If you’ve ever wondered what asphalt sealcoating is, look no further. The Youtube video “Asphalt Sealcoating 101 What is Driveway Sealer?” has all the information so you can understand why this process is necessary. Let’s find out more!
Asphalt sealcoating is made from a base, which is an emulsion blend. There are two different sealers in the industry: asphalt-based and coal tar-based.
The difference between them is that asphalt is extracted from the petroleum-refining process, whereas coal tar is extracted from the process of refining steel. The latter product looks pretty similar to asphalt, as it’s a sort of resin, gray substance.
The issue is that coal tar has been proven to have polycyclic aromatic hydrocarbons, which are carcinogens. Meanwhile, asphalt-based sealers don’t have that, so they’re automatically the better option. Additionally, asphalt is a reusable material because liquid asphalt is taken from the same product used in driveways and such.
The process consists of heating the asphalt at temperatures over 300 degrees Celsius and extracting the liquid that comes out. Afterward, it’s mixed with emulsifiers and water to create a stable substance for sealcoating. You can watch the rest of the video for more details about asphalt sealcoating.
