Rokolub AD 232 is an aryl ester of phosphoric acid (V) in the form of a light yellow to colourless liquid with a characteristic, delicate fragrance. In the presence of water and an acidic or alkaline environment, a hydrolysis reaction occurs, which is typical for this group of chemical compounds. In order to ensure hydrolytic stability, the product has a very low water level and a low acid value which limits its hydrolysis. Rokolub AD 232 also has a high content of phosphorus, which is responsible for the unique properties of the product.

Properties and applications

Advantages of Rokolub AD 232:

 – 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 of 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 more than 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 the 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 oil additives;

 – increased safety during production and use of oils;

Applications:

 – industrial oils: hydraulic oils, compressor oils, turbine oils, gear oils;

 – automotive oils: gear oils;
