      K1-70 is primarily used for tack coats, surface dressing, and patch repair works. Its cationic nature allows it to bond effectively with aggregates, especially in road construction and maintenance projects.

      2. What does “cationic” mean in K1-70 bitumen emulsion?

      “Cationic” means the bitumen particles carry a positive charge, which helps them adhere strongly to negatively charged aggregates like granite and basalt, ensuring faster breaking and better bonding.

      Yes. One of the advantages of K1-70 cationic emulsion is that it can be applied on slightly damp surfaces, making it suitable for use in humid or light-rain conditions where hot bitumen is not ideal.

      K1-70 (cationic) breaks faster and provides stronger adhesion compared to anionic emulsions, making it more suitable for modern road construction where quick setting and durability are required.
