      Frequently Asked Questions.

      K1-40 is a cationic slow-setting bitumen emulsion formulated for slurry seal and surface treatment applications, offering good workability and strong aggregate bonding.

      K-10 bitumen is a medium-setting cationic bitumen emulsion where fine bitumen particles are dispersed in water with a positive electrical charge. It is designed for strong adhesion to mineral aggregates, especially in road construction and surface treatments.

      2. Where is K-10 bitumen commonly used?

      K-10 bitumen is widely used in tack coats, prime coats, surface dressing, patch repairs, and maintenance works. Its cationic nature makes it especially suitable for aggregates with a negative surface charge.

      K-10 offers excellent adhesion, uniform coating, quick breaking, and ease of application. It can be applied at ambient temperatures, reducing energy consumption and improving site safety.

      Yes. K-10 cationic bitumen emulsion can be applied on slightly damp surfaces, making it ideal for regions with variable weather conditions. However, free-standing water should be avoided for best performance.

      K-10 bitumen should be stored in clean tanks at temperatures between 5°C and 50°C, with gentle agitation if stored for extended periods. It should be protected from freezing and direct contamination.
