Description

4,4,5,5,6,6,7,7,8,8,9,9,10,10,11,11,11-Heptadecafluoro-2-Hydroxyundecyl Dihydrogen Phosphate is a highly fluorinated organophosphate surfactant and intermediate, valued for its unique combination of extreme hydrophobicity and oleophobicity imparted by the perfluorinated chain. This compound is critical for creating durable, low-surface-energy coatings and materials with exceptional chemical and thermal resistance. It is primarily sought by formulators and researchers in the advanced materials, electronics, and specialty chemical industries for demanding surface modification applications.

Application

• Fluorinated Surfactant and Leveling Agent: Used in high-performance coatings, paints, and inks to improve wetting, leveling, and reduce surface defects on difficult substrates.
• Surface Modifier for Textiles and Leather: Imparts durable water, oil, and stain repellency to fabrics, carpets, and leather goods.
• Additive for Electronics and Photoresists: Enhances the performance of photoresists and anti-reflective coatings in semiconductor manufacturing by modifying surface energy.
• Intermediate for Fluorinated Polymers: Serves as a key building block in the synthesis of specialized fluoropolymers and phosphate esters with tailored properties.
• Paper and Packaging Treatment: Provides grease and moisture resistance for food packaging and specialty papers.
• Firefighting Foam Component (Legacy/Research): Historically used in the development of aqueous film-forming foams (AFFF); current applications focus on research into next-generation, environmentally conscious alternatives.
