What is Dimorpholinodiethyl ether?
Dimorpholinodiethyl ether (CAS 6425-39-4), abbreviated DMDEE, is a tertiary amine compound used as a reactive catalyst in polyurethane and polymer systems.
Where is Dimorpholinodiethyl ether used?
- One-component polyurethane sealants: primary catalyst for moisture-triggered curing
- Construction and building products: cure performance in roofing membranes, joint sealants and gap fillers under variable humidity
- Polyurethane foam systems, including spray foam insulation: balances gel and blow reactions for control over cell structure and rise time
- Elastomers and coatings: crosslinking with controlled cure onset
- It accelerates curing reactions without requiring post-cure removal.
Commercial specifications
- Liquid at standard commercial purity levels, typically 98% or higher
- Packaging from drums to IBC totes, with bulk options depending on volume
