T557 Octyl/Butyl Diphenylamine

Description
T557 is octyl/butyl diphenylamine and an excellent liquid antioxidant. This antioxidant can effectively control the increase of oil viscosity, particularly in high quality internal combustion gasoline engine oils. It can also be used in general-purpose in industrial oils.

Special features
■ Fine antioxidation at high temperature
■ Fine compatibility. Enhancing the antioxidant effect when combined with antioxidants of phenylamines, phenyl α-naphthylamines and hindered phenols
■ Fine high temperature thermal stability

Applications
Used for blending high grade engine oils. The dosage: 0.3-1.0%
Used for blending turbine oil, transfer oil and hydraulic oil and industrial oils.The dosage: 0.1-0.5%
Used for fuel oils. The dosage: 0.1-1.0%
