Description

Benzenesulfonic Acid, Hydroxy-, Polymer With Formaldehyde, Phenol And Urea, Sodium Salt is a synthetic, water-soluble anionic polymer derived from a condensation reaction. 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 detergent formulations 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.
• Construction & Concrete Admixtures: Used as a superplasticizer and water-reducing agent in cement and concrete to improve workability and final strength.
• Detergent & Cleaning Formulations: Serves as a builder and dispersant to enhance cleaning efficiency by sequestering hard water ions and preventing soil redeposition.
• Textile & Dyeing Processes: Functions as a leveling agent and dispersant for dyes and pigments, ensuring uniform color application.
• Paper & Pulp Industry: Employed as a dispersant for pigments and fillers, and to control pitch and stickies.
• Oilfield Chemicals: Used in drilling muds and production chemicals as a scale inhibitor and dispersant for clays and solids.
• Ceramic & Clay Processing: Aids in the deflocculation and stabilization of slurries.

Quality Control

Our production of Benzenesulfonic Acid, Hydroxy-, Polymer With Formaldehyde, Phenol And Urea, Sodium Salt adheres to strict quality management protocols. Each batch undergoes rigorous analytical testing to ensure consistent performance in key parameters such as active content, pH, viscosity, and dispersancy. Certificates of Analysis (COA) documenting these specifications are available upon request to support your quality assurance and regulatory compliance needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). This product is hygroscopic (moisture-sensitive); the container must be kept tightly sealed after each use to prevent absorption of atmospheric moisture, which may lead to caking or reduced efficacy.
