Description

(2-Carboxyethyl)Dimethyl-3-[[(3,3,4,4,5,5,6,6,7,7,8,8,8-Tridecafluorooctyl)Sulphonyl]Amino]Propylammonium Hydroxide is a highly specialized fluorinated surfactant and zwitterionic compound. Its unique structure, featuring a long perfluorinated chain and a betaine-like head group, provides exceptional surface activity, thermal stability, and chemical resistance. This product is essential for industries requiring advanced performance in extreme environments or where standard hydrocarbon surfactants fail. Key applications include high-performance coatings, advanced polymer processing, and specialized electronics manufacturing.

Application

• Fluoropolymer Processing Aid: Acts as a critical surfactant and dispersion agent in the emulsion polymerization of PTFE, FEP, and PFA, improving particle size control and stability.
• High-Performance Coatings & Inks: Used as a leveling and wetting agent in fluorinated coatings, paints, and inks to enhance surface coverage, reduce defects, and provide oil/water repellency.
• Electronics & Semiconductor Manufacturing: Serves as a surfactant in photoresist strippers, cleaning formulations, and etching solutions for silicon wafers, leveraging its chemical inertness and low surface tension.
• Fire-Fighting Foams (Legacy/Formulation R&D): Historically used as a key fluorosurfactant component in aqueous film-forming foams (AFFF) for creating stable, fast-spreading films on hydrocarbon fuels.
• Specialty Detergents & Cleaners: Formulated into industrial cleaners for removing stubborn, oily soils from metals, glass, and ceramics due to its powerful surfactant properties.
• Textile & Leather Treatment: Imparts durable water, oil, and stain repellency to fabrics, carpets, and leather goods.
• Advanced Material Synthesis: Functions as an emulsifier and phase-transfer catalyst in the synthesis of fluorinated organic compounds and nanomaterials.
