"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.

• Flash Point   : Not Flammable.
• Viscosity   : 4000 cps.
• pH : 2 - 4
• Shelf Life   : 1 Year from the date of production in sealed containers.
• Colour   : Yellowish white turbid liquid.
• Odor : Almost odorless.
• Compatibility: Most grades of Cationic Bitumen Emulsions.

Bitumen Emulsions have a lot of variation in their viscosities depending on the type of bitumen used, type of emulsifier, dose of acid, particle size distribution etc. Most of the time an external viscosity improving agent is required to meet specifications and coating properties.
Solid thickeners are the powders obtained from complex natural products modified by chemical cleavage and re-formation to provide stability in low pH medium. "BeGel" is a modified polygalactomanan type low dose product which is compatible with most grades of Bitumen Emulsion and emulsifiers. This product is added into hot water before formation of Bitumen Emulsion to obtain high viscosity.

Physical Properties :Fine Power in light yellow colour with chararcteristic Odour, substantially non-hazardous but irritant on prolong contact. Dispersible in water, giving thick colloidal dispersion. Shows mild alkaline pH in water.

Chemical Properties :

• Chemical Name   : Modified Galactomannan
• Water Content : Max. 15%
• Flash Point   : Not Flammable.
• Viscosity   : 3000 cps (0.5% aqueous solution)
• pH : 8 - 9 (0.5% aqueous solution)
• Shelf Life   : 1 Year from the date of production in sealed bags.
• Colour   : Yellow Fine Powder.
• Odor : Characteristic.
• Compatibility: Most grades of Cationic Bitumen Emulsions.

Typical Dose & Method of Addition :BeGel should be used between 0.1% to 0.5% w/w of Water. BeGel should be added to hot water (Temperature between 50 and 80 Degree centigrade) in smaller quantities using a dispersing device like sieving through 0.6 mm sieve with constant stirring to avoid lumping. Stirring should be continued for 15 minutes and then the liquid can be used normally in place of water. If lumping occurs, the liquid can be filtered through 0.6 mm sieve to avoid agglomeration.
