Description

1-Naphthalenesulfonic Acid, Polymer With Formaldehyde, Sodium Salt is a synthetic, water-soluble polymeric dispersant and surfactant. This compound is valued for its ability to control particle size, prevent agglomeration, and improve the flow properties of solid materials in aqueous systems. It is a critical additive for industries requiring stable, high-quality dispersions and slurries, such as construction, ceramics, and agrochemical formulation.

Application

• Construction Industry: Acts as a highly effective superplasticizer and water-reducing agent in concrete and cement formulations to improve workability and strength.
• Ceramic Processing: Used as a dispersant in ceramic slips and glazes to ensure uniform particle suspension and prevent settling.
• Agrochemicals: Serves as a grinding aid and dispersant in the production of wettable powders and suspension concentrates (SC) for pesticides.
• Dye & Pigment Industry: Functions as a dispersing agent for organic pigments and dyes during their manufacturing and application processes.
• Textile Auxiliaries: Employed in dyeing and printing processes to improve color dispersion and uniformity.
• Industrial Cleaners: Used in formulation of scale and deposit control agents for boiler and cooling water treatment.
