Description

Diisobutylnaphthalenesulfonate is a specialized anionic surfactant and dispersing agent derived from naphthalene. This compound is valued for its excellent wetting, emulsifying, and solubilizing properties in demanding industrial formulations. It is a critical component for manufacturers in sectors requiring high-performance surface-active agents, such as agrochemicals, construction materials, and specialty coatings.

Application

• Agrochemical Formulations: Acts as a key wetting agent, dispersant, and penetrant in pesticides, herbicides, and fungicides to enhance efficacy and stability.
• Construction Chemicals: Used as a plasticizer and air-entraining agent in concrete admixtures and cement grinding aids to improve workability and durability.
• Industrial Cleaners & Degreasers: Serves as a powerful surfactant in heavy-duty cleaning formulations for machinery, metal parts, and hard surfaces.
• Textile Processing: Functions as a leveling agent, dispersant, and wetting agent in dyeing and finishing processes to ensure uniform color and treatment.
• Oilfield Chemicals: Employed as an emulsifier and dispersant in drilling muds and production chemicals to control viscosity and prevent agglomeration.
• Paints & Coatings: Utilized as a pigment grinding aid and dispersant to prevent settling and ensure consistent color and gloss in final products.
• Leather Processing: Aids in the wetting and penetration of fats, dyes, and tanning agents for uniform treatment of hides.
• Paper & Pulp Industry: Acts as a dispersant for pigments and resins in coating formulations to improve paper quality and printability.
