T-butyl phenyl phosphate CAS:78-33-1

What is PSAIL 3220B?

PSAIL 3220B is a highly effective ashless extreme‑pressure (EP) and anti‑wear additive based on a tert‑butyl phenyl phosphate ester structure. It is primarily used to reduce friction and wear under high‑load boundary lubrication conditions, effectively extending equipment service life and lowering energy consumption. This additive exhibits excellent synergistic effects with other sulfur, phosphorus, and chlorine‑based EP/anti‑wear agents while providing certain corrosion inhibition and oxidation resistance properties. It demonstrates good solubility in both mineral and synthetic base oils. Widely used in industrial oils (e.g., gear oils, hydraulic oils), metalworking fluids and greases. It is also widely used as the base oil for high‑performance, fire‑resistant hydraulic oil.
