Description

Naphthalenesulfonic Acids, Polymers With Formaldehyde And 4,4'-Sulfonylbis[Phenol] CAS NO 68411-62-1 is a high-performance, synthetic polymeric dispersant and superplasticizer. This compound is engineered to provide superior water reduction and particle dispersion in complex formulations, significantly enhancing the workability and final strength of materials. It is an essential additive for industries requiring advanced rheology control and cementitious system optimization.

Application

• Primary component in high-range water-reducing admixtures (superplasticizers) for concrete and mortar.
• Dispersing agent for pigments, dyes, and carbon black in industrial coatings and inks.
• Grinding aid and viscosity modifier in the production of ceramic slurries and advanced ceramics.
• Additive for oil well drilling fluids to control rheology and fluid loss.
• Stabilizer and plasticizer in gypsum board and other construction material formulations.
• Processing aid in textile and leather auxiliaries for improved dye penetration and leveling.

Quality Control

Our products undergo rigorous quality testing to ensure compliance with industry standards for construction chemicals and dispersants. Every batch is controlled against key parameters such as sulfonation degree, molecular weight distribution, and dispersing performance. Certificates of Analysis (COA) documenting purity, solids content, pH, and specific performance tests are available upon request to support your quality assurance protocols.

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). Due to its hygroscopic nature, the container must be kept tightly sealed after each use to prevent moisture absorption, which can affect product performance.
