Effective Temperature Range : 150 °C
to 450 °C
Applications
:
OCN
363 is an effective Antioxidant for:
# Gasoline &
Diesel Engin0e Oils
# Industrial Oils
# Automotive/Industrial Greases
# Fuels (H.S.D. & M.S.)
Advantages over
conventional Antioxidants:
Working
range: It
works upto 450°C whereas DBPC dissociates above 110 °C and other conventional
antioxidants have limited working temperature range.
Compatibility:
Good compatibility with all other types of additives and gives synergistic
effect along with Aminic, Phenolic and
Phosphates type antioxidants.
