焦油聚氨酯有毒、怕水、抗老化能力差 ,采用无莫卡固化剂 ,可以降低毒性 ,能在潮湿面施工。彩色及沥青焦油聚氨酯可以提高抗老化性能。膨胀焦油聚氨酯可代替膨胀橡皮 ,造价低 ,适用已建成的工程伸缩缝止水处理。水溶性环氧树脂适于有水面施工 ,克服了环氧树脂的缺陷 ,应用范围更加广泛。环氧聚氨酯具有刚中有柔的性能 ,适于特殊工程的处理
Tar urethane is poisonous, is afraid of water, and has poor anti-aging ability. It has no mocca curing agent and can reduce toxicity and can be applied on wet surfaces. Color and pitch tar polyurethanes can improve anti-aging properties. The expanded tar polyurethane can replace the expansion rubber, and the cost is low. It can be applied to the existing engineering expansion joints to stop water treatment. Water-soluble epoxy resin is suitable for water surface construction, overcomes the defects of epoxy resin and has a wider range of applications. Epoxy urethanes have soft and soft properties suitable for special engineering processes
