Description

Naphthalenesulfonic Acid, Methyl-, Reaction Products With Formaldehyde, Sodium Salts is a high-performance, water-soluble polymeric dispersant and surfactant. This compound is valued for its exceptional ability to reduce surface tension, stabilize colloidal systems, and prevent agglomeration in aqueous formulations. It is a critical raw material for manufacturers in the construction, textile, and agrochemical industries seeking to improve product performance and process efficiency.

Application

• Construction Industry: As a highly effective plasticizer and superplasticizer in concrete and cement formulations to improve workability and reduce water content.
• Textile Processing: Used as a leveling agent, dispersant, and wetting agent in dyeing and printing processes to ensure uniform color distribution.
• Agrochemical Formulations: Acts as a key dispersant and stabilizer in the production of wettable powders (WP), suspension concentrates (SC), and other pesticide formulations.
• Pigment & Dye Dispersion: Essential for grinding and stabilizing organic pigments, carbon black, and ceramic colors in aqueous systems.
• Industrial Cleaning: Serves as a surfactant and builder in industrial and institutional cleaning products for enhanced soil suspension and detergency.
• Oilfield Chemicals: Utilized as a fluid loss additive and dispersant in drilling muds and cement slurries for oil and gas well operations.
• Paper Manufacturing: Functions as a dispersant for coatings and fillers like calcium carbonate and kaolin clay.
• Leather Tanning: Employed as a dyeing auxiliary and dispersing agent in the leather processing industry.
