Description

Benzenesulfonic Acid, Hydroxy-, Monosodium Salt, Polymer With Formaldehyde And Urea is a synthetic, water-soluble anionic polymer derived from a condensation reaction. This specialized chemical is engineered to function as a highly effective dispersant and scale inhibitor in demanding aqueous systems. It is primarily utilized by industrial manufacturers in sectors such as water treatment, textile processing, and construction materials, where controlling mineral deposits and stabilizing particulate suspensions is critical for process efficiency and product quality.

Application

• Industrial Water Treatment: Acts as a key anti-scalant and dispersant in cooling water, boiler water, and reverse osmosis systems to prevent the precipitation of calcium carbonate, calcium sulfate, and other inorganic salts.
• Textile Auxiliaries: Used in dyeing and printing processes to improve color dispersion, levelness, and fastness, while also helping to prevent dye agglomeration.
• Construction Chemicals: Incorporated as a plasticizer and water-reducing agent in cement and concrete formulations to improve workability and final strength.
• Pigment & Filler Dispersion: Enhances the stability and uniformity of inorganic pigments and fillers (e.g., clay, calcium carbonate) in slurry preparations for paints, coatings, and paper manufacturing.
• Oil Field Chemicals: Employed in drilling muds and production chemicals to control scale formation and improve fluid performance.
• Detergent & Cleaning Formulations: Serves as a builder and anti-redeposition agent to enhance cleaning power and prevent soil from re-adhering to fabrics or surfaces.
