RoadStar Slow Setting Emulsion are the most stable of emulsions, and generally can be diluted with water and mixed with mineral fillers and aggregates for all uses.
RoadStar Slow Setting Emulsions binds the loose aggregates and is designed for use as a prime coat (when it is diluted) tack coat, base stabilization, fog sealing, slurry seal, dust control and specialty applications. Slow setting emulsion is further sub divided into SS –1 and SS –2 types.
