Thickeners are natural or synthetic substances which are used to increase the viscosity of a liquid system. A thickener can be liquid or a solid depending on the source of raw material and intended applications.To increase the viscosity of bitumen emulsions, mostly the residual bitumen is increased which in turn increases the cost to a very high level. Few emulsifiers claim to increase the viscosity and storage stability of Cationic Bitumen Emulsion but a fine balance of dose is required as low dose does not increase viscosity and a slight higher dose develops lumps in final emulsion causing it to fail in sieve test. Also prolonged storage of Bitumen Emulsion in open under hot and cold conditions cause the Bitumen Emulsions to cream (separation of water and formation of hard bitumen layer) and site dilution of Bitumen Emulsions by road contractors causes the breaking of emulsions which are serious issues for emulsion manufacturers.

Cationic Bitumen Emulsions contains cationic emulsifiers which are stabilized using strong acids like HCl under very low pH. Most of the natural and synthetic thickeners are not stable on this pH and disintegrate within hours of addition causing sharp fall in viscosity.

"PSEM-THX" is liquid thickener specially designed to remain stable in low pH conditions and can be conveniently blended with any Cationic Bitumen Emulsion. Unlike solid thickeners which require blending with soap water before making Bitumen Emulsion, "PSEM-THX" can be easily mixed after making bitumen emulsions and provide excellent viscosity increase with low dose requirement.

"PSEM-THX" in addition to increased viscosity, also make Bitumen Emulsions better stable on storage. A Cationic Bitumen Emulsion stabilized with "PSEM-THX" remains fully usable for minimum 1 year even when stored in open area during summers and winters. "PSEM-THX" also prevent breaking of Bitumen Emulsion on addition of water (even in high volumes).

Physical properties:
Turbid white thick liquid at room temperature with characteristic odour,. Miscible with water and Cationic Bitumen Emulsions of all grades. Ready to use product for post-addition after formation and cooling of Bitumen Emulsion. Improves viscosity, storage stability and the water dilution properties of bitumen emulsion. Stable even on very low pH.

Storage and handling :
PSEM-THX can be stored in MS or HDPE Barrels. The product is water based and very thick. Product can be diluted in correct proportion with water and used conveniently.
