Description

Sodium Dinonyl Phosphate is an organophosphate salt widely utilized as a high-performance surfactant and corrosion inhibitor. Its value lies in its excellent surface-active properties and stability in both aqueous and non-aqueous systems, making it a versatile additive. This product is essential for formulators and manufacturers in the lubricant, metalworking, and specialty chemical industries seeking effective emulsifiers and anti-wear agents.

Application

• Primary emulsifier and surfactant in industrial lubricants and metalworking fluids.
• Corrosion inhibitor in hydraulic fluids, rust preventives, and fuel additives.
• Key component in detergent formulations and industrial cleaning products.
• Used as a dispersing agent and stabilizer in agrochemical and pesticide formulations.
• Acts as an anti-wear and extreme pressure (EP) additive in grease and gear oil formulations.
• Employed in the synthesis of specialty chemicals and as a processing aid in polymer and textile industries.

Quality Control

Our Sodium Dinonyl Phosphate is manufactured under a strict quality management system. Each batch undergoes comprehensive analytical testing to ensure consistent purity and performance. A Certificate of Analysis (COA) detailing key parameters such as assay, moisture content, and pH is provided with every shipment to guarantee compliance with your technical requirements.

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); ensure containers are kept tightly sealed to prevent absorption of atmospheric moisture. Keep away from strong bases and incompatible materials.
