Description

Trisodium Naphthalenetrisulphonate is a high-purity, water-soluble aromatic sulfonate salt with excellent dispersing and complexing properties. This compound is valued for its ability to prevent agglomeration and scale formation in demanding industrial processes. It serves as a critical additive for manufacturers in the textile, construction, and agrochemical sectors, where consistent performance and material stability are paramount.

Application

• Textile Dyeing & Printing: Acts as a highly effective dispersing agent for vat and disperse dyes, ensuring uniform color and preventing dye aggregation.
• Concrete & Construction: Used as a key component in high-range water-reducing superplasticizers and dispersants to improve workability and strength of concrete mixes.
• Agrochemical Formulations: Enhances the stability and dispersibility of wettable powders and suspension concentrates for pesticides and herbicides.
• Industrial Cleaning: Serves as a builder and dispersant in detergent formulations for industrial and institutional cleaning, preventing redeposition of soil.
• Paper & Pulp Industry: Functions as a dispersant in paper coating formulations and in the pulping process to improve fiber separation and quality.
• Ceramics & Pigments: Aids in the dispersion of inorganic particles and pigments in slurries, ensuring homogeneity and preventing settling.

Quality Control

Our Trisodium Naphthalenetrisulphonate is manufactured under a stringent quality management system. Every batch undergoes rigorous analytical testing to ensure it meets precise specifications for purity, solubility, and performance. A comprehensive Certificate of Analysis (COA) documenting assay, impurity profile, and physical properties is provided with each shipment to guarantee traceability and compliance with your quality standards.

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 to prevent absorption of atmospheric moisture, which can lead to caking and reduced efficacy.
