Anionic Emulsion

What is Anionic Emulsion Bitumen?


The term anionic is derived from the migration of particles of bitumen under an electric field. The droplets migrate toward the anode (positive electrode), and hence the emulsion is called an anionic emulsion, there are billions and billions of bitumen droplets with emulsifying agent at the water bitumen interface. The tail portion of the emulsifying agent aligns itself in the bitumen while the positive portion of the head floats around in the water leaving the rest of the head negatively charged and at the surface of the droplet. This imparts a negative charge to all the droplets. Since negatives repel each other, all the droplets repel each other and remain as distinct bitumen drops in suspension. A typical anionic emulsifying agent is shown below along with a diagram showing the orientation of the agent at the bitumen-water interface and the negative charge imparted to each drop.


  • • 220, 230, 240(Liter) new steel drum.
    • Bulk; Transit cargo and Flexi Tank.
    • IBC 1000(Liter) material new.
    • Gallon 20 Liters.

Uses of Anionic Emulsion

• Processing: The emulsion is brown in steady state.
• Level statue: Should be clean/dry/without dust.
• Stir well before use.
• Apply the material using a grass brush, a paintbrush, a roller or a paint sprayer gun.
• If you install a fiberglass mesh reinforcement between the layers, you can apply the WATER-BASED PRIMER undiluted.
• It is affected by petroleum products. Tools should be cleaned with water immediately after use, before the emulsion dries. Once it has dried, you need to use oil.
