    What is HFMS-1 Bitumen Emulsion?

    HFMS-1 (High Float Medium Setting – Grade 1) is an anionic bitumen emulsion designed to provide a gel-like, high-float residue that creates a thicker and more flexible bitumen film on aggregates.

    Key characteristics:

    • High float property → forms a gel structure for thicker coating
    • Medium setting behavior → allows mixing before curing
    • Negative charge (anionic) → works best with calcareous aggregates
    • Enhanced durability → resists cracking, peeling, and water damage

    The “HF” designation indicates a special emulsifier system that produces a high-float residue, improving resistance to oxidation and environmental stress.

    Unlike standard MS emulsions:

    • HFMS-1 creates a stronger, more elastic film
    • Performs better under temperature variation and traffic stress
    • Offers longer-lasting surface performance

    Applications of HFMS-1 Bitumen Emulsion

    Chip Seal

    Provides superior aggregate bonding with enhanced durability.
