SULFURIZED ISOBUTYLENE
APPLICATIONS
Sulfurized Isobutylene/T321 /lubricant additive/lubricating oil additive
extreme pressure additive/antiwear additive /oil additive/gear oil additive/metal cutting oil additive
It is yellow transparent liquid with high sulfur content. It has excellent EP performance, oil solubility and low corrosion to metal. It has very good synergy with other additives.It is most used additive for sulfur phosphorus type gear oils, used for blending vehicle & industrial gear oils, metal working oils, drilling machine oils and lubricating grease etc.
FEATURES
Excellent EP and AO properties Low corrosion to metal
Good compatiability with other additives Good oil solubility
RECOMMENDED DOSAGE
1.5-5.0% in lubricating oil.
