Description

Ammonium Dodecyl Hydrogen Phosphate is an organophosphorus compound that functions as an effective anionic surfactant and corrosion inhibitor. This chemical is valued for its ability to form stable, self-assembled monolayers on metal surfaces, providing excellent protection and surface modification properties. It is primarily utilized in industrial sectors requiring advanced metal treatment, lubrication, and specialized formulation chemistry.

Application

• Metalworking Fluids & Corrosion Inhibitors: A key component in synthetic and semi-synthetic coolants and lubricants to protect ferrous and non-ferrous metals from rust and wear.
• Surface Treatment & Conversion Coatings: Used in pre-treatment processes to enhance paint adhesion and provide a temporary protective layer on steel, aluminum, and galvanized surfaces.
• Specialty Detergents & Cleaners: Acts as a surfactant and anti-redeposition agent in industrial and institutional cleaning formulations for hard surfaces.
• Textile & Leather Processing: Functions as an emulsifier, softener, and antistatic agent in fiber lubrication and finishing baths.
• Personal Care & Cosmetics: Employed as a mild surfactant and emulsifying agent in select rinse-off products like shampoos and body washes.
• Oilfield Chemicals: Used in drilling muds and production chemicals as a corrosion inhibitor and scale control additive.
• Pigment & Filler Dispersion: Aids in the wetting and stabilization of inorganic particles in coatings, inks, and plastic masterbatches.
• Laboratory & Research: Serves as a model compound for studying self-assembled monolayers (SAMs) and surface chemistry.

Quality Control

Our Ammonium Dodecyl Hydrogen Phosphate is manufactured under a strict quality management system. Each batch undergoes comprehensive analytical testing to ensure consistent purity, performance, and compliance with agreed specifications. A Certificate of Analysis (COA) documenting key parameters such as assay, pH, and moisture content is provided with every shipment.

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); keep the container tightly sealed when not in use to prevent absorption of atmospheric moisture. Separate from strong oxidizing agents.
