Climate change poses new challenges in protecting steel infrastructure from corrosion, particularly in
coastal regions experiencing record temperatures, humidity levels and rainfall. These extreme
environmental forces, in the presence of salts and pollution, can accelerate corrosion of critical steel
structures such as bridges, electrical utilities and telecommunications, increasing the likelihood of
catastrophic failure. Conventional anti-corrosion coating systems are vulnerable to degradation under
these same extreme environmental conditions and require costly maintenance programs, multiple timeconsuming re-coats and in severe cases of neglect, early failure. This paper explores a novel multilayer coating solution consisting of a topcoat formulated with an aqueous polyvinylidene fluoride (PVDF)-acrylic dispersion that has demonstrated decades of exceptional coastal durability in architectural applications. Combined with an innovative cathodic primer layer and mid-coat, this system demonstrates benefits in ultraviolet radiation durability and corrosion resistance when compared to conventional anti-corrosion coating systems.
