Coal-Tar Emulsion Coating
This specification covers a coal-tar emulsion coating to be used as a protective weather coat for hot- or cold-applied bituminous coatings on steel structures. It may also be used over suitable primers as a protective coating for aboveground steel structures subjected to atmospheric exposure and the deleterious effects of oxidation and ultraviolet radiation. It is suitable for use on parts or structures exposed in Environmental Zone 1B (exterior, normally dry). It can also be used in heavy industrial environments such as Zones 3A (chemical exposure acidic), 3B (chemical exposure neutral), and 3C (chemical exposure alkaline) where color is not a prime consideration.
