Use as a polyurethane catalyst

DMDEE tends to be used in one-component rather than 2-component polyurethane systems. Its use has been investigated in polyurethanes for controlled drug release and also adhesives for medical applications. Its use as a catalyst including the kinetics and thermodynamics have been studied and reported on extensively. It is a popular catalyst along with

Toxicity

The material has been in use for some time and so the toxicity is generally well understood. However, some sources say toxicity data is limited and work continues to acquire the necessary data and publish to ensure it is in the public domain.
