What is Bis(dimethylaminoethyl) ether?
Bis(dimethylaminoethyl) ether (CAS 3033-62-3), also known as BDMAEE, is a tertiary amine catalyst used primarily in polyurethane foam production. Also marketed as NIAX Catalyst A1 and NIAX A99.
Where is Bis(dimethylaminoethyl) ether used?
- Flexible slabstock and molded foam: strongly promotes the water-isocyanate blowing reaction, allowing reduced total catalyst loading
- Rigid foam insulation panels and spray foam: balances reactivity profiles and improves dimensional stability in the cured product
- Adhesives and sealants: cure accelerator for fast gelation at low dosage
- In elastomer casting systems it provides controlled open time and surface cure.
Good to know: It accelerates the urethane and blowing reactions, which govern foam rise and cell structure. High-activity, low-odor alternative to standard amine catalysts.
Commercial specifications
- Drum and IBC quantities
- Technical grade, purity commonly 98% or above
- Pre-diluted or blended catalyst formulations offered by some suppliers
