Description

Potassium Heptadecafluoro-1-Octanesulfonate is a high-purity perfluorinated sulfonate salt, a key member of the perfluoroalkyl sulfonate (PFAS) chemical family. This compound is valued for its exceptional chemical and thermal stability, low surface energy, and surfactant properties, making it a critical performance additive in advanced materials. It is primarily sought by manufacturers in the electronics, specialty polymers, and surface treatment industries for applications requiring superior hydrophobic, oleophobic, and anti-static characteristics.

Application

• Electronics Manufacturing: As a critical component in photoresist formulations and edge bead removers for semiconductor and display fabrication.
• Specialty Polymers & Coatings: Used as a surfactant and additive to impart oil, water, and stain resistance to high-performance fluoropolymers and surface coatings.
• Fire-Fighting Foams (AFFF): Serves as a key ingredient in some aqueous film-forming foams for combating flammable liquid fires.
• Analytical Chemistry & Biotechnology: Employed as a mobile phase additive in liquid chromatography (LC-MS) to improve ionization efficiency and peak shape.
• Metal Plating & Surface Treatment: Acts as a wetting agent and mist suppressant in chrome plating and other metal finishing processes.
• Lithium-Ion Battery Electrolytes: Investigated as a stabilizing additive to enhance the performance and safety of electrolyte formulations.

Quality Control

Our Potassium Heptadecafluoro-1-Octanesulfonate is manufactured under strict quality management systems. Each batch is analyzed to ensure it meets precise specifications for purity and performance, with testing typically including assay (HPLC), identification (IR, NMR), and impurity profiling. A comprehensive Certificate of Analysis (COA) detailing all test results is provided with every shipment to ensure traceability and compliance for our global B2B customers.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). Due to its hygroscopic nature, the container must be kept tightly sealed to prevent moisture absorption, which can affect product performance. Keep away from strong acids and strong bases.
