During the early and mid-20th century, when town gas was produced, coal tar was a readily available byproduct and extensively used as the binder for road aggregates.
Petroleum-based sealer falls between refined tar and asphalt. There are concerns about pavement sealer polluting the environment after it is abraded from the surface of the pavement.

It is made from layers of ground wood pulp fibers and asbestos fibres compressed with and bound by a water resistant adhesive then impregnated with liquefied coal tar pitch .
Depending on the FBE coating system, full cure can be achieved in less than one minute to few minutes in case of long cure FBE's, which are used for internal pipe coating applications. Rebars are coated in a similar manner as coating application, on the exterior of pipes. For FBE coating application on the interior of pipe surface, a lance is used.
