Description

Carboxymethyldimethyl-3-[[(3,3,4,4,5,5,6,6,7,7,8,8,8-Tridecafluorooctyl)Sulphonyl]Amino]Propylammonium Hydroxide is a specialized fluorinated surfactant and quaternary ammonium compound, engineered to deliver exceptional surface activity and stability in demanding environments. This product matters because it combines the powerful oil and water repellency of a long perfluoroalkyl chain with the ionic functionality of a betaine-like structure, making it a high-performance additive for advanced formulations. Industrial R&D and production teams in sectors requiring extreme surface modification, chemical resistance, and compatibility with fluorinated systems will find this chemical indispensable for creating next-generation materials and coatings.

Application

• Fluoropolymer Processing Aid: Acts as a surfactant and compatibilizer in the emulsion polymerization of PTFE, PVDF, and FEP, improving particle stability and dispersion.
• Oil & Water Repellent Finishes: A key ingredient in formulating high-durability, stain-resistant coatings for textiles, leather, and non-woven fabrics.
• Fire-Fighting Foam Concentrates (Historical/Specialist): Used in the formulation of aqueous film-forming foams (AFFF) and fluoroprotein foams for challenging hydrocarbon and polar solvent fires.
• Specialty Cleaning & Etching Solutions: Enhances wetting and reduces surface tension in aggressive acidic or alkaline cleaning formulations for semiconductors and metals.
• Paper & Packaging Coatings: Imparts grease resistance and barrier properties to food packaging and high-value graphical papers.
• Lithography and Photoresist Ancillaries: Serves as a surfactant additive in photoresist developers and rinse solutions to prevent defects and improve line-edge roughness.
• Enhanced Oil Recovery (EOR): Investigated as a fluorosurfactant to alter interfacial tension in reservoir flooding for improved oil displacement.
