Coal Tar for paving, fuel
1. Description
Coal tar is a kind of organic compound (mainly aromatic hydrocarbon), and it is an important by-product in the coal processing industry. Coal tar is the basic raw material of chemical products like synthetic plastic, synthetic fiber, pesticide, dyestuff and medicine as well as basic raw material in such sectors as metallurgy, construction, textile, paper making and traffic.
Coal tar is a brown or black liquid of extremely high viscosity. Coal tars are complex and variable mixtures of phenols, polycyclic aromatic hydrocarbons (PAHs), and heterocyclic compounds, about 200 substances in all.
2. Properties
Coal tar is a kind of black or black brown sticky liquid got during the process of coal coking .Coal tar has special distinctive odor. Its relative density is 1.18~1.23 and the open flash point is at 200°C, and it is slightly dissolvable in water and soluble in organic solvent like benzene, alcohol, ethyl ether, chloroform, acetone etc.. Its fume and air can become explosion mixture, meanwhile, if it meets open fire, the heat, its container may have the danger to craze and explode. Therefore, we should be careful when we carry them.

4 Application
When it comes to building projects, this coal by-product can be used for roofing jobs, coal tarprovides a nice sealant underneath shingles. It is also an ideal way to seal pitches in the roof, providing a water tight seal for all angles of the roof line. In addition to the sealing agents, coaltar also works as an insulating agent, working with the wall insulation to help maintain a comfortable temperature inside the building, regardless of the outside weather. There are also a number of exterior paints that utilize coal tar in their finished product. The substance provides an excellent sealed surface once it dries in place; the paint is much less likely to chip and peel over the years with a small amount of coal tar included in the mix.
