The protective coating systems are intended for use on bridges, similar structural steel, and otherferrous metal surfaces, both new and existing, prepared by abrasive blast cleaning, which are subject to corrosive atmospheric environments, such as marine, industrial, deicing chemicals, and high humidity.

The values stated in SI units are to be regarded as the standard.
