Description

Naphthalenesulfonic Acids, Polymers With Formaldehyde And Sulfonated Phenol, Sodium Salts is a high-performance, water-soluble anionic polyelectrolyte widely used as a dispersant and plasticizer. This compound is valued for its ability to reduce viscosity, prevent agglomeration, and improve the flow properties of complex mixtures. It is a critical additive for industries requiring precise particle suspension and rheology control, such as construction, ceramics, and agrochemical formulation.

Application

• Concrete & Cement Admixtures: Acts as a highly effective superplasticizer and water reducer to enhance workability, strength, and durability of concrete mixes.
• Ceramic & Clay Processing: Serves as a powerful dispersant in ceramic slips and clay bodies to ensure uniform particle distribution and reduce casting viscosity.
• Pesticide & Agrochemical Formulations: Used as a dispersing and wetting agent in wettable powders (WP) and suspension concentrates (SC) to improve stability and application performance.
• Dye & Pigment Dispersion: Enhances the dispersion and color strength of pigments and dyes in textile, ink, and paint manufacturing.
• Oilfield & Drilling Fluids: Functions as a thinner and dispersant in water-based drilling muds to control rheology and fluid loss.
• Industrial Cleaners & Detergents: Incorporated into formulations to prevent redeposition of soil and improve cleaning efficacy.
• Gypsum & Plasterboard Production: Improves fluidity and workability of gypsum slurries, leading to better board formation and reduced water demand.
• Coal Water Slurry (CWS): Used as a dispersant to prepare stable, high-concentration coal-water mixtures for efficient transport and combustion.

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); the container must be kept tightly sealed after initial use to prevent caking and degradation due to moisture absorption.
