Description

Benzenesulfonic Acid, Hydroxy-, Polymer With Formaldehyde And Urea is a synthetic, water-soluble anionic polyelectrolyte, commonly known as a sulfonated phenol-formaldehyde-urea co-condensate. This specialized polymer is valued for its excellent dispersing and complexing properties in aqueous systems, making it a critical performance additive. It is primarily utilized in industries requiring superior scale inhibition, dispersion of particulate matter, and stabilization of colloidal systems. The CAS number for this compound is 9041-04-7.

Application

• Water Treatment: Acts as a highly effective scale inhibitor and dispersant for calcium carbonate, calcium sulfate, and other inorganic salts in cooling water, boiler water, and reverse osmosis systems.
• Construction & Concrete: Used as a superplasticizer and grinding aid in cement and concrete admixtures to improve workability, reduce water content, and enhance early strength development.
• Textile & Dyeing: Serves as a dispersing agent for dyes and pigments, ensuring uniform color distribution and preventing agglomeration during the dyeing process.
• Paper & Pulp Industry: Functions as a retention aid and dispersant to improve fiber and filler retention, drainage, and overall paper sheet formation.
• Ceramics & Clay Processing: Employed as a deflocculant to reduce the viscosity of clay slips, allowing for better casting and shaping with lower water content.
• Oilfield Chemicals: Utilized in drilling mud formulations and oilfield water treatment as a viscosity modifier and scale control agent.
• Industrial Cleaning: Incorporated into detergent and cleaning formulations for its sequestering power against hardness ions like calcium and magnesium.
• Agriculture: Can be used as a dispersant in pesticide and herbicide formulations to improve stability and application efficiency.

Storage

Preserve in a tightly closed container, protected from light. This material is hygroscopic (moisture-sensitive). Store in a cool, dry, and well-ventilated area at room temperature (15-25°C/59-77°F). Keep the container tightly sealed when not in use to prevent absorption of atmospheric moisture, which may lead to caking or changes in viscosity.
