Description

Sodium [[[(Heptadecafluorooctyl)Sulphonyl]Amino]Methyl]Benzenesulphonate is a high-performance fluorinated anionic surfactant and surface modifier. This compound is engineered to deliver exceptional surface tension reduction and chemical stability, particularly in demanding environments. It is a critical material for industries requiring advanced wetting, leveling, and anti-foaming properties in complex formulations.

Application

• Fluoropolymer Processing: Acts as a key surfactant and emulsifier in the polymerization of PTFE (Teflon™) and other fluoropolymers.
• Firefighting Foams (AFFF): Used as a fluorosurfactant component in aqueous film-forming foams for combating hydrocarbon fuel fires.
• Specialty Coatings & Inks: Provides superior wetting, leveling, and anti-cratering properties in high-performance coatings, inks, and varnishes.
• Textile & Leather Treatment: Imparts oil, water, and stain repellency to fabrics, carpets, and leather goods.
• Electronic Chemicals: Employed as a surfactant in photoresist strippers, etchants, and cleaning formulations for semiconductor manufacturing.
• Metal Plating & Surface Finishing: Enhances wetting and reduces surface defects in electroplating baths and metal pretreatment processes.
