Bitumen Emulsifiers
Bitumen emulsifiers are specialty chemical agents used to produce stable mixtures of bitumen and water for use in road construction and maintenance. They enable bitumen to be applied at lower temperatures, improving safety, energy efficiency, and application control.
At Opal Paints Products Pvt. Ltd., we manufacture cationic bitumen emulsifiers suitable for rapid-setting, medium-setting, and slow-setting grades. These emulsifiers are formulated to ensure excellent coating on aggregates, long storage stability, and optimal adhesion properties, even in challenging conditions.
Bitumen is naturally hydrophobic and highly viscous, which makes it difficult to apply directly. Without emulsification, heating is required—leading to safety hazards, energy consumption, and environmental impact. Emulsifiers allow the bitumen to disperse in water and be applied cold, especially for surface dressing, patch repairs, and tack coats.
Bitumen emulsifiers reduce the surface tension between bitumen and water, forming a stable emulsion with fine droplets. Depending on their ionic charge (cationic or anionic), they facilitate controlled breaking and setting when applied to aggregates, ensuring good adhesion and waterproofing properties. Opal’s emulsifiers are engineered for high performance across diverse roadwork conditions.
Benefits of Bitumen Emulsifiers
Bitumen emulsifiers play a key role in modern road construction by enabling cold application, improving adhesion, and promoting cost-efficient and eco-friendly asphalt mixes.
Improved Mixing Efficiency
Bitumen emulsifiers help produce stable emulsions that mix uniformly with aggregates at lower temperatures, reducing energy use and equipment wear.
Enhanced Adhesion & Performance
They promote better bonding between bitumen and aggregates, resulting in stronger, more durable road layers even under high stress conditions.
Cold Application Compatibility
Enables cold mix asphalt production, making it suitable for patchwork, rural roads, and maintenance in areas without access to hot mix plants.
Faster Setting Times
Specialized emulsifiers allow for controlled breaking and setting of emulsions, enabling quicker construction and reopening of roads.
Eco-Friendly Process
Lower production temperatures mean reduced emissions and fuel consumption, making emulsified bitumen a greener paving solution.
All-Weather Usability
Can be applied in cooler or moist climates, extending the construction season and enabling road repairs in challenging environments.
