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.

在一条生产线上进行了三批玻璃纤维棒的实验缠绕。选择EDI粘合剂的最佳组成，组分重量比为ED-22/IMTGFA/UP-606/2 =100/85/(1.5 – 3)，使产品的玻璃化转变温度提高10 – 15°C与对照样品的比较。在不同时间制造的所有三个中试批次中，玻璃化转变温度的增加通过 TMA 和 DSC 确认。建议将新 EDI 组合物在浸渍浴中的热处理温度设为 35 和 40°C，以增加粘度，从而在玻璃纤维中提供 15% 重量含量的粘合剂，符合法规规范。
