Description

n-Ethyl-n-[(Heptadecafluorooctyl)Sulphonyl]Glycine is a high-performance fluorinated surfactant and anionic perfluorooctane sulfonate (PFOS) derivative. This compound is valued for its exceptional ability to dramatically lower surface tension in aqueous and organic systems, providing superior wetting, leveling, and anti-foaming properties. It is a critical raw material for industries requiring advanced surface modification, including high-performance coatings, specialized polymer processing, and advanced fire-fighting foams.

Application

• Fluorinated Polymer Synthesis: Acts as a key surfactant and emulsifier in the emulsion polymerization of fluoropolymers like PTFE (Teflon®) and FEP.
• High-Performance Coatings & Inks: Provides superior wetting, leveling, and anti-cratering properties in demanding coating formulations for electronics and industrial applications.
• Fire-Fighting Foams (AFFF): Serves as a critical component in aqueous film-forming foams (AFFF) for rapidly suppressing hydrocarbon fuel fires.
• Metal Plating & Etching: Used as a mist suppressant and wetting agent in chrome plating and other metal finishing baths to improve quality and reduce emissions.
• Specialty Cleaning & Degreasing: Formulated into industrial cleaners for its ability to penetrate and displace oils and greases from sensitive substrates.
• Textile & Leather Treatment: Imparts oil, water, and stain repellency to fabrics and leather goods.
