Description

Zinc Tetraisopropyl Bis(Dithiophosphate) is an organometallic compound belonging to the zinc dialkyldithiophosphate (ZDDP) family, widely recognized for its exceptional anti-wear and antioxidant properties. This compound is crucial for enhancing the performance and longevity of lubricants and functional fluids under extreme pressure and temperature conditions. It is primarily sought by formulators in the lubricant, metalworking fluid, and industrial additive sectors who require reliable extreme pressure (EP) additives and oxidation inhibitors.

Application

• As a primary anti-wear (AW) and extreme pressure (EP) additive in engine oils, gear oils, and hydraulic fluids.
• As an antioxidant to prevent oil degradation and sludge formation in lubricating oils and greases.
• As a key performance additive in metalworking fluids and industrial lubricants for machining and forming operations.
• In the formulation of specialty lubricants for automotive, aviation, and heavy machinery applications.
• As a corrosion inhibitor and friction modifier in functional fluid packages.
• Used in industrial additive packages to meet stringent performance specifications for OEMs.
