Description

Potassium Diisopropylnaphthalenesulphonate is an organic potassium salt widely used as a high-performance surfactant and dispersing agent. Its value lies in its excellent wetting, emulsifying, and solubilizing properties, making it a critical component in complex formulations. This product is essential for manufacturers in the agrochemical, dye, pigment, and polymer industries who require stable and effective dispersion systems.

Application

• Agrochemical Formulations: Acts as a key wetting agent and dispersant in pesticide and herbicide concentrates (SCs, WGs, WPs) to ensure uniform coverage and stability.
• Dye and Pigment Industry: Serves as a primary dispersant for organic pigments and dyes, preventing agglomeration and improving color strength and consistency.
• Polymerization Processes: Used as an emulsifier and particle stabilizer in emulsion polymerization for synthetic rubbers, plastics, and latex production.
• Industrial Cleaners & Detergents: Functions as a surfactant in heavy-duty cleaning formulations, enhancing penetration and soil removal.
• Textile Processing: Employed as a leveling and dispersing agent in dye baths to achieve even coloration.
• Construction Chemicals: Aids in the dispersion of solids in cement additives and concrete admixtures.
