2,2′-Dimorpholinodiethylether (DMDEE)

Overview

2,2′-Dimorpholinodiethyl ether (DMDEE) is a colorless to light yellow liquid tertiary-amine catalyst. It strongly promotes the water–isocyanate (blowing) reaction with low gelling activity, which gives one-component systems long storage stability.

Also known as

DMDEE; Bis(2-morpholinoethyl) ether; Dimorpholinodiethyl ether
