Description

Sodium 3-[[3-[[(Heptadecafluorooctyl)Sulphonyl]Amino]Propyl]Methylamino]Propanesulphonate is a high-performance fluorinated anionic surfactant, distinguished by its unique perfluorooctyl chain. This compound is engineered to deliver exceptional surface tension reduction and stability in demanding environments where conventional surfactants fail. It is a critical material for industries requiring advanced wetting, leveling, and anti-foaming properties in complex formulations.

Application

• Firefighting Foams (AFFF): A key ingredient in aqueous film-forming foams for rapid knockdown and vapor suppression of flammable liquid fires.
• Specialty Coatings and Inks: Provides superior wetting, leveling, and anti-cratering properties in high-performance fluoropolymer and industrial coatings.
• Electroplating and Metal Finishing: Used as a wetting agent and mist suppressant in chromium plating and other electrochemical processes.
• Oil & Gas Production Chemicals: Functions as a fluorosurfactant in acidizing and fracturing fluids to enhance penetration and recovery.
• Photographic and Imaging Materials: Acts as a coating aid and anti-static agent in the production of films and papers.
• Textile and Leather Treatment: Imparts oil, water, and stain repellency to fabrics and finished leather goods.
