D.E.H.® 26

D.E.H.® 26 Curing Agent is an economical liquid aliphatic polyamine hardener, tetraethylenepentamine (TEPA), that offers a short pot-life and cures in minutes with standard unmodified liquid epoxy resins. Similar to D.E.H.® 24 Epoxy Curing Agent in application, it provides lower vapor hazard to workers due to its higher boiling point. D.E.H.® 26 Epoxy Curing Agent is used for maintenance paints, the manufacture of epoxy-amine adducts, in adhesives, and civil engineering applications. It is also used as an accelerator for polyamide curing agents. In electrical applications, D.E.H.® 26 Curing Agent is used for casting, potting and encapsulation.
