Petra Oil’s SS-1h is a high-performance anionic slow-setting bitumen emulsion, specifically engineered for tack coat applications that demand superior adhesion and stability. SS-1h stands for Slow Setting-1 hard, denoting its slightly harder base bitumen compared to SS-1. This emulsion is ideal for use in warm climates and locations where stronger bonding is essential between pavement layers, such as highways, airport runways, and urban roads with moderate to high traffic.

The product is composed of bitumen dispersed in water with the aid of anionic emulsifiers, which carry a negative charge. This allows it to adhere effectively to positively charged surfaces like aggregates. SS-1h requires no heating and can be applied at ambient temperature, making it safer to use and more energy-efficient compared to conventional hot bitumen.

Key Specifications:

• Type: Anionic Bitumen Emulsion (SS-1h)
• Setting Time: Slow Setting – Hard grade
• Standard Compliance: IS 8887:2018
• Application Temperature: Ambient

Main Applications of SS-1h:

• Tack Coat for Bituminous Layers: Perfect for surface preparation before laying asphalt layers, ensuring strong bonding and reducing the risk of slippage or layer separation.
• Maintenance Works: Effective in fog sealing and surface rejuvenation, extending pavement life.
• Prime Coat for Low Volume Roads: Can also be used to coat granular surfaces, aiding dust suppression and enhancing binding.

Benefits of SS-1h:

• Enhanced Bonding Strength: Stronger adhesion than standard SS-1, especially under heavy load or high-temperature conditions.
• No Heating Required: Cold-applied formulation ensures safety, ease of use, and reduced operational costs.
• Environmentally Friendly: Water-based formulation minimizes harmful emissions.
• High Durability: Provides a resilient tack layer that enhances the longevity and performance of the final pavement structure.
