Emulsion Bitumen

Emulsion bitumen is a type of asphalt binder produced by suspending bitumen droplets in water, using an emulsifying agent. It’s classified based on the type of emulsifying agent used. Common types of emulsion bitumen include cationic, anionic, and non-ionic emulsions, used in various applications, such as surface treatments, prime coats, and tack coats. Emulsion bitumen offers advantages such as lower application temperatures, better adhesion, reduced VOCs emission and ease of handling compared to other types. However, it may require additional curing time and is not suitable for high-traffic areas.

Please don't hesitate to ask if you have any questions whatsoever.
