Abstract

The present invention provides an anti-corrosion composition comprising an inorganic ion-exchanger and a waterborne resin, wherein a substrate exposed to a halide-containing environment and having the anti-corrosion composition applied thereto has a reduced level of corrosion compared to the substrate exposed to the halide-containing environment without the anti-corrosion composition being applied. The inventive waterborne anti-corrosion composition may find use on substrates such as automotive vehicles, bridges, cranes, superstructures, offshore oil & gas rigs, pipes, tanks, ships, barges, boats, aircraft, concrete, and masonry that are exposed to halide-containing environments.
