Description

Asphalt, Sulfonated, Sodium Salt is a specialized anionic surfactant derived from petroleum asphalt through sulfonation and subsequent neutralization. This compound is valued for its excellent emulsifying, dispersing, and surface-active properties in demanding industrial environments. It is primarily utilized in sectors such as oilfield chemicals, construction materials, and asphalt modification, where its ability to stabilize complex mixtures is critical.

Application

• Oilfield Drilling Fluids: Acts as a fluid loss control additive and emulsifier in water-based and oil-based mud systems.
• Asphalt Emulsions: Serves as a key emulsifying agent for producing cationic or anionic asphalt emulsions used in road construction and chip sealing.
• Construction Chemicals: Used as a dispersant and plasticizer in cementitious systems and concrete admixtures.
• Roofing and Waterproofing: A component in formulations for modified bitumen membranes and waterproofing coatings.
• Pelletizing and Agglomeration Aid: Functions as a binder and surface modifier in the agglomeration of fine powders, such as in ore processing.
• Corrosion Inhibitor Formulations: Employed in protective coatings and industrial treatment fluids for metal surfaces.
• Textile and Leather Processing: Used as a wetting agent and dispersant in dyeing and finishing operations.

Quality Control

Our Asphalt, Sulfonated, Sodium Salt is manufactured under a strict quality management system. Each batch is tested against key parameters including sulfonation degree, active matter content, solubility, and pH to ensure consistent performance. Certificates of Analysis (COA) documenting these results are available upon request, providing full traceability and compliance with relevant industrial specifications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). This material is hygroscopic (moisture-sensitive); the container must be kept tightly sealed to prevent absorption of atmospheric moisture, which can affect product performance.
