Description

Bis[Trimethyl-3-[[(Undecafluoropentyl)Sulphonyl]Amino]Propylammonium] Sulphate is a specialized fluorinated quaternary ammonium salt, valued for its unique combination of cationic charge and perfluorinated alkyl chain. This structure provides powerful surfactant properties with exceptional chemical and thermal stability, making it a critical performance additive. It is primarily used in industries requiring advanced surface modification, such as high-performance coatings, firefighting foams, and specialty polymer processing.

Application

• As a key fluorosurfactant in aqueous film-forming foams (AFFF) for Class B firefighting.
• As a surface tension modifier and leveling agent in high-performance fluoropolymer coatings and paints.
• As an emulsifier and stabilizer in the synthesis of fluorinated polymers and copolymers.
• As an additive to enhance wetting and spreading in electronic chemicals and precision cleaning formulations.
• In textile treatment to impart oil, water, and stain repellency to fabrics.
• As a component in specialty paper coatings and release agents.
