  1. www.stpltd.com ShaliMulsion A/C Cold-applied Anionic/Cationic Bituminous Emulsions

  2. www.stpltd.com ShaliMulsion (A liquid within a liquid) An emulsion is a dispersion of small droplets of one liquid in another liquid ShaliMulsion is a dispersion of bitumen droplets in water, chemically stabilized using emulsifiers and other additives

  3. www.stpltd.com BLENDING IT RIGHT Bitumen particles get dispersed in water to form an emulsion with chemicals aiding in it’s stabilization Hot Bitumen, emulsifiers & additives are subjected to high shear force in a colloid mill ShaliMulsion

  4. www.stpltd.com S h a l i M u l s i o n PROCESS DYNAMICS Bitumen Solvent HEAT Batch Tank Emulsifier + Additives Colloid Mill HEAT Emulsifier Soln In Water

  5. www.stpltd.com ShaliMulsion: A (Anionic) Emulsifier Polar Heat O CH2 CH2 CH2 CH2 C Na + _ O CH2 CH2 CH2 CH2 CH2 Non-Polar Tail • Emulsifier derived from reaction of fatty acid with a base such as caustic soda(Na OH) or caustic potash(KOH) • Imparts a negative charge to the bitumen droplet • Effective in coating positively charged aggregates - - - - - Bitumen Droplet - - - - - - - -

  6. www.stpltd.com ShaliMulsion: C(Cationic) Emulsifier Polar Heat H CH2 CH2 CH2 CH2 H N + Cl - CH2 CH2 CH2 CH2 CH2 H Non-Polar Tail • Emulsifier derived from reaction of various amines (depending on use) with an acid (HCl) • Imparts a positive charge to the bitumen droplet • Effective in coating nearly all but the most electropositive aggregates + + + + + Bitumen Droplet + + + + + + + +

  7. www.stpltd.com ShaliMulsion : Setting Process Evaporation facilitates close approach and adhesion of droplets Flocculation Stable emulsion. Charge on the bitumen droplets prevents them from coming close Further evaporation & drainage breaks the emulsifier film: droplets coalesce to form large particles until a film is formed binding the aggregates Coalescence

  8. www.stpltd.com BREAKING Bitumen Particles Coalesce & Bind the Mineral Aggregates EMULSION + MINERAL AGGREGATES Evaporation PAVEMENT Drainage Breaking of ShaliMulsion Occurs by Evaporation & Drainage Fully Cured Curing

  9. www.stpltd.com ShaliMulsion A Works best in warm&dry conditions. Suitable for soil stabilization & patching road surfaces Effective in coating positively charged aggregates such as limestone & marble

  10. www.stpltd.com ShaliMulsion C Highly versatile .Ability to adsorb on to a wide range of mineral aggregates Results in better adhesion to mineral aggregates and is effective for use in all weather conditions

  11. www.stpltd.com Tailor –made as per your need

  12. www.stpltd.com ShaliMulsion RS Used primarily for tack coat and spay applications such as aggregate seals, surface treatments asphalt penetration macadam & grouting Designed to react quickly with aggregates and revert from the emulsion state to the bitumen

  13. www.stpltd.com ShaliMulsion MS Does not break immediately in contact with the aggregates & remains workable for a few minutes Designed for mixing with coarse aggregates and are ideal in premix Has high viscosity to prevent run-off. Ideal for surface dressing work

  14. www.stpltd.com Very low viscosity that can be further reduced by adding water ShaliMulsion SS Designed for maximum mixing stability Used with very high fine dense-grade aggregates Blends can be diluted (upto 50%) for prior coats, fog seals, slurry surfacing &dust palliatives

  15. www.stpltd.com “DISPERSE” YOUR WORRIES….. Environment Friendly Cold Applied Eliminates Fire Hazard ShaliMulsion All-Weather Applicability (Rain / Low Temperature) Pollution Free & Non-Toxic Fluidity Ensures Complete Penetration of Aggregate Mass Can Provide Quick traffic Restoration

  16. www.stpltd.com IMPORTANT ! Water Imparts Fluidity Which Aids in Bitumen Penetration Prior to Application Surface should be cleaned off loose Aggregates. Dust to be Dampened With Clean Water Brushing is not Recommended Until ShaliMulsion Turns Black Disallow Foot Traffic Till ShaliMulsion Breaks to Form a Black Surface Never Mix Two Types of ShaliMulsion as this will cause Coagulation

  17. Trust only ShaliMulsion www.stpltd.com Be SURE of a CURE That ENDURES…
