Petra Oil’s CSS-1h is a high-performance, slow setting cationic bitumen emulsion designed for specialized applications requiring prolonged workability, enhanced adhesion, and consistent penetration across a wide range of surfaces. The “h” in CSS-1h stands for High Performance, reflecting its upgraded formulation for more demanding tasks in both new road construction and preventive maintenance.

CSS-1h is ideal for fog sealing, prime coating, slurry seal mixtures, and soil stabilization—particularly in environments where surface conditions are highly variable or where extended mixing and curing time is required. The cationic nature of the emulsion allows it to bind effectively with both wet and dusty aggregates, making it highly versatile for use in semi-urban and rural roads, construction shoulders, and base stabilization projects.

What sets CSS-1h apart is its improved residual binder properties, which allow for deeper penetration into granular surfaces, resulting in stronger, longer-lasting road layers. Its fine particle size ensures smooth distribution, while its high-performance emulsifier system prevents premature breaking, giving construction teams ample time to mix and apply.

As a cold-applied emulsion, CSS-1h is energy-efficient, safe to handle, and cost-effective—particularly valuable in remote or low-infrastructure regions where heating equipment is unavailable.

Key Specifications:

• Type: Cationic Bitumen Emulsion (CSS-1h)
• Setting Time: Slow Setting
• Standard Compliance: IS 8887:2018
• Application Temperature: Ambient (Cold Application)

Main Applications of CSS-1h:

• Fog Seal on Aged Pavement: Restores surface flexibility and seals micro-cracks.
• Soil Stabilization: Used for strengthening subgrades and unpaved surfaces.
• Prime Coat for Granular Bases: Ensures better bond with subsequent layers.
• Slurry Seal Binder: Core component in slurry and micro-surfacing formulations.

Benefits of CSS-1h:

• High Workability Time: Ideal for large or complex surface treatments.
• Enhanced Penetration: Provides deeper and stronger binding with granular materials.
• Cold Applied: Safe, efficient, and environmentally friendly application.
• Weather-Resistant: Performs reliably under varied climate conditions.
• Long-Lasting Results: Improves road surface durability and reduces maintenance needs.
