Description

(2-Carboxyethyl)Dimethyl-3-[Methyl[(3,3,4,4,5,5,6,6,7,7,8,8,8-Tridecafluorooctyl)Sulphonyl]Amino]Propylammonium Hydroxide is a high-value, specialized fluorinated surfactant and zwitterionic compound. Its unique structure, featuring a long perfluorinated chain and a betaine-like head group, provides exceptional surface activity and stability in demanding environments. This chemical is essential for industries requiring advanced performance in coatings, electronics, and specialty materials where low surface tension, chemical resistance, and compatibility are critical. The compound is supplied with CAS No. 66008-72-8.

Application

• Fluorinated Surfactant & Leveling Agent: A key additive in high-performance fluoropolymer coatings, paints, and varnishes to reduce surface tension and improve wetting and film formation.
• Electroplating & Metal Finishing: Used in specialized electroplating baths to enhance surface uniformity, reduce pitting, and improve the quality of metal deposits.
• Fire-Fighting Foams (AFFF): A potential component in the formulation of aqueous film-forming foams (AFFF) for combating flammable liquid fires, leveraging its fluorinated tail.
• Textile & Leather Treatment: Imparts oil, water, and stain repellency to fabrics, carpets, and leather goods.
• Electronic Chemicals: Acts as a surfactant in photoresist developers, etching solutions, and cleaning formulations for semiconductor manufacturing.
• Specialty Polymer Additive: Incorporated into fluoropolymers and other high-performance plastics to modify surface properties and improve processability.
• Oil & Gas Field Chemicals: Used in formulations for enhanced oil recovery, drilling fluids, and as a corrosion inhibitor in harsh downhole conditions.
