Description

1-Propanaminium, n-(Carboxymethyl)-3-(3,3,4,4,5,5,6,6,7,7,8,8,9,9,10,10,10-Heptadecafluorodecyl)Sulfonylamino-N,n-Dimethyl-, Inner Salt is a high-performance fluorinated surfactant and zwitterionic compound, engineered to deliver exceptional surface activity and stability in demanding environments. Its unique structure, featuring a long perfluorinated chain, provides outstanding oil and water repellency, low surface tension, and compatibility with various chemical systems. This product is essential for manufacturers in the coatings, fire-fighting foam, and specialty chemical industries seeking to enhance product performance with advanced fluorochemical technology.

Application

• Fluorinated Fire-Fighting Foams (AFFF/AR-AFFF): A key ingredient in aqueous film-forming foams, providing rapid film formation and superior fuel sealant properties for Class B fires.
• Specialty Coatings and Inks: Imparts excellent leveling, wetting, and anti-cratering properties in high-performance fluoropolymer coatings, paints, and printing inks.
• Oil and Water Repellent Treatments: Used to create durable, stain-resistant finishes for textiles, leather, carpets, and paper products.
• Electronics and Semiconductor Processing: Serves as a surfactant in photoresist developers and cleaning formulations where low surface tension and high purity are critical.
• Polymerization Aid: Acts as an emulsifier or surfactant in the emulsion polymerization of fluorinated monomers.
• Metal Plating and Surface Treatment: Enhances wetting and reduces surface defects in electroplating baths and metal finishing processes.

Quality Control

Every batch of our fluorinated surfactants is produced under strict quality management systems to ensure consistency and performance. We provide comprehensive Certificates of Analysis (COA) with each shipment, detailing key parameters such as assay, ionic content, and critical impurities. Our manufacturing adheres to ISO 9001 standards, and we support our global customers with documentation for regulatory compliance, including REACH and regional chemical inventories.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at a controlled room temperature (15-25°C). This material is hygroscopic (moisture-sensitive); ensure containers are kept tightly sealed when not in use to prevent absorption of atmospheric moisture, which may affect performance.
