Description

Benzenesulfonic Acid, Hydroxy-, Polymer With Formaldehyde, Phenol, Sulfonylbis[Phenol] And Urea, Ammonium Sodium Salt is a specialized, water-soluble polymeric dispersant and complexing agent. This engineered compound is valued for its ability to control scale formation and inhibit corrosion in demanding aqueous systems. It is primarily required by industrial water treatment and process chemistry sectors where high-performance sequestration and dispersion are critical for operational efficiency and equipment longevity.

Application

• As a high-efficiency scale inhibitor and dispersant in industrial cooling water and boiler water treatment programs.
• Used in detergent and cleaning formulations to enhance performance by sequestering hardness ions like calcium and magnesium.
• Acts as a dispersing agent for pigments, clays, and inorganic particles in various manufacturing processes.
• Employed in oilfield applications for scale control in production and water injection systems.
• Serves as a chelating agent in textile processing, pulp & paper production, and metal surface treatment baths.
• Functions in construction chemicals as a plasticizer and water-reducing agent in concrete admixtures.

Quality Control

Our products undergo rigorous quality testing to ensure compliance with industry standards. Every batch is controlled against key parameters such as active content, pH, viscosity, and ionic character to guarantee consistent performance. Certificates of Analysis (COA) are available upon request, providing full traceability and batch-specific data.

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 material is hygroscopic (moisture-sensitive); ensure containers are sealed immediately after use to prevent absorption of atmospheric moisture which may affect product performance.
