N,N-Dimethyldipropylenetriamine

N,N-Dimethyldipropylenetriamine (CAS 10563-29-8, EC 234-148-4) is a triamine compound commonly referenced under the abbreviation DMAPAPA and known in adhesive formulations as Araldite 2011B. It carries no assigned E-code and belongs to the aliphatic amine chemical family.

In epoxy curing systems, DMAPAPA functions as a hardener by reacting with epoxide groups to form crosslinked polymer networks, directly influencing cure speed and final mechanical strength. It also serves as a corrosion inhibitor in metalworking fluids and water treatment programs, where its amine groups coordinate with metal surfaces and chelate dissolved ions to suppress oxidative degradation.

This product is supplied under REACH compliance for the European market and is available in standard industrial drum and IBC packaging. Buyers should confirm grade specifications and SDS documentation with the supplier prior to procurement, as purity and formulation-specific requirements vary by application.
