Description

Ammonium Naphthalenesulphonate is an organic ammonium salt derived from naphthalenesulfonic acid, valued for its excellent dispersing and wetting properties. This compound is crucial in industrial processes where the stabilization of fine particles in aqueous systems is required. It serves as a key intermediate and functional additive for manufacturers in the textile, construction, and agrochemical sectors, ensuring consistent product performance and process efficiency.

Application

• Concrete Admixtures: Acts as a highly effective plasticizer and water-reducing agent to improve the workability and strength of concrete mixes.
• Textile Auxiliaries: Used as a dispersing and leveling agent in dyeing processes to ensure uniform color uptake and fastness.
• Agricultural Formulations: Functions as a wetting and dispersing agent in pesticide and herbicide suspensions and wettable powders (WP).
• Pigment & Dye Manufacturing: Serves as a grinding aid and dispersant to prevent agglomeration and maintain color stability in pigment pastes.
• Oilfield Chemicals: Employed as a mud dispersant and fluid loss control additive in drilling fluid formulations.
• Industrial Cleaning: Enhances the wetting and penetrating power of alkaline and acidic cleaning solutions.

Quality Control

Our Ammonium Naphthalenesulphonate is manufactured under a stringent quality management system to ensure batch-to-batch consistency and performance reliability. The product undergoes comprehensive analytical testing, including assay, moisture content, and pH determination, to meet defined industrial specifications. A Certificate of Analysis (COA) documenting all critical parameters is provided with each shipment 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). This material is hygroscopic (moisture-sensitive); the container must be kept tightly sealed after initial use to prevent caking or degradation due to moisture absorption.
