1、SWD城市立交桥专用防腐防水涂料SWD urban overpass special anti-corrosion waterproof coating产品说明 我国改革开放三十年来，城市立交桥如雨后春笋般大量涌现，坐落在各个美丽的城市。立交桥的建设为改善城市交通，方便市民出行立下了汗马功劳。但由于立交桥防腐防水处理不好，近几年立交桥突然断裂、倒塌的事故频频发生，给国家财产和人民生命造成了重大损失和伤害，社会影响极坏。因此，立交桥的安全维护成了城市管理者头等重要的研究课题。美国SWD聚氨酯公司早在上世纪80年代，就根据城市交通建设发展的需要，研发生产了用于立交桥防护的防腐防水涂料。该材料现已在
