Description

Naphthalenesulfonic Acid, Butyl-, Polymer With Formaldehyde And 2-Naphthalenesulfonic Acid, Sodium Salt is a high-performance, water-soluble polymeric dispersant and surfactant. This compound is valued for its excellent ability to reduce surface tension, stabilize colloidal systems, and prevent particle agglomeration in aqueous formulations. It is a critical raw material for manufacturers in the construction, textile, agrochemical, and pigment industries seeking to enhance product performance and process efficiency.

Application

• Construction Chemicals: As a highly effective plasticizer and superplasticizer in concrete admixtures to improve workability and reduce water content.
• Pigment & Dye Dispersions: Primary dispersing agent for organic pigments, carbon black, and dyes to ensure color uniformity and stability in inks, paints, and coatings.
• Agrochemical Formulations: Used in wettable powders (WP) and suspension concentrates (SC) to improve the dispersion and suspension of active ingredients.
• Textile Auxiliaries: Functions as a leveling and dispersing agent in dyeing processes to achieve even color uptake.
• Ceramic & Clay Processing: Acts as a deflocculant to reduce viscosity and improve the flow properties of slurries.
• Oilfield Chemicals: Employed as a fluid loss additive and dispersant in drilling mud formulations.
• Industrial Cleaners: Enhances the wetting and cleaning power of detergent formulations for hard surface cleaning.
