What is the Difference Between Coal Tar and Asphalt?Ĭoal tar and asphalt are important hydrocarbon materials. The applications of asphalt are in the construction of highways, airport runways, car parks, tennis courts, roofing, dam, pipe coating, etc. ![]() Additionally, this substance is important in producing some waterproofing products, such as sealing flat roofs. In this application, this substance is the glue or binder, which can be mixed with aggregates in creating asphalt concrete. The major application of asphalt is in road construction. The synthetic form of asphalt can be known as “refined bitumen.” This substance is formed from the fractional distillation of crude oil at high temperatures. The naturally occurring form of asphalt is often known as “crude bitumen.” Furthermore, this substance has a viscosity that is similar to the viscosity of cold molasses. Besides the occurrence in natural deposits, asphalt forms as a byproduct of refining processes. We can find it in the semi-solid state as well. What is Asphalt?Īsphalt (also known as bitumen) is a naturally occurring dark, thick liquid that is highly viscous and sticky. ![]() The common side effects include skin irritation, sun sensitivity, allergic reactions, and discoloration of the skin. However, there are some side effects of using coal tar in different products. In industrial applications, it is used in boilers for heating due to the flammable nature of coal tar. In construction sites, coal tar is known as a sealing agent it is mostly used by incorporating into parking-lot seal coat products. Moreover, coal tar is important in the field of construction and other industries. In medicinal applications, coal tar is used in one of two forms: as crude coal tar or as coal tar solution. It is used as a treatment for dandruff and psoriasis. That means we can apply it on skin or hair. Generally, coal tar is an important ingredient in some shampoos, soaps, and ointments. According to WHO listings, coal tar is among the safest and most effective medicines. This substance was produced in 1665 as a component important in the field of medicine. There are two major trade names for coal tar: Balnetar and Cutar. ![]() In industrial applications, coal tar is important because of its flammable nature and sealing ability. In addition, coal tar is important in the field of medicine due to its significant properties such as antifungal, anti-inflammatory, anti-itch, and antiparasitic properties. It is a liquid having both medical and industrial uses. Summary – Coal Tar vs Asphalt What is Coal Tar?Ĭoal tar can be described as a dark, thick liquid that forms as a byproduct of the production of coke from coal. These are collectively known as bituminous materials. Both these are dark-colored substances and are hydrocarbon substances. 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.Ĭoal tar and asphalt are important substances in construction applications and some other applications.
