Anticorrosion Waterproof One Component Polyurea Protective Coating Specifically For Urban Overpass
The coating's primary membrane former is high performance one component polyurea resin prepolymer, it cures by the reaction between the coating and moisture in the air. Hydrogen bond existing among molecular bonds of the coating brings huge cohesion among molecule. The existence of hydrogen bond and urea bond determines a good performance of anti-corrosion and waterproof. Under strict application system, the service life of coating could be 15 years above.
Over the past three decades, since open-up policy, a number of urban overpasses have been built, located in differedt cities of China. Overpass projects contributed a lot to develop the urban traffic and benefit the civillians. Owing to a failure of anticorrosion and waterproof treatment, recent years some overpasses broke and collapsed suddenly, caused a great loss and harm to national properties and people's lives,which brought bad social influence. Hence the safety and maintenance of overpasses became an important research topic for goverment. Our compant's polyurea coating specially developed for overpass meets the needs of urban transportation comstruction and is widely used all over the world.
