The concept of a barrier coating is applicable to any structure that requires repetitive paint removal. In principle, the coating is applied between a corrosion protective primer and protective topcoat for the purpose of encapsulating the corrosion resistant properties of the primer/surface treatment and allowing for a selective removal of the topcoat using acceptable mechanical coatings removal techniques. The 5-part coating system can be used on any type of structure that requires routine maintenance or repainting to preserve the integrity and/or appearance of the structure. Benefits associated with the concept of barrier coating include a significant reduction in the costs and manpower required to remove and reapply primer and topcoat systems from air- and land-based transportation vehicles, storage buildings, bridges and miscellaneous other structural applications. A second important benefit includes a reduction and/or elimination of the environmental hazards associated with (1) the treatment and disposal of primer and surface treatment residues (chromates, etc.), and (2) the release of toxic airborne pollutants during the precleaning, paint stripping, and painting operations conducted on large structures, thus limiting the exposure of workers.
