Cationic Emulsion

What is Cationic Emulsion Bitumen?


The term cationic is derived from the migration of particles of bitumen under an electric field also. The droplets migrate toward the cathode (negative electrode), and hence the emulsion is called cationic. The cationic emulsifying agent functions similarly to the anionic; the negative portion of the head floats around in the water leaving a positively charged head. This imparts a positive charge to all the droplets. Since positives repel each other, all the droplets repel each other and remain as distinct bitumen drops in suspension. A typical cationic emulsifying agent is shown below along with a diagram showing the orientation of the agent at the bitumen-water interface and the positive 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 Cationic 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.
