Description

2-Naphthalenesulfonic Acid, 6-Hydroxy-, Polymer With Formaldehyde And Methylphenol, Sodium Salt is a synthetic, water-soluble polymeric dispersant and complexing agent. This specialized chemical is engineered to provide superior performance in controlling scale and particulate matter in aqueous systems. It is a critical component for formulators and process engineers in industries requiring high-efficiency water treatment and dispersion. The product is supplied as a high-purity, consistent-grade material to ensure reliable performance in demanding applications.

Application

• Industrial Water Treatment: Primary use as a highly effective scale inhibitor and dispersant in cooling water, boiler water, and reverse osmosis systems to prevent calcium carbonate, sulfate, and phosphate scales.
• Construction Chemicals: Key additive in concrete admixtures and cement grinding aids to improve fluidity, reduce water content, and enhance the dispersion of solid particles.
• Textile & Dyeing Auxiliary: Acts as a leveling agent and dispersant for dyes and pigments, ensuring uniform color distribution and preventing agglomeration.
• Pigment & Filler Dispersion: Used in the manufacture of paints, coatings, inks, and ceramics to stabilize pigment suspensions and improve color strength and gloss.
• Oilfield Chemicals: Employed in drilling muds and completion fluids as a thinner and dispersant to control rheology and prevent clay flocculation.
• Detergent & Cleaning Formulations: Functions as a builder and anti-redeposition agent to enhance cleaning efficiency by sequestering hardness ions and keeping soil in suspension.
• Paper Manufacturing: Used as a retention aid and dispersant in pulp processing to improve sheet formation and dewatering.

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). Keep the container tightly sealed when not in use to prevent absorption of atmospheric moisture, which may lead to caking or reduced flowability. Keep away from strong oxidizing agents.
