Description

4-[2-[2-[2-[2-[n-Propyl-n-(Heptadecafluorooctyl)Sulfonylamino]Ethoxy]Ethoxy]Ethoxy]Ethoxy]Butane-1-Sulfonic Acid Sodium Salt is a high-performance fluorinated anionic surfactant and electrolyte, valued for its exceptional surface activity and chemical stability derived from its unique perfluorinated tail. This compound is engineered to provide superior wetting, leveling, and anti-foaming properties in demanding formulations. It is primarily sought after by manufacturers in the electronics, coatings, and specialty polymer industries for advanced material processing.

Application

• Electroplating & Metal Finishing: As a critical wetting agent and leveler in high-performance fluorinated electrolyte baths for chrome plating and other metal deposition processes.
• Lithography & Photoresist Formulations: Used as a surfactant in photoresist developers and rinse solutions for semiconductor manufacturing to ensure uniform coating and defect reduction.
• Fluoropolymer Synthesis & Processing: Acts as an emulsifier and stabilizer in the polymerization of fluorinated monomers (e.g., PTFE, PFA) and as a processing aid.
• Specialty Coatings & Inks: Imparts improved flow, leveling, and substrate wetting in high-value fluoropolymer coatings, paints, and inks.
• Fire-Fighting Foams (AFFF): A key fluorosurfactant component in aqueous film-forming foams (AFFF) for combating flammable liquid fires.
• Chemical Mechanical Planarization (CMP): Employed as an additive in CMP slurries for advanced semiconductor wafer polishing to control surface wetting and particle dispersion.
