Description

1,1,2,2,3,3,4,4,4-Nonafluoro-N,n-Bis(2-Hydroxyethyl)Butane-1-Sulphonamide is a specialized perfluorinated sulfonamide derivative, engineered to deliver exceptional surface activity and chemical stability. Its unique molecular structure, featuring a perfluorobutyl chain and hydrophilic hydroxyethyl groups, makes it a high-performance surfactant and intermediate for demanding applications. This compound is primarily sought by formulators and researchers in the fluorochemical, coatings, and specialty polymer industries for its ability to impart oil, water, and stain repellency.

Application

• Fluorinated Surfactant & Leveling Agent: A key ingredient in high-performance coatings, paints, and inks to improve wetting, flow, and surface leveling on difficult substrates.
• Polymer & Resin Modification: Used as a functional monomer or additive to introduce fluorinated segments into polymers, enhancing their chemical resistance, durability, and surface properties.
• Oil & Stain Repellent Finishes: Serves as a critical intermediate in the synthesis of durable water and oil repellent (DWR) treatments for textiles, leather, and carpets.
• Firefighting Foam Concentrates (Historical/Precursor): As a perfluorinated sulfonamide derivative, it is related to chemistry historically used in the development of aqueous film-forming foams (AFFF).
• Specialty Chemical Intermediate: Utilized in organic synthesis to build more complex fluorinated molecules for pharmaceuticals, agrochemicals, and electronic materials.
• Surface Treatment for Electronics: Applied in formulations to create hydrophobic and insulating coatings for electronic components and circuit boards.
