Description

Sodium 3-[Methyl[3-[[(Tridecafluorohexyl)Sulphonyl]Amino]Propyl]Amino]Propanesulphonate is a high-performance fluorinated anionic surfactant, valued for its exceptional surface activity and stability in harsh chemical environments. Its unique molecular structure, featuring a long perfluoroalkyl chain, provides outstanding oil and water repellency, low surface tension, and thermal/chemical resistance. This makes it a critical additive for industries requiring durable surface modification, including advanced coatings, firefighting foams, and specialty textile treatments.

Application

• Fluorinated Firefighting Foams (AFFF/AR-AFFF): A key ingredient in aqueous film-forming foams, providing rapid film formation and fuel resistance for Class B fires.
• Oil & Water Repellent Finishes: Imparts durable stain and liquid repellency to textiles, carpets, leather, and paper products.
• Specialty Coatings and Inks: Used as a leveling and wetting agent to improve substrate coverage and surface properties in high-performance fluoropolymer coatings.
• Electroplating and Metal Treatment: Acts as a mist suppressant and wetting agent in chromium plating and other metal finishing baths.
• Enhanced Oil Recovery (EOR): Functions as a surfactant to reduce interfacial tension in challenging reservoir conditions.
• Industrial Cleaners and Etchants: Provides superior wetting and penetration in acidic or alkaline cleaning formulations.
