EM-620 rapid setting cationic bitumen emulsifier is able to be widely applied for production heavy-duty bitumen and SBS modified bitumen, which is used in chip seal and modified tack coat with high performance to price ratio.

EM-620 RS emulsifier is light yellow paste or liquid at ordinary temperature. It should be accurately measured, and then completely dissolved in acidic water above 50 oC slowly. The soap solution should be adjusted to the required PH value and temperature for tack coat or chip seal SBS emulsion application.
