This product is made from diphenylamine and olefins as raw materials, which are alkylated, refined, and filtered to obtain a light yellow transparent liquid. The use of this product in internal combustion engine oil can effectively control the viscosity growth of the oil, and it can also be applied as an antioxidant in other industrial oils and polyurethane materials.
It has excellent high-temperature oxidation resistance and oil solubility, making it an ash free antioxidant;
It has excellent high-temperature thermal stability;
It has good compatibility and antioxidant synergistic effect when combined with other aromatic amines and shielding phenolic antioxidants.
Used for modulating high-end general-purpose internal combustion engine oils. Reference dosage: 0.3~1.0%
Used for modulating turbine oils, heat transfer oils, hydraulic oils, and lubricating greases. Reference dosage: 0.1~0.5%
Used for fuel oils. Reference dosage: 0.1~1.0%
