Description

Heptadecafluoro-n-(2-Hydroxyethyl)-n-Methylisooctanesulphonamide is a high-performance fluorinated surfactant and chemical intermediate characterized by its unique perfluorinated alkyl chain and polar sulfonamide head group. This compound is engineered to deliver exceptional surface tension reduction, chemical stability, and oil/water repellency in demanding formulations. It is a critical raw material for industries requiring advanced fluorochemical properties, including coatings, firefighting foams, and specialty polymer synthesis.

Application

• Aqueous Film-Forming Foam (AFFF) Concentrates: A key fluorosurfactant component for generating high-performance, fast-spreading firefighting foams used on hydrocarbon fuel fires.
• Fluoropolymer Processing Aids: Acts as a surfactant and leveling agent in the emulsion polymerization of fluoropolymers like PTFE and PVDF.
• Stain-Resistant & Oil-Repellent Coatings: Imparts durable water, oil, and stain repellency to textiles, carpets, paper, and leather.
• Specialty Cleaning & Etching Formulations: Used in precision cleaning solutions and semiconductor etching baths where low surface tension and chemical inertness are required.
• Lithographic Printing Inks & Coatings: Enhances leveling and substrate wetting in high-performance printing applications.
• Chemical Intermediate: Serves as a building block for synthesizing more complex fluorinated surfactants, monomers, and pharmaceuticals.
