The paper briefly describes the influence of marine environment on the durability of structures, introduces the technological advantage of pure polyurea technology, the application of Hongkong-Zhuhai-Macao bridge and Qingdao Bay Bridge. The adhesion performance and the surface appearance and structural morphology of pure polyurea materials after the salt-fog and UV/ salt-fog alternating were investigated through tracking adhesion test, scanning electron microscope(SEM) and Fourier transform infrared spectroscopy(FTIR). The result shows that, pure polyurea material has excellent adhesive ability and strong resistance to salt-fog and UV/ saltfog alternating, and it has excellent long-term protective ability. Pure polyurea technology can undertake the hundred mission of protection to bay bridge.
