NINGBO INNO PHARMCHEM CO.,LTD. supplies a range of specialty chemicals that are vital to various industrial applications. Among these, our cationic surfactants, including Quaterinium-27, play a significant role in asphalt emulsification, a critical process in modern road construction and maintenance.

Asphalt emulsions are mixtures of asphalt binder and water, stabilized by emulsifying agents. These emulsions offer numerous advantages over hot-mix asphalt, including easier handling at lower temperatures, reduced emissions, and suitability for a wider range of applications like chip seals, tack coats, and patching. The effectiveness of an asphalt emulsion hinges on the stability and performance of the emulsifier used.

Cationic surfactants, such as those based on imidazoline chemistry like Quaterinium-27, are widely employed as emulsifiers in asphalt applications. Their positive charge is particularly advantageous because aggregate surfaces, commonly used in road construction (like gravel and stone), often carry a negative surface charge. This opposite charge attraction leads to strong adhesion between the emulsified asphalt particles and the aggregate, a phenomenon known as adhesion promotion or coating. This ensures that the asphalt effectively binds the aggregate particles together, forming a durable road surface.

The improved dispersity and stability offered by surfactants like Quaterinium-27 are crucial for creating robust asphalt emulsions that can withstand storage and application conditions. They help to create fine, stable droplets of asphalt in water that do not readily coalesce. This leads to a more homogeneous mixture that can be easily applied and cures effectively. At NINGBO INNO PHARMCHEM CO.,LTD., we provide high-quality chemical components that contribute to the performance and longevity of road construction materials, highlighting the versatile applications of our surfactant products.
