Petra Oil’s CSS-1 is a premium-grade cationic slow setting bitumen emulsion specifically formulated for applications requiring extended mixing time and low curing rates. The designation CSS-1 stands for Cationic Slow Setting – Grade 1, indicating its suitability for tasks such as soil stabilization, prime coating, fog sealing, and slurry seal applications where long workability and superior penetration into granular surfaces are essential.

CSS-1 is ideal for use in dusty, dry, or coarse aggregate conditions, where anionic emulsions may struggle to bond effectively. The cationic nature of this emulsion allows it to adhere excellently to a wide variety of aggregates, including slightly damp or moisture-prone surfaces. It is specifically designed for use in low-traffic areas, shoulder construction, and road rehabilitation projects, where gradual curing is beneficial for achieving deep penetration and maximum effectiveness.

Being a cold-applied emulsion, CSS-1 requires no heating, thereby enhancing on-site safety and significantly reducing energy costs. Its fine particle size and controlled viscosity allow for superior flow and spread across different surface textures, providing consistent results even in challenging environmental conditions.

Key Specifications:
