DURAD® 310M is a 100% active phosphate ester multifunctional extreme pressure and antiwear additive for 
lubricants.


APPLICATIONS
The recommended addition level is 0.5-1.0% by weight for formulating in a broad range of lubricant base stocks. A higher DURAD® 310M loading or use in combination with other extreme pressure additives may be required to meet specific lubricant 
requirements. DURAD® 310M has demonstrated excellent 
synergism with sulfur-containing EP additives, making the combination a desirable replacement for chlorinated additives.
FORMULATING WITH PHOSPHATE ESTERS DURAD® 310M displays excellent antiwear and extreme pressure performance in laboratory tests. 
It also shows high resistance to micropitting wear in the 
FZG test.As a multifunctional additive, DURAD® 310M 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.


ENEFITS
• Excellent extreme pressure/antiwear performance.
