A typical coal-tar enamel coating consists of liquid primers (adhesives), coal tar enamels, inner-wraps, outer-wraps, and finish coats (kraft paper, whitewash and/or water-emulsion latex paint). Liquid primers (adhesives) produce a bond between the metal and coal tar enamel. They are applied by …

Coal tar pitch was a by-product of processing coal to make coke, which in turn was used in making carbon steel and electrodes for the aluminum industry. Asphalt, a by-product of processing petroleum to make gasoline, fuel oil, and various hydrocarbon polymers, was also popular. Roofing systems originally consisted of alternate layers of hot ...

The most common non-coal tar sealcoat is petroleum asphalt-emulsion (CAS number ). Good asphalt sealcoat emulsions are affordable, provide a black appearance for one to two, and can provide ongoing protection for two to four years if properly applied. They can be used in locations that ban coal tar.

This gives Asphalt Emulsion an advantage because it has a longer life than Coal Tar. Another reason that Asphalt Emulsion has a better durability is simply because it is made from the same asphalt base material. Asphalt has the tendency to expand and contract based on weather and temperature. The Coal Tar, while hard, does not expand or contract.

Coal tar is a byproduct of the coking, liquefaction or gasification of coal. Coal-tar pitch is the residue that remains after the distillation of coal tar, that is, the thick black liquid remaining after various oils are removed from coal tar for use in the manufacture of industrial and consumer products. Coal-tar pitch is separated, or "refined", into 12 grades of viscosity.
