Description

Potassium Heptadecafluoroisooctanesulphonate is a high-performance fluorinated anionic surfactant and electrolyte salt. This compound is valued for its exceptional chemical and thermal stability, low surface tension, and unique hydrophobic/oleophobic properties derived from its perfluorinated carbon chain. It is primarily utilized in advanced material science and specialty chemical manufacturing where superior surface activity and stability under harsh conditions are required. Key industries include electronics, coatings, and high-performance polymer production.

Application

• Electrolyte Additive for Lithium-Ion Batteries: Enhances electrolyte stability and forms a stable solid-electrolyte interphase (SEI) layer on high-voltage cathodes.
• Fluorinated Surfactant for Coatings and Inks: Provides excellent wetting, leveling, and anti-foaming properties in fluoropolymer coatings and specialty inks.
• Monomer for Fluorinated Polymers: Serves as a building block or comonomer in the synthesis of ionomers and other specialty fluoropolymers.
• Etching and Plating Bath Additive: Used in metal surface treatment and semiconductor manufacturing processes.
• Fire-Fighting Foam Concentrate (Legacy/Historical): A component in some aqueous film-forming foams (AFFF) for liquid fuel fires.
• Research & Development: Employed in academic and industrial R&D for studying fluorinated systems and novel material properties.
