One of the method for modifying bitumen is emulsification with water which enhance bitumen properties incredibly. Another advantages of modification is that it can be applied cold (80°C). Emulsion bituminous asphalt consist of two immiscible liquids which are stabilized by emulsifier. They usually used for tack coats, hot-mixed asphalt, prime coats, chip seal. Firstly Anionic emulsion were developed and because cationic emulsion has more adhesion properties they are more favored especially in tack coating. The type (chemistry) of the emulsifying agent used, determines the designation. During application, the water in a bitumen emulsion is either lost by evaporation, or it may separate from the bitumen because of the chemical nature of the surface to which the emulsion is applied. This process is referred to as breaking.

Depending on the type of emulsifier the bitumen particles can be both positive and negative. Emulsions in which the bitumen droplets are negatively charged are called anionic emulsions. Emulsions in which the particles are positively charged are called cationic emulsions.

Anionic emulsion is obtained by electric field. In anionic emulsion the droplets migrate from anode. Anionic bitumen emulsion HFMS-1 is a medium setting , anionic type of bitumen. The particle size of the emulsion is 0.1 to 5 micron. HFMS-1 is a safe product and is easy to use, because of high flash point and low solvent content.

The main applications of Anionic bitumen emulsion HFMS-1 are waterproofing,  building application,  Coatings Industry ,highway construction, tack coat, surfacing and maintenance.
