  • Features



Compatible with high temperatures (1400°C)
Excellent load-carrying capacity and seize protection
Sulphur content of less than 250ppm, with a total halogen content (including chlorine) of less that 20Oppm
Low seepage, so it can be used in places wherein cleanliness is required
Allows screws to be removed easily even after extended periods of use at high temperatures
Does not include components that become brittle at high temperatures


Prevents seize of screws used at high temperatures.
Aprroved for use by many manufacturers of set screws used in power plant turbines, and manufacturers of steam valve joints

It is used in friction

  • Sliding bearings
  • Sliding guideways
  • Threaded connections
  • Spline / key joints


  • Cold resistance
  • Termal (heat) resistance
  • Very high load carrying capacity
  • Good adhesion strength
  • Emergency properties
  • Avoidance of stick-slip
  • Provides constant torque for threaded connections
  • Nickel-free
  • Lead-free
  • Easy mounting / dismounting

Problems to be Solved material

  • Seizure
  • Stick-slip motion
  • Lubricants leaking off or emission due to centrifugal forces
  • Frequent re-lubrication
  • Difficult mounting / dismounting
  • Unstable torque because of wide range friction coefficient
