This additive is an amine-neutralized phosphate ester compound, functioning as a non-ash-forming multifunctional additive with extreme pressure (EP), antiwear, and corrosion inhibition properties. It improves the FZG load-carrying capacity of lubricating oils and enhances the frictional characteristics of greases. When blended with tricresyl phosphate (TCP), it exhibits synergistic EP and antiwear effects.
