Rokolub AD 246 ultra is an essential anti-wear and anti-friction additive for lubricants dedicated to devices operating at high temperatures. Thanks to its use, the friction between the moving parts is reduced, which reduces the wear of the equipment. In addition, the product prevents machine wear in the event of a load resulting in boundary friction.

Properties and applications

Advantages of Rokolub AD 246 ultra:

  • improves the anti-wear properties of mineral and synthetic oils
  • interacts with other anti-seizing additives (phosphorus, sulphur, chlorine), which allows to obtain a good surface protection in sliding contact
  • unlike the widely used sulphated and chlorinated additives AW/EP, it does not cause corrosion or metal colouring
  • is compatible with a wide range of oil additives
  • it is safe for human health and environment
  • no GHS statements

Benefits of using the product:

  • obtaining oils with better anti-wear and anti-seizing properties, and extending the service life of the equipment
  • reduction of rust compared to oils containing commonly used additives AW/EP based on sulphur or chlorine
  • possible to be used in a package with other oil additives
  • increased safety during production and use of oils


  • industrial oils: hydraulic oils, compressor oils, turbine oils, gear oils;
  • industrial greases
  • metal wroking fluids
