Description

Potassium n-[4,4,5,5,6,6,7,7,8,8,9,9,10,11,11,11-Hexadecafluoro-2-Hydroxy-10-(Trifluoromethyl)Undecyl]-n-Methylaminoacetate is a highly fluorinated, specialty potassium salt designed for advanced material science and surface engineering applications. This compound is valued for its ability to impart exceptional oil, water, and stain repellency, as well as low surface energy properties to various substrates. It is a critical intermediate and functional additive for manufacturers in the fluorochemical, textile, and high-performance coatings industries seeking to develop next-generation, durable surface treatments.

Application

• Fluorinated Surfactant & Leveling Agent: Key component in high-performance fluoropolymer coatings and paints to enhance wetting, leveling, and film formation.
• Textile & Fiber Treatment: Used to create durable water and oil repellent (DWR/DOR) finishes on technical fabrics, outdoor gear, and protective clothing.
• Paper & Packaging Coatings: Imparts grease resistance and barrier properties to food packaging and specialty papers.
• Fire-Fighting Foam Concentrates (Legacy/Historical Formulations): Served as a fluorosurfactant in certain aqueous film-forming foam (AFFF) formulations for hydrocarbon fuel fires. (Note: Regulations on PFAS are evolving globally).
• Surface Modifier for Polymers: Enhances the surface properties of plastics and elastomers, improving chemical resistance and reducing friction.
• Specialty Chemical Intermediate: Utilized in the synthesis of more complex fluorinated compounds for electronics and pharmaceuticals.

Quality Control

Our production of Potassium n-[4,4,5,5,6,6,7,7,8,8,9,9,10,11,11,11-Hexadecafluoro-2-Hydroxy-10-(Trifluoromethyl)Undecyl]-n-Methylaminoacetate adheres to a strict quality management system. Each batch is analyzed to ensure it meets precise chemical and physical specifications, including identity, purity, and impurity profiles. A comprehensive Certificate of Analysis (COA) detailing results from advanced analytical techniques (HPLC, NMR, KF titration) is provided with every shipment to guarantee consistency and support your quality assurance protocols.

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); keep the container tightly sealed to prevent absorption of atmospheric moisture. Isolate from strong acids and strong oxidizing agents.
