Description

[3-[[(Heptadecafluorooctyl)Sulphonyl](3-Sulphopropyl)Amino]Propyl](2-Hydroxyethyl)Dimethylammonium Hydroxide is a high-performance, fluorinated zwitterionic surfactant with a unique molecular structure combining perfluoroalkyl and sulphobetaine functionalities. This compound matters for its exceptional ability to dramatically lower surface tension in aqueous and organic systems, providing superior wetting, leveling, and anti-static properties. It is critically needed by formulators in industries such as advanced coatings, electronics, and high-performance materials where extreme surface activity and chemical resistance are required.

Application

• Advanced Coating Additive: Used as a powerful wetting and leveling agent in fluoropolymer coatings, paints, and inks to improve substrate adhesion and film uniformity.
• Electronics Manufacturing: Employed in photoresist developers and cleaning formulations for semiconductor wafers and electronic components due to its low surface tension and anti-static effects.
• Fire-Fighting Foams (AFFF): A key fluorosurfactant component in aqueous film-forming foams (AFFF) for combating flammable liquid fires.
• Textile and Fiber Treatment: Provides oil, water, and stain repellency to fabrics, carpets, and technical textiles.
• Specialty Cleaning & Polishing: Formulated into high-performance cleaners, polishes, and degreasers for hard surfaces where low residue and high spreading are critical.
• Polymerization Aid: Acts as an emulsifier or surfactant in the emulsion polymerization of fluorinated monomers.
• Biomedical & Diagnostic Reagents: Utilized in specific diagnostic assays and surface modifications where bio-inert, low-binding properties are needed.
