Product Description


AR9200 is a nano tungsten disulfide (WS2) Friction Modifier. WS2 is one of the most lubricious substances in the world. It offers far superior performance to molybdenum, graphite, Teflon® or any anti-wear additive in racing and gear oils. AR9200 penetrates and bonds to metal, wood, rubber, plastic and most surfaces. The lubricating, micro thin film features an ultra-low coefficient of friction (0.03 dynamic; 0.07 static) that prevents sticking and wear. It is ideal for many applications from engines and transmissions to sliding mechanisms and heavy load lubrication environments.

AR9200 can also be used in high temperature and high pressure applications. It offers temperature resistance from -450º F (-270º C) to 1200º F (650º C) in normal atmosphere and from -350º F (-188º C) to 2400º F (1316º C) in vacuum conditions. The load bearing ability of the treated surface is extremely high at over 300,000 psi.


  • WS2 is chemically inert
  • High temperature lubrication protection
  • Very high load properties
  • Practically creates a frictionless surface (COF 0.03)
  • Excellent penetrating abilities
  • Prevents galling, seizing or cold-wielding
  • Long lasting
  • Preassembly applications
  • Fills in surface asperities creating a very smooth and hard surface
  • Dramatically reduces wear
  • Ultra-thin coating (0.05 microns)
  • Suitable for high precision components
  • Non-toxic
Applications Functional Area Operational Conditions Achieved Results
Pins, pinions, gears, bearings Fractional H.P. motors Photocopier drives Eliminated conventional lubricant. Doubled wear life of parts
Piston, piston block, springs Hydraulic pump High speed reciprocating action Extended wear life by 3 times. Eliminated need to heat treat components
Main bearings cam & crank shaft, rod bearings, wrist pins. pistons Automotive engines NASCAR racing, 24 hour endurance racing Operating temp reduced 10%. Engine components showed no wear
Roller index shaft 440 stainless Blood analyzer Constant rotation at high speed, abrupt stop and start Eliminated conventional lubricant. Increased wear 4 times. Stopped galling
Curing rolls & feed rolls Paper mill High speed, 290ºF continuous use Eliminated drag & buildup on rolls. Reduced maintenance by 50%
Medical instruments, ratchet gears Orthopedic ratchet Operating room Eliminated galling and extended wear life 300%
Cutting tool, drills, end mills, jig burrs, reamers Cutting die steel, 440 stainless High speed cutting, high feed rate Tools lasted 5 times longer on average




  • Engine or gearbox - Maximum treatment ratio of 50:1.  1 x 100ml bottle will treat at least 5 litres of lubricating oil.  For engines, bring engine up to temperature and then add AR9200. Idle engine for 15 minutes then drive vehicle normally.
