      Frequently Asked Questions.

      CSS-1 is a cationic slow-setting bitumen emulsion that provides extended mixing time before breaking, making it suitable for applications requiring thorough aggregate coating.

      2. Where is CSS-1 commonly used?

      It is widely used in:

      • Slurry seals
      • Micro-surfacing
      • Cold mix asphalt
      • Soil and aggregate stabilization

      CSS-1 breaks slowly, allowing sufficient time for mixing, transporting, and placing the mix without premature setting.

      • Excellent workability
      • Uniform aggregate coating
      • Strong adhesion to aggregates
      • Suitable for cold application and eco-friendly operations

      CSS-1 should be stored in clean, temperature-controlled tanks, kept above 5°C, and protected from contamination to maintain emulsion stability.
