Description

Potassium 3,3,4,4,5,5,6,6,7,7,8,8,8-tridecafluorooctanesulphonate is a high-performance fluorinated anionic surfactant and electrolyte salt, distinguished by its exceptional chemical and thermal stability imparted by the perfluorinated alkyl chain. This compound is critical for applications requiring superior surface activity, hydrophobicity, and oleophobicity in demanding environments. It serves as a key raw material for advanced material science, electronics, and specialty chemical synthesis, where its unique properties enable enhanced performance and reliability.

Application

• Fluorinated Surfactant & Leveling Agent: Used in high-performance coatings, paints, and fire-fighting foams to improve wetting, spreading, and film formation.
• Electrolyte Additive: Employed in lithium-ion and other advanced battery systems to enhance electrolyte stability and electrode interface properties.
• Polymerization Aid (Emulsifier/Surfactant): Acts as a specialty emulsifier in the emulsion polymerization of fluorinated monomers (e.g., PTFE, PVDF).
• Textile & Leather Treatment: Imparts durable water, oil, and stain repellency to fabrics and leather goods.
• Electronic Chemicals: Used in photoresist formulations and as an additive in electronics plating baths for improved uniformity.
• Pharmaceutical & Agrochemical Intermediates: Serves as a building block for synthesizing molecules with enhanced bioavailability and environmental persistence.
• Analytical Chemistry: Functions as a mobile phase additive or ion-pairing agent in HPLC for separating complex mixtures.
