Description

Benzenesulfonic Acid, Dimethyl-, Polymer With Formaldehyde, Sodium Salt is a synthetic, water-soluble anionic polyelectrolyte derived from the condensation polymerization of dimethylbenzenesulfonic acid with formaldehyde. This compound matters as a highly effective dispersant and stabilizer, offering superior performance in controlling particle agglomeration and maintaining system homogeneity. Industries requiring advanced formulation stability, such as construction materials, agrochemicals, and water treatment, need this reliable additive to enhance product performance and process efficiency.

Application

• Construction Industry: Primary use as a high-range water reducer and superplasticizer in concrete and cement formulations to improve workability and final strength.
• Agrochemical Formulations: Acts as a key dispersant and stabilizer in wettable powders, suspension concentrates (SC), and water-dispersible granules (WG) for pesticides and herbicides.
• Industrial & Institutional Cleaners: Functions as a surfactant and anti-redeposition agent in powder and liquid detergent formulations.
• Textile & Leather Processing: Utilized as a dye dispersant and leveling agent to ensure uniform color application.
• Water Treatment Systems: Serves as an anti-scalant and dispersant for controlling mineral deposits in cooling and boiler water systems.
• Ceramics & Pigments: Employed to stabilize slurries and prevent the settling of solid particles during manufacturing and processing.
