EP/AW additives

Clariant offers a broad range of phosphorus acid ester based extreme pressure/anti-wear additives.

These additives are multifunctional, because not only they are EP/AW, but also – depending on the type - they are emulsifiers and/or corrosion inhibitors.

The broad portfolio of EP/AW additives for emulsion-type MWFs contains esters with different P content and different fatty alcohols and degrees of ethoxylation for all kind of formulation purposes.

In addition, some of them also offer excellent corrosion protection on aluminum.

The water miscible MWFs must be water dispersible or water soluble, and this is assured by our range of products. You can find our selected additives in the products highlight section below.

Clariant’s phosphorus compounds as extreme pressure and anti-wear (EP/AW) additives for fully synthetic MWFs assure water solubility, low foaming and excellent performance under extreme lubrication conditions.

The EP/AW additives must be clearly soluble in water in order to provide a clear solution which allows high stability and good visibility of the operation.

Our team has screened for additives that not only offer excellent EP/AW performance but also are water soluble. The two selected products are Hordaphos MDB and Hostaphat AKT liq. – see the section below for more details.
