Description

Sodium 3-[[3-(Dimethylamino)Propyl][(Tridecafluorohexyl)Sulphonyl]Amino]-2-Hydroxypropanesulphonate is a specialized fluorinated anionic surfactant with a unique zwitterionic-like structure, offering exceptional surface activity and stability. This compound is engineered to deliver superior wetting, emulsification, and leveling properties in demanding, high-performance formulations. It is a critical ingredient for industries requiring advanced surface modification, particularly where compatibility with fluorinated systems and resistance to harsh environments are paramount.

Application

• Fluoropolymer Processing: Acts as a key surfactant and emulsifier in the polymerization of PTFE (Teflon®), FEP, and PFA, ensuring stable dispersion and particle size control.
• Firefighting Foams (AFFF - Aqueous Film-Forming Foam): Serves as a critical fluorosurfactant component to create a fast-spreading, fuel-sealing film for Class B hydrocarbon fuel fires.
• High-Performance Coatings & Inks: Provides excellent wetting, flow, and leveling in solvent-based and water-based coatings, especially for non-stick and release coatings.
• Textile & Leather Treatment: Imparts durable oil, water, and stain repellency to fabrics, carpets, and leather goods.
• Electronics & Semiconductor: Used in photoresist formulations and as a surfactant in etching and cleaning solutions for precise surface preparation.
• Specialty Cleaning & Polishing: Enhances the cleaning efficacy of industrial and institutional cleaners for hard surfaces, glass, and metals.

Quality Control

Our production of Sodium 3-[[3-(Dimethylamino)Propyl][(Tridecafluorohexyl)Sulphonyl]Amino]-2-Hydroxypropanesulphonate adheres to a strict quality management system. Every batch undergoes rigorous analytical testing, including HPLC for purity and assay, NMR for structural confirmation, and Karl Fischer titration for moisture content, to ensure consistent performance and high purity. Comprehensive Certificates of Analysis (COA) are provided with each shipment, and we support compliance with relevant global regulatory frameworks.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). This material is hygroscopic (moisture-sensitive); the container must be kept tightly sealed after opening to prevent absorption of atmospheric moisture, which can affect product performance.
