What differentiates SS-1 bitumen emulsion from medium and rapid setting grades?

SS-1 is a slow setting emulsion designed to remain stable longer during mixing and handling, making it suitable for slurry type applications, cold mixes, and situations requiring more work time. Medium and rapid setting grades are designed to break faster on contact with aggregate or surface, supporting quick traffic return and stronger early bond in surface dressing or tack applications. SS-1 typically has emulsifier chemistry and pH control optimized to delay break, plus a viscosity profile suited to mixing rather than instantaneous spray break.
