D.E.H 26 Aliphatic polyamine Dow Chemical Crosslinking / Coupling / Curing Agents >> Amines /Amides >> aliphatic Epoxy (EP) ADHESIVE D.E.H.* 26 epoxy curing agent is a liquid aliphatic polyamine curing agent. D.E.H. 26 curing agent is a low cost, aliphatic polyamine hardener, tetraethylenepentamine (TEPA), that provides a short pot-life and cures in minutes with liquid epoxy resins. Similar to D.E.H. 24 epoxy curing agent in application, it provides a lower vapor hazard to workers due to its higher boiling point. D.E.H. 26 epoxy curing agent is used for maintenance paints for the manufacture of epoxy amine adducts, in adhesives, civil engineering applications and as an accelerator for polyamide curing agents. In electrical applications, D.E.H. 26 curing agent is used for casting, potting and encapsulation. Adhesives Lows cost tetraethylenepentamine curing agent. Provides short pot life and cures in minutes with liquid epoxy resins. Used in adhesives.
