RUST STABILIZING SURFACE TREATMENT FOR ATMOSPHERIC CORROSION-RESISTANT STEEL (RS-COAT)

It is well known that atmospheric corrosion resistant steel has a beautiful appearance which it does reach over a long period of exposure. During initial exposure, however, the rust forming sometimes pollutes surrounding structures. Rs-coat has been developed for use in rust stabilizing surface treatment. It uses a special urethane resin-based coating that contains various pigments effective in rust stabilization. Those pigments lower the ph value of the steel surface, promote the dissolution of steel under a urethane resin coating, and thus contribute to the early stabilization of rust. This special coating is applied in one operation to the surface of an atmospheric corrosion resistant steel descaled by blasting or pickling. Since the urethane resin is permeable to gas and water, it supplies adequate quantities of water and oxygen to the steel surface until stable rust is formed on the surface of the steel. This almost completely prevents the outflow of rust-bearing yellow water and the scattering of rust. Rs-coat has been used successfully in bridges. (TRRL)
