Huntsman Capabilities 

Huntsman is a major integrated supplier of amines, many 

of which have applications in the metalworking industry. 

We have developed and continue to support our amine 

process technologies in fully equipped laboratories and 

pilot facilities in Europe and the United States. 

Huntsman Products 

Amines are an important component of metalworking fluids 

and in metal cleaning applications where they provide 

essential properties including corrosion inhibition and are a 

source of reserve alkalinity. 

The following is a brief introduction to those products which 

are specifically recommended for use in metalworking.

AMINES FOR METALWORKING 

Ethanolamines 

Ethanolamines provide alkalinity and corrosion control to 

metalworking fluids. Amine selection is based on metals 

encountered, misting concern, toxicity, alkalinity requirements 

and stability.

the formulation of metalworking fluids, where they provide 

alkalinity control and corrosion inhibition.

DIGLYCOLAMINE® Agent 

DIGLYCOLAMINE® Agent is a primary amine specifically 

recommended for use in the manufacture of metalworking 

fluids where it can be used as an alternative to 

diethanolamine. The product is stoichiometrically equivalent 

to diethanolamine and offers similar buffering 

capacity, with salts offering improved hard water tolerance. 

The product is non-volatile and has a low tendency 

to leach copper, aluminium and cobalt (see figure 1). 

DIGLYCOLAMINE® Agent has low acute toxicity and 

has low toxicity to aquatic species. DGA® Agent is 

non-mutagenic in “in vitro” systems and has low 

nitrosamine potential. While the product is classed as 

corrosive to the skin and eyes, similar to other strong 

amines, it is not a dermal sensitizer. 

BHEMA 

BHEMA is a tertiary amine recommended for use in the 

manufacture of metalworking fluids where it can be 

used as an alternative to triethanolamine. The product 

is a slightly stronger amine than triethanolamine which, 

in combination with a lower molecular weight, results in 

reduced usage levels for any required pH. BHEMA may 

be used as a single amine, reducing the need for a second 

primary amine such as monoethanolamine. The 

product is non-volatile, has good copper and cobalt 

leaching characteristics (see figure 1) and has a lower 

tendency to stain aluminium than triethanolamine. 

BHEMA has low mammalian and aquatic toxicity, has low 

nitrosamine potential, and is not classified as corrosive.

SURFONAMINE® MW-781 Amine 

SURFONAMINE® MW-781 amine is a primary amine 

recommended for use in the manufacture of metal 

working fluids. The product is a versatile additive for 

use in synthetic and semi-synthetic products where it 

offers multifunctional properties. In addition to being a 

strong primary amine, salts of which tend to be low 

foaming, the product also acts as a coupling agent and 

has the potential to be a vapour phase corrosion 

inhibitor. 

POLYETHERAMINES 

Huntsman manufactures a wide range of polyetheramines, 

many of which find application in the formulation 

of metalworking fluids, the following products 

are specifically recommended: 

• JEFFAMINE® D-2000 is a hydrophobic polyether 

diamine which acts as a defoamer in semi-synthetic 

and synthetic metalworking fluids. 

• JEFFAMINE® T-403 is a low molecular weight 

polyether amine containing three primary amine 

groups. It offers low tendency to leach cobalt from 

tooling and provides added lubricity.
