Abstract
Rheological and physicomechanical properties of epoxy binders based on ED-20 epoxy resin with isoMTHPA and HT-152B (modified isoMTHPA) anhydride hardeners and of a binder based on Ethal-370 modified epoxy resin with Ethal-450 amine hardener have been studied. The pot life of the binders based on ED-20 and anhydride curing agents (isoMTHPA and HT-152B) at 25 °С is quite high. The binders based on Etal-370 and Etal-450 must be preheated before use to 40-60 °C due to the high viscosity. The highest strength of 57.3 MPa was achieved for the composite based on ED-20 and HT-152B.
