Duraphos™  - Antiwear additives for oil
Duraphos® Series

Duraphos® 178

Antiwear Additives Specifically Designed for Oil Lubricants

An Antiwear/Extreme Pressure Agent with Copper Corrosion Protection

Duraphos®️ 178 demonstrates outstanding antiwear performance with extreme pressure capability and copper corrosion protection. Typically, it is used in drivelines and industrial lubricants including greases. Friction level meets requirements in transmission systems. It is approved in lubricants with incidental food contact.


Features and Benefits
