D.E.H 39 Aliphatic polyamine Dow Chemical Crosslinking / Coupling / Curing Agents >> Amines /Amides >> aliphatic Epoxy (EP) ADHESIVE D.E.H.* 39 epoxy curing agent is a liquid aliphatic polyamine curing agent. D.E.H. 39 resin is a low viscosity aliphatic polyamine based on aminoethylpiperazine (AEP). D.E.H. 39 curing agent provides a short pot life and cures in minutes with liquid epoxy resins. Similar in application to D.E.H. 20, 24, 26 and 29 epoxy curing agents, D.E.R. 39 curing agent is used for maintenance paints, 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. 39 curing agent is used for casting, potting and encapsulation. D.E.H. 39 curing agents is often used for epoxy composite materials. Adhesives Lows cost aminoethylpiperazine curing agent. Provides short pot life and cures in minutes with liquid epoxy resins. Used in adhesives.
