Description
Bis(3-dimethylaminopropyl)amine, CAS 6711-48-4, is a tertiary diamine commercially available under the trade name Lupragen N 109. It carries EC number 229-761-9 and is classified under HS code 2921.29.0055 within the aliphatic polyamine family.
In polyurethane foam production, it functions as a reactive amine catalyst, accelerating the urethane gel reaction to control cell structure and rise profile. It also serves as a curing agent and cross-linker in epoxy coatings and adhesive formulations, where its bifunctional amine groups react with epoxide groups to build network density and improve adhesion strength.
This product is supplied as a clear liquid and is subject to REACH registration requirements within the European Economic Area. Procurement teams should confirm SDS compliance and substance registration status with the supplier prior to ordering. Standard industrial packaging formats apply; contact your regional account manager for volume and lead time details.
