Durad® 48

Durad® 48 is a trialkyl phosphate anti-wear and extreme pressure additive for industrial oils. Neutral trialkyl phosphates significantly improve the anti-wear/extreme pressure properties of mineral and synthetic oils. However, unlike triaryl phosphates, they contain no phenolic species and may therefore be preferred for use in applications where there is concern about the potential release of the oil into the environment.

Product Applications

DURAD® 48 is used as antiwear/extreme-pressure additive in both synthetic and mineral oil base lubricants. Traditionally, phosphorus-based AW additives have been based on acid alkyl phosphates and phosphites. The acid phosphates and phosphites, while very active, have several disadvantages for example they; are difficult to handle, can cause corrosion, hydrolyse readily, are sensitive to hard water, will interact with other additives (e.g. basic/overbased additives). The trialkyl phosphates do not suffer from the above problems and therefore offer advantages as neutral products, free from phenolic compounds.
