Description

Naphthalenesulfonic Acids, Polymers With Formaldehyde, Sulfonated 1,1'-Oxybis[Methylbenzene] And Sulfonylbis[Phenol], Ammonium Sodium Salts is a high-performance, water-soluble polymeric dispersant and surfactant. This specialized chemical is engineered to provide superior stabilization and dispersion properties in complex aqueous systems. It is a critical additive for industries requiring precise control over particle suspension, rheology modification, and surface activity.

Application

• Construction & Concrete Admixtures: Acts as a highly effective superplasticizer and water-reducing agent to improve concrete workability, strength, and durability.
• Pigment & Dye Dispersions: Provides excellent stabilization for inorganic pigments and organic dyes in aqueous formulations, preventing agglomeration and settling.
• Agricultural Formulations: Used as a dispersing and wetting agent in wettable powders (WP), suspension concentrates (SC), and other agrochemical products.
• Textile & Leather Processing: Serves as a leveling agent, dispersant for dyes, and auxiliary in various wet-processing stages.
• Ceramics & Clay Processing: Enhances the rheology and stability of ceramic slips and clay suspensions.
• Oilfield & Drilling Fluids: Functions as a thinner and dispersant in water-based drilling muds to control viscosity and fluid loss.
• Industrial Cleaners & Detergents: Improves the suspension of soil and particulates in cleaning formulations.
• Paper & Pulp Industry: Used as a dispersant in coating colors and process chemicals.

Quality Control

Our production of Naphthalenesulfonic Acids, Polymers With Formaldehyde, Sulfonated 1,1'-Oxybis[Methylbenzene] And Sulfonylbis[Phenol], Ammonium Sodium Salts adheres to strict quality management protocols. Each batch undergoes rigorous testing for key performance indicators such as sulfonation degree, molecular weight distribution, solids content, pH, and dispersancy efficiency. Certificates of Analysis (COA) documenting these parameters are available for every shipment to ensure batch-to-batch consistency and compliance with your formulation requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C/59-77°F). This product is hygroscopic (moisture-sensitive). Keep the container tightly sealed when not in use to prevent moisture absorption and caking. Store away from incompatible materials.
