??????? ?spray elastomer seawater desalination caisson special polyurea anticorrosion wear resistance coating

???????????????????????

?Descriptions??? ???????????Due to the shortage of water resource, seawater desalination procedure has gained more and more attention in recent years, and relative projects of that have also been increasing each year. As a perfect combination of? new technique, new material and new procedure, Polyurea Spray Elastomer Anticorrosion Waterproof Coating, with its high physical performance and super anticorrosion function is closely concerned in the anticorrosion and waterproof field and is widely applied to significant programs. According to the using environment of large caisson in seawater desalination, SWD Urethane Co., USA developed Polyurea anticorrosion coating with its excellent corrosion resistance to seawater, and cathodic disbondment strength, has been widely applied among many projects in Australia and worldwide.-???????????????????????????????????????????????????????????????????????????????????????????????????????? ?????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????
