General description

4,4′-(Oxydi-2,1-ethanediyl)bismorpholine (DMDEE) is an amine based catalyst that is also known as dimorpholino-diethyl ether. It can act as a catalyst for blowing reactions and facilitates the process of polymeric curing.

Application

Catalyst for flexible polyester foams, molded foams, and moisture-cured foams and coatings. Good blowing catalyst that does not cause cross-linking.
DMDEE can be used as a property modifier for 3-nitribenzonitrile (3-NDN) which can be further used in matrix assisted ionization vacuum analysis (MAIV). It can also be used as catalyst for formation of polyurethane foams, adhesives and polypropylene glycol (PPG) incorporated fumed silica.
