Description

n-Allylheptadecafluorooctanesulphonamide is a specialized fluorinated sulfonamide derivative characterized by its unique perfluorooctyl chain and reactive allyl group. This compound is valued for its ability to impart exceptional oil, water, and stain repellency, as well as chemical resistance, to various materials. It serves as a critical intermediate for the synthesis of high-performance surfactants, surface modifiers, and functional polymers, primarily targeting the textile finishing, advanced coatings, and specialty chemical manufacturing industries.

Application

• Fluorinated Surfactant & Polymer Intermediate: A key building block for synthesizing perfluorinated surfactants and polymers used in demanding applications.
• Textile & Fiber Treatment: Imparts durable water, oil, and stain repellency to technical textiles, outdoor apparel, and upholstery fabrics.
• Surface Modifier for Coatings: Used to create low-surface-energy, chemically resistant coatings for electronics, optics, and industrial equipment.
• Paper & Packaging Coatings: Enhances grease and moisture resistance in food packaging and specialty paper products.
• Fire-Fighting Foam Formulations (Historic/Precursor): Served as a precursor in the synthesis of certain fluorosurfactants historically used in aqueous film-forming foams (AFFF).
• Research & Development: Utilized in academic and industrial R&D for developing novel fluorinated materials with specific surface properties.
