Description

Benzenesulfonic Acid, Hydroxy-, Polymer With Formaldehyde And Urea, Sodium Salt is a synthetic, water-soluble anionic polymer derived from the condensation of hydroxybenzenesulfonic acid, formaldehyde, and urea. This compound is valued for its excellent dispersing, sequestering, and scale-inhibiting properties in aqueous systems. It is primarily utilized in industrial water treatment, construction, and textile processing where control of mineral deposits and particulate matter is critical.

Application

• Industrial Water Treatment: Acts as a highly effective dispersant and antiscalant in cooling water, boiler water, and reverse osmosis systems to prevent calcium carbonate and sulfate scale formation.
• Construction Chemicals: Used as a superplasticizer and grinding aid in cement and concrete admixtures to improve workability and reduce water content.
• Textile Processing: Serves as a dispersing agent in dyeing processes to ensure uniform color distribution and prevent agglomeration of dyes.
• Pigment & Filler Dispersion: Enhances the stability and homogeneity of suspensions in paints, coatings, and ceramic slurries.
• Detergent & Cleaning Formulations: Functions as a builder and sequestrant to inactivate water hardness ions and improve cleaning efficiency.
• Paper & Pulp Industry: Applied as a dispersant to control pitch and stickies and to improve the retention of fillers and fines.
