Rokolub AD 246 Ultra is an aryl phosphate ester in the form of a light yellow to colourless liquid with a characteristic, delicate fragrance. It is characterized by low water level and low acid value, which ensure long-term stability of product parameters. In turn, due to the high content of phosphorus, it has properties important for the lubricating oil industry.

Properties and applications

Advantages of Rokolub AD 246 Ultra:

  • improves anti-wear properties of mineral and synthetic oils:
  • application of the product in the amount of 2% in mineral oil brings a reduction in the diameter of the defects in the four-ball test by up to 50%, compared to the base oil without additions,
  • application of the product in the amount of 2% in PAO brings a reduction in the diameter of the defects in a four-ball test, approx. 40%, compared to the base oil without additions,
  • application of the product in the amount of 2% in POE brings a reduction in the diameter of the defects in the four-ball test by over 30%, compared to the base oil without additions,
  • compatible with other anti-friction additives (phosphoric, sulfuric and chlorine ones), which provides good surface protection in sliding contact of materials,
  • does not cause corrosion and staining of metals (in contrast to widely used sulphated and chlorinated AW / EP additives),
  • is compatible with a wide range of oil additives,
  • it is safe for human health.

Benefits of using the product:

  • obtaining oils with better anti-wear and anti-friction properties and extending the life of the equipment,
  • reducing corrosion, compared to oils containing standard AW / EP additives based on sulphur or chlorine,
  • can be used in a package with other additives for oils,
  • increasing safety during production and use of oils.

Applications:

  • industrial oils: hydraulic oils, compressor oils, turbine oils, gear oils,
  • automotive oils: gear oils.
