Petra Oil’s QS-1h is a premium-grade anionic quick setting bitumen emulsion specially developed for road construction applications such as surface dressing, patching, and maintenance where fast setting time and strong adhesion are essential. QS-1h stands for Quick Setting – Grade 1h, reflecting its high-performance formula designed for immediate bond development and quick trafficability.

Formulated using a carefully selected blend of bitumen, emulsifiers, and water, QS-1h delivers outstanding performance in hot climates and on dry, dusty aggregates, where anionic emulsions typically perform best. Its quick setting behaviour ensures reduced downtime and faster project turnaround, making it a preferred choice for contractors working on time-sensitive road infrastructure tasks.

This emulsion is applied cold, eliminating the need for heating, which increases safety, reduces energy consumption, and simplifies handling on-site. Whether used for minor repair work or larger surface treatment projects, QS-1h offers reliable, durable results with minimal preparation.
