Description

Sodium Dimethylnaphthalenesulphonate is a versatile organic sulfonate salt widely used as a dispersant, wetting agent, and emulsifier in various industrial formulations. Its primary value lies in its ability to improve the stability and performance of complex chemical systems by reducing surface tension and preventing particle agglomeration. This product is essential for manufacturers in sectors such as agrochemicals, construction, textiles, and dye production who require reliable and effective surfactant chemistry.

Application

• Agrochemical Formulations: Acts as a key dispersant and wetting agent in pesticide and herbicide concentrates to ensure uniform spray coverage and stability.
• Construction Chemicals: Used as a plasticizer and water-reducing agent in concrete admixtures to improve workability and final strength.
• Textile Processing: Serves as a leveling and dispersing agent in dye baths to achieve even color uptake and prevent dye aggregation.
• Industrial Cleaning: Functions as a surfactant in heavy-duty cleaning and degreasing formulations for industrial equipment.
• Pigment & Dye Manufacturing: Employed as a grinding aid and dispersant to produce stable pigment pastes and dye preparations.
• Oilfield Chemicals: Utilized in drilling mud formulations and as a component in enhanced oil recovery processes.
• Paper & Pulp Industry: Acts as a dispersant for pigments and fillers to improve paper quality and production efficiency.
• Rubber & Polymer Production: Used as an emulsifier in emulsion polymerization processes and as a processing aid.

Quality Control

Our Sodium Dimethylnaphthalenesulphonate is manufactured under a stringent quality management system to ensure batch-to-batch consistency and performance reliability. Each lot is analyzed against established specifications for key parameters including active content, pH, and moisture. Certificates of Analysis (COA) documenting these results are provided with every shipment to support your quality assurance protocols.

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). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after each use to prevent absorption of atmospheric moisture, which can affect product performance.
