Iniciodifference between coal tar and asphalt seal
Asphalt takes less time to settle, while coal tar takes more time. Is coal tar the same as asphalt? Coal tar is obtained from the destructive distillation of organic substances such as coal, wood, or other bituminous materials. Asphalt is found in natural deposits or obtained as a residue in refining of petroleum.
Asphalt sealer is a more environmentally friendly option as it produces less VOC. Acrylic Polymer Sealer: A synthetic type of sealer provides the same protections against organic and non-organic materials as coal tar sealer but is often less cost-effective than the other sealer types.
Coal tar is the by-product obtained during the production of coal gas. It is used for preserving timber, laying macadam roads etc. The process consists of coal heated in closed iron vessels and the evaporated gases are collected in tubes. These tubes are circulated with cooling water.
The key difference between coal tar and asphalt is that coal tar is a dark-colored substance that is collected from the destructive distillation of organic substances, whereas asphalt is obtained as a residue from the distillation of petroleum or from natural deposits. The following table summarizes the difference between coal tar and asphalt.
Coal tar is mostly used to cover surfaces because it has high resistance to corrosive materials. Also, tar is used to manufacture soap, shampoo, and fuel.

Coal tar pitch is one of the main products of coal tar processing. It is the residue after distillation of coal tar. Petroleum asphalt is a product of crude oil processing. It is a viscous liquid, semi-solid or solid at room temperature. It mainly contains hydrocarbons and non hydrocarbon derivatives soluble in trichloroethylene.
While sealcoating protects and finishes existing asphalt, sealcoating is not intended to fill large cracks or holes in the pavement. Sealcoating protects the asphalt from UV rays, oils, fluids, salts, and other contaminants that otherwise lessen the overall life of the pavement. There is no point in just sealing over broken pavement, although ...
The difference between acrylic polymer sealer and coal tar is the amount of VOC that each emits. Acrylic polymer does not emit as much as VOC levels as that of coal tar.
