Study of the possibility of using Cardura E10P thinner in epoxy compositions

Rheological, physical-mechanical and thermomechanical properties of binders based on ED-20 epoxy resin with Ethal-45M amine hardener and additives of Cardura E10P glycidyl ether from 5 to 50 wt.% as a diluent have been studied. As the Cardura E10P content increases, the dynamic viscosity of the binder decreases significantly and the gel time increases. The tensile strength of cured samples decreases from 49 MPa to 12 MPa with an increase in the Cardura E10P content from 5 to 30 weight parts, the deformability increases from 14 to 38%, and the glass transition temperature decreases from 67°C to 49°C.
