungsten Disulfide is chemically inert, non-toxic, non-migrating, liquid oxygen compatible with minimal outgassing.
Automotive
Tungstenite in an Internal Combustion Engine
Tungstenite (WS2) is the most effective on the high and low end of the engines performance. By reducing wear on the low end and increasing horse power on the high end.
Applied Tungstenite has been use for years in the primary and secondary automotive marketplace. Applied Tungstenite will improve the viscosity of the primary lubricant, reduces wear, heat on internal engines parts, and transmissions.
Piston Rings
Tungstenite (WS2) works on the Piston rings to reduce or eliminate micro welding to extend the life of the ring, in addition to providing a slippery surface to increase the effectiveness of the engine oil.
Piston Head
Tungstenite (WS2) is applied on the Piston Head to reduce the friction of the initial startup, and warm-up period of the engine. By increasing lubrication for the rings and connecting rod.
Camshaft
The Camshaft in a cold engine is essentially sitting without oil on it so when the engine starts it's starting an un-lubricated part. This is when the camshaft is subjected to the most amount of wear. Tungstenite (WS2) eliminates this problem because the Tungstenite is impinged on the camshaft so it is never without lubricant.
Racing Engines
When Tungstenite (WS2) was applied to the main bearings, cam & crank shafts, rod bearings, wrist pins, and pistons in engines used in NASCAR and 24 endurance racing. There was a reduction in operating temperature of 10%, there was almost no wear on the coated components and there was increase power on the top end.
