Price is driven by binder content, base bitumen grade, emulsifier package cost, and any modifiers like polymers, latex, or rubber. Higher binder content generally raises cost but can reduce applied volume needs if performance targets are met. Specialty additives for adhesion, storage stability, or waterproofing performance increase raw material cost and may increase production complexity, which adds OPEX. Water quality and pH control chemistry also add cost in some systems. Finally, formulation influences shelf life and rejection risk, which affects the supplier margin and the delivered price, especially for long distance logistics.
