Description
N,N,N′,N′′,N′′-Pentamethyldipropylenetriamine (CAS 3855-32-1, EC 223-362-3, formula C11H27N3) is a tertiary amine catalyst commercially known as Polycat 77. It carries no assigned E-code and is classified under HS code 29212900 within the broader amines category.
In polyurethane foam production, it accelerates the urethane gel reaction by activating isocyanate-polyol coupling, giving formulators control over cream time and cell structure. It is also used in epoxy curing systems and coatings, where its triamine backbone promotes cross-linking by coordinating with reactive sites across the polymer network.
Pentamethyldipropylenetriamine is supplied as a clear liquid and is subject to REACH registration requirements for import and use within the European Economic Area. Procurement teams should request a current Safety Data Sheet and confirm compliance documentation before ordering. Standard packaging formats vary by supplier volume tier.
