Product Description
Diethylaminoethanol (DEAE) is a clear liquid. It is used as a neutralizing amine for boiler water, coatings, etc.

The ideal vapor pressure and vapor-liquid distribution properties of DEAE make it the best choice for pH adjustment of process water.

Beyond its application in the water treatment segment, DEAE is also used as a neutralizing amine for indrustrial coatings and an intermediate for various surfactants.
