A Study of the Rheological, Physicomechanical, and Thermomechanical Properties of Epoxy Binders with Various Curing Agents

The rheological, physicomechanical, and thermomechanical properties of the binders based on an ED-20 epoxy resin and KhT-152 B, Etal-450, and Iso-MTHPA curing agents have been studied. The rheological properties of binders are practically comparable. The KhT-152 B binder-based compound exhibited the...

Zusammenfassung:	The rheological, physicomechanical, and thermomechanical properties of the binders based on an ED-20 epoxy resin and KhT-152 B, Etal-450, and Iso-MTHPA curing agents have been studied. The rheological properties of binders are practically comparable. The KhT-152 B binder-based compound exhibited the highest durability. The Iso-MTHPA based binder exhibits the highest tensile strength among all studied compounds. The studied binders are comparable in terms of thermomechanical properties, and their glass-transition temperature is 100–110°C.
