Coatings for aboveground steel in coal-fired plants

The environment around a coal-fired plant is such that conventional oil-bas ed paints do not provide adequate protection. However, zinc-rich epoxy prim ers with a high-build epoxy topcoat have performed satisfactorily. Successf ul coating performance can be achieved after steel erection, but a better a pproach would be to apply the primer and topcoat before shipping a structur e to the job site.
