N,N-Dimethyldipropylenetriamine (DMDPTA, DMAPAPA) is a liquid short-chained polyamine.
N,N-Dimethyldipropylenetriamine carries primary, secondary and tertiary amine functionalities. Therefore, it is mainly used as epoxy and polyurethane catalyst (via the tertiary amine) and as a hardener / crosslinker for epoxy (via the primary and secondary amine).
Epoxy resins that are hardened by N,N-Dimethyldipropylenetriamine are mainly used in areas of applications like adhesive, coatings and paints.
N,N-Dimethyldipropylenetriamine is a fast and efficient epoxy hardener suitable for cold curing applications. Kinetics, Tg and mechanics comparable to AEPIP
(N-aminoethylpiperazine) and TETA (Triethylenetetramine).
N,N-Dimethyldipropylenetriamine´s performance can be adjusted via parts by weight (pbw). It cures highly efficiently with 7,5 pbw. The accelerating effect observed even at a low EEW ratio. A longer gel time, but higher Tg is reached with less DMAPAPA.
