Description

Naphthalenesulfonic Acid, 1,6-Dimethyl-, Sodium Salt, Polymer With Formaldehyde is a synthetic, water-soluble anionic polyelectrolyte derived from naphthalene. This compound is valued for its exceptional dispersing, stabilizing, and complexing properties in aqueous systems. It is a critical performance chemical for industries requiring high-efficiency water treatment, concrete admixtures, and pigment dispersion.

Application

• Concrete Superplasticizer: Acts as a high-range water reducer (HRWR) in concrete formulations, improving workability and strength while reducing water content.
• Dispersing Agent: Widely used for stabilizing pigments, dyes, and carbon black in aqueous suspensions for paints, inks, and coatings.
• Water Treatment Chemical: Functions as a scale inhibitor and dispersant in cooling water and boiler water systems to prevent mineral deposits.
• Ceramic & Clay Processing: Enhances the rheology and plasticity of ceramic slips and clay bodies.
• Textile & Leather Auxiliary: Used in dyeing processes to improve levelness and as a tanning auxiliary.
• Agricultural Formulations: Serves as a dispersant and stabilizer in wettable powder and suspension concentrate pesticides.
• Oilfield Chemicals: Employed in drilling muds and cement slurries for fluid loss control and dispersion.
• Construction Gypsum: Improves the workability and setting time of gypsum plaster and related products.
