Description

Bis[2-[n-Ethyl(Heptadecafluorooctanesulphonyl)Amino]Ethyl] Hydrogen Phosphate is a high-performance fluorinated phosphate ester surfactant and functional additive. This compound matters for its unique combination of perfluorooctanesulfonamide-derived hydrophobicity and oleophobicity with phosphate ester functionality, enabling exceptional surface activity and stability in demanding environments. It is primarily needed by formulators in the coatings, fire-fighting foams (AFFF), and specialty polymer industries, where its properties impart water and oil repellency, leveling, and emulsification.

Application

• Fire-Fighting Foams (AFFF): A key fluorosurfactant component in aqueous film-forming foams (AFFF) for rapid knockdown of hydrocarbon fuel fires.
• Protective Coatings & Paints: Used as a leveling and wetting agent to improve substrate coverage and impart water/oil repellent characteristics.
• Textile & Leather Treatment: Provides durable stain and oil resistance to fabrics, carpets, and leather goods.
• Paper & Packaging: Imparts grease resistance and release properties to food packaging and specialty papers.
• Polymers & Plastics: Acts as a processing aid and internal mold release agent for high-performance fluoropolymers and engineering plastics.
• Electronics & Semiconductor: Used in formulations for anti-fingerprint coatings and as a surfactant in photoresist developers.
