Anionic Bitumen Emulsion HFMS-2

Anionic emulsions have several grades depending on its breaking characteristics. This breaking process is predominantly dependent on the evaporation rate of the water in the emulsion. The more higher the water evaporation rate, the more rapid the setting is. Different setting rate is crucial as different application requires different setting rates. Rapid setting emulsions are usually used in surface dressing while slow or medium setting emulsions are usually used for mixtures. 

Anionic emulsions carries negative charge, compared to cationic emulsions which carries positive charge. When an anionic emulsion is mixed with a cationic emulsion, a strong bond develop and changing the substance to a solid. This is unfavorable as it cannot be applied to substrates.

Our HFMS-2 grade anionic bitumen emulsion is a rapid setting, anionic, bitumen emulsion. They are further characterized by their ability to remain stable on storage although produced with equipment that generates a wide range of shearing forces. Such characteristics are imparted to the asphalt emulsions through the use of emulsion conditioner compositions comprising a partially desulfonated lugonosulfonate, preferably an anionic or non-ionic emulsifying agent and, optionally, a thickener.
