产品特点
1、优异的拉伸强度和耐撕裂性能；
2、湿铺施工时，对于基层要求不高，不需要底涂，尤其适用于雨季较长、潮湿环境下的防水施工；
3、卷材具有良好的“自愈”功能，可以自行修复基层发生的微小裂纹；
4、施工过程无需动火，环保安全；
5、添加专用改性剂，在湿铺卷材施工时，改性沥青胶与水泥胶浆产生物理卯榫作用，同时可在水泥发生水化热的过程中产生化学交联，从而形成“皮肤式满粘”的效果。
1. Good performance of tensile strength and tear resistance.
2. The wet-installation do not need the primer, especially is suitable for engineering with wet substratum because of wet season.
3. The product self-healing function can availably repair tiny cracking of the substratum.
4. Safety and environmentally friendly, the application of self-adhesive waterproof materials is simple and convenient, which can avoid open-flame working.
5. The modified bitumen using polymer modifier can produce physical mortise and tenon effect with cement grout and thermal reaction during cement solidification process, which is adhered to substratum fully and tightly.
