Phosphate Esters are widely known as effective, ashless, anti-wear and mild extreme pressure additives for lubricants and functional fluids. The primary function of phosphate esters is to reduce friction and wear in applications where high loads cause boundary lubrication conditions. They also enhance sol- Durad® 220B-EP displays excellent anti-wear and extreme pressure performance in laboratory tests. It also shows high resistance to micropitting wear in the FZG test. As a multifunctional additive, Durad® 220B-EP has shown the additional benefits of excellent rust and corrosion protection. It also possesses good solubility and stability in a wide range of lubricant base stocks. They also enhance solubility and stability in a wide range of lubricant base stocks.
