COATING COMPOSITIONS

摘要

. D15897 - JPW COATING COMPOSITIONS Multi-layered coating compositions which comprise one or more inner coating layers which are admixtures of polymers formed from thermosetting polymeric materials and reinforcing filler materials and an outer coating layer which is an admixture of a fluoroelastomeric material and a reinforcing filler material are useful in preventing the corrosion and/or deterioration of surfaces which are in contact with corrosive substances such as strong acids, particularly, sulfuric acid. Such coating compositions are especially useful for preventing corrosion of the surfaces of the chimney liners, flue ducts and scrubbers which are present in many power plants and smelters.
