Description

2-Naphthalenesulfonic Acid, 6-Hydroxy-, Polymer With Formaldehyde, 3-Methylphenol And 4-Methylphenol, 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 stability of suspensions in aqueous systems. It is a critical additive for manufacturers in the construction, textile, and pigment industries seeking to enhance product performance and process efficiency.

Application

• Cement and Concrete Admixtures: Acts as a highly effective superplasticizer and water reducer to improve workability, strength, and durability of concrete mixes.
• Pigment and Dye Dispersions: Used as a grinding aid and stabilizer to produce uniform, stable pigment pastes and dye solutions for inks, paints, and textiles.
• Ceramic Processing: Serves as a deflocculant to control the rheology of ceramic slurries, ensuring uniform casting and shaping.
• Agricultural Formulations: Employed as a dispersing agent in wettable powders and suspension concentrates to improve the stability and application of agrochemicals.
• Oilfield Chemicals: Functions as a fluid loss additive and dispersant in drilling muds to maintain wellbore stability.
• Industrial Cleaners: Enhances the cleaning efficacy of formulations by dispersing soil and preventing redeposition on surfaces.
