Experimental winding of three batches of fiberglass rods was performed on a production line. The optimal composition of EDI binder was selected with component weight ratios ED-22/IMTGFA/UP-606/2 =100/85/(1.5 – 3), which raises the glass transition temperature of the products by 10 – 15°C in comparison with the control samples. The increase in the glass transition temperature was confirmed by means of TMA and DSC in all three pilot batches manufactured at different times. The heat-treatment temperatures 35 and 40°C for the new EDI composition in an impregnating bath are proposed to increase the viscosity, which provides 15% weight content of the binder in fiberglass, which meets the regulatory code specifications.
