Description

Diammonium 4,4,5,5,6,6,7,7,8,8,9,9,10,10,11,11,11-Heptadecafluoro-2-Hydroxyundecyl Phosphate is a specialized fluorinated phosphate ester salt, a high-performance surfactant and surface modifier. Its unique structure, featuring a long perfluorinated chain linked to a phosphate group, provides exceptional surface tension reduction, oil and water repellency, and chemical stability. This compound is essential for manufacturers requiring advanced performance in demanding industrial and specialty chemical applications. Its CAS number is 94200-45-0.

Application

• Fluorinated Surfactant & Leveling Agent: A critical component in high-performance coatings, inks, and polymer dispersions to improve wetting, leveling, and reduce surface defects.
• Oil & Water Repellent Finishes: Used in textile and leather treatment formulations to impart durable stain and liquid repellency.
• Firefighting Foam Concentrates (AFFF/FP): Serves as a key fluorosurfactant in aqueous film-forming foam formulations for rapid fire suppression of flammable liquid fires.
• Specialty Additive for Electronics: Employed in photoresist developers and electronic coating formulations to enhance surface uniformity and processing performance.
• Metal Treatment & Plating: Functions as a wetting agent and additive in metal cleaning, pretreatment, and electroplating baths to improve surface quality.
• Paper & Packaging Coatings: Imparts grease and oil resistance to specialty papers, cardboard, and food packaging materials.
