EP/AW additives

Extreme pressure/anti-wear additives for emulsion-type MWFs

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.

Extreme pressure/anti-wear additives for fully synthetic MWFs

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.

Product highlights

  • Hordaphos 145

    Hordaphos 145 is an efficient EP/AW additive with emulsification as well as corrosion inhibiting properties for ferrous metals and aluminium alloys. It is used for metal working fluids (emulsions, semi-synthetic, neat oil), rolling emulsions and fire-resistant hydraulic fluids (HFA-E). Performance depends to some extent on the amine chosen for naturalization and can be boosted by combining it with esters, especially TMP-trioleate.

  • Hostacor ITD

    Hostacor ITD is a versatile performance additive for metal working fluids and lubricants. Besides of being an effective EP/AW additive, it provides excellent corrosion protection for steel and aluminum alloys while reducing copper and cobalt leaching. Hostacor ITD is recommended for metal working fluids (emulsions, semi-synthetic neat oil), rolling oils & emulsions, fire-resistant hydraulic fluids (HFD, HFD-U) and gear oils.

Fully synthetic – product highlights

  • Hordaphos MDB

    Hordaphos MDB is an efficient EP/AW additive for aqueous metal working fluids and water-based fire-resistant hydraulic fluids (HFC, HFA-E).

    more
  • Hostaphat AKT Liq.

    Hostaphat AKT Liq. is an ethoxylated phosphate ester that is water soluble and provides efficient EP/AW additive as well as corrosion inhibiting properties for aluminum alloys. It is used for metalworking fluid formulations, specifically synthetic or water-based metalworking fluids. Hostaphat AKT performs very well as a corrosion inhibitor for non-ferrous metals, including but not limited to aluminum, copper, and brass. It is a very effective in-can corrosion inhibitor for aerosol containers and works synergistically with Genamin CH 020 to reduce cobalt leaching in metalworking fluids. Typical treat rates range from 0.5-3.0 % in the concentrate.
