D.E.H.® 20

D.E.H.® 20 Epoxy Curing Agent is an economical, liquid diethylenetriamine (DETA) aliphatic polyamine hardener that provides a short pot-life and cures in minutes with standard unmodified liquid epoxy resins. D.E.H.® 20 Epoxy Curing Agent is used for civil engineering applications, maintenance paints, and in the manufacture of epoxy-amine adducts. It is also used in adhesives, epoxy composite applications and as an accelerator for polyamide curing agents. In electrical applications, D.E.H.® 20 Epoxy Curing Agent is used for casting, potting and encapsulation.
