Description

Nekal CAS NO 12653-75-7 is a high-performance anionic surfactant belonging to the alkyl naphthalene sulfonate family, widely recognized for its excellent wetting, dispersing, and emulsifying properties. Its primary value lies in its ability to significantly reduce surface tension in aqueous systems, enhancing process efficiency and product performance across numerous industrial applications. This chemical is essential for manufacturers in the textile, agrochemical, and construction industries seeking reliable and effective formulation aids.

Application

• Textile Processing: Acts as a powerful wetting agent and penetrant in desizing, scouring, bleaching, and dyeing baths to ensure uniform treatment of fibers.
• Agrochemical Formulations: Used as a dispersing and wetting agent in the production of wettable powders (WP), suspension concentrates (SC), and other pesticide formulations.
• Construction Chemicals: Serves as a plasticizer and air-entraining agent in cement and concrete admixtures to improve workability and durability.
• Paints & Coatings: Functions as a pigment dispersant and grinding aid to achieve stable, uniform color dispersion and prevent settling.
• Leather Processing: Employed in soaking, liming, and dyeing stages to improve the penetration of chemicals into hides.
• Paper & Pulp Industry: Utilized as a de-inking agent and dispersant in paper recycling and pulp processing operations.
• Industrial Cleaners: A key component in heavy-duty detergent formulations for its superior wetting and soil-suspending capabilities.
