Key words are concrete structures, dams, geomembranes, hydraulic structures, leakage, repair, and underwater repair. The U.S. Army Corps of Engineers has used solution vinyl paints for the corrosion protection of hydraulic structures on inland waterways for many years. To comply with existing and anticipated pollution regulations, it is necessary to evaluate potential coatings to replace those being currently used. F151, Type IV topcoat. This report includes laboratory and field test results.
Key words are coatings, hydraulic structures, and volatile organic compound.
The U.S. Army Corps of Engineers relies heavily on the use of vinyl paints for coating hydraulic structures. Though the systems have performed well in many environments, their high solvent content has made their use illegal under some local air-pollution control legislation. High-solids epoxies available in the current guide specification will comply with the regulations and may provide acceptable performance in some applications. Overall, this study showed that the coatings are tolerant of a wide range of applications and curing variables frequently encountered under field conditions. The results of this work do not indicate a need for revising CWGS-09940 at this time.
