Petra Oil’s RS-2 is a high-performance rapid setting cationic bitumen emulsion, specifically formulated for demanding surface treatments and road maintenance operations that require fast curing and strong bonding. RS-2 stands for Rapid Setting – Grade 2, and compared to RS-1, it contains a higher bitumen content, making it particularly well-suited for surface dressing works where durability and quick trafficability are critical.

Engineered using a carefully selected blend of cationic emulsifiers and premium-grade bitumen, RS-2 offers fast breaking and setting even in cool or humid conditions. It adheres exceptionally well to aggregates and pavement surfaces, ensuring a strong, uniform coating that extends the life of the road. Its quick setting time allows for rapid completion of roadworks and minimizes traffic disruptions—ideal for busy highways, urban roads, and rural surface treatments.
