Description

Ammonium Diisononylnaphthalenesulphonate is a specialized anionic surfactant derived from naphthalene. This compound is valued for its excellent wetting, dispersing, and emulsifying properties in demanding industrial formulations. It is primarily utilized by manufacturers in the agrochemical, coatings, and construction chemical industries where robust performance in complex systems is required.

Application

• Agrochemical Formulations: Acts as a key wetting and dispersing agent in pesticide and herbicide concentrates, improving stability and efficacy.
• Industrial Coatings & Inks: Used as a pigment dispersant and grinding aid to enhance color development and prevent settling.
• Construction Chemicals: Serves as a plasticizer and air-entraining agent in concrete admixtures and cementitious systems.
• Textile Processing: Functions as a leveling and scouring agent in dyeing and finishing operations.
• Metalworking Fluids: Employed as an emulsifier and corrosion inhibitor in synthetic and semi-synthetic coolants.
• Oilfield Chemicals: Used in drilling muds and completion fluids for its dispersing and anti-caking properties.
• Industrial Cleaners: Provides effective wetting and degreasing power in heavy-duty alkaline and acidic cleaner formulations.

Quality Control

Our Ammonium Diisononylnaphthalenesulphonate is manufactured under a strict quality management system. Each batch is tested to ensure consistent performance and meets specifications for critical parameters such as active matter content, pH, and ionic character. A Certificate of Analysis (COA) is provided with every shipment to guarantee traceability and compliance with your technical requirements.

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); keep the container tightly sealed when not in use to prevent absorption of atmospheric moisture, which may affect product performance.
