Description

[3-[[(Heptadecafluorooctyl)Sulphonyl]Amino]Propyl]Trimethylammonium Hydrogen Sulphate is a high-value fluorinated quaternary ammonium salt, engineered to impart exceptional surface-active and oleophobic properties. This compound matters for its unique ability to lower surface tension dramatically and provide durable water and oil repellency, even at low concentrations. It is critically needed by formulators in the textile, coatings, and specialty chemical industries seeking to develop advanced stain-resistant, anti-fouling, and release applications.

Application

• As a key fluorosurfactant and leveling agent in high-performance fluoropolymer coatings and paints.
• For imparting durable water, oil, and stain repellency to textiles, carpets, and non-woven fabrics.
• As an additive in fire-fighting foams (historically for AFFF formulations) to enhance film-forming and spreading properties.
• In the formulation of specialty cleaning products and waxes where superior wetting and surface modification are required.
• As a surface modifier and antistatic agent in the production of specialty plastics and films.
• For research and development of novel materials in biomedical and electronic applications requiring fluorinated interfaces.
