Methyldiethanolamine | CAS No. 105-59-9 |

Methyldiethanolamine (MDEOA) is a dihydroxy functional tertiary amine. It is a versatile intermediate with a variety of applications.

Coatings

MDEOA is used as a co-initiator for type II photoinitiator combinations. 

As a neutralizing agent, MDEOA increases resin solubility and improves solution stability by reducing pH drift. Additionally, it aids pigment dispersion.

Foams and Elastomers

MDEOA can be used as a chain extender during the synthesis of polyol-based polyurethane foams and elastomers.

Inks

MDEOA is used as a co-initiator for type II photoinitiator combinations. 

As a neutralizing agent, MDEOA increases resin solubility and improves solution stability by reducing pH drift. Additionally, it aids pigment dispersion.

Metal Working

In metal working fluids, MDEOA is used both as a pH buffer as well as an anticorrosion additive.

Textiles

MDEOA forms quat salts with fatty acids which then find application in fabric softener formulations.
