Description

Naphthalenesulfonic Acids, Polymers With Formaldehyde, Sulfonated 1,1'-Biphenyl And Sulfonylbis[Phenol], Ammonium Sodium Salts is a high-performance, water-soluble polymeric dispersant and surfactant. This specialized chemical is engineered to provide superior particle suspension, wetting, and stabilization properties in complex formulations. It is a critical additive for industries requiring precise control over rheology and material compatibility in aqueous systems.

Application

• Construction & Concrete Admixtures: Acts as a highly effective superplasticizer and water-reducing agent to improve the workability and strength of concrete.
• Pigment & Dye Dispersions: Used as a primary dispersant for organic pigments, carbon black, and dyes in inks, paints, and coatings to ensure color uniformity and stability.
• Agricultural Formulations: Enhances the suspension and stability of active ingredients in wettable powders (WP) and suspension concentrates (SC) for crop protection products.
• Ceramics & Clay Processing: Serves as a deflocculant to control the viscosity and improve the casting properties of ceramic slurries.
• Textile & Leather Auxiliaries: Functions as a levelling agent, dispersant, and tanning auxiliary in dyeing and finishing processes.
• Oilfield & Drilling Fluids: Utilized as a thinner and dispersant in water-based drilling muds to control rheology and fluid loss.
• Industrial Cleaners & Detergents: Improves the wetting and soil suspension properties of heavy-duty cleaning formulations.
