Description

Potassium Perfluoroheptanoate is a high-performance fluorinated surfactant and anionic perfluorinated carboxylate salt. This compound is valued for its exceptional surface activity, chemical and thermal stability, and oleophobic/hydrophobic properties derived from its perfluorinated carbon chain. It is a critical material for industries requiring advanced surface modification, emulsification, and dispersion in demanding environments. Key sectors utilizing this specialty chemical include electronics manufacturing, firefighting, polymer processing, and specialty coatings.

Application

• Aqueous Film-Forming Foam (AFFF) Concentrates: A key ingredient in Class B firefighting foams for hydrocarbon fuel fires, where it enables rapid film formation and vapor suppression.
• Electronics and Semiconductor Processing: Used as a surfactant and wetting agent in photoresist developers, etchants, and cleaning solutions for precise micro-fabrication.
• Polymerization (Emulsion Polymerization): Serves as an effective emulsifier and surfactant in the production of fluoropolymers like PTFE (Teflon™) and other high-performance plastics.
• Specialty Coatings and Surface Treatments: Imparts oil, water, and stain repellency to textiles, carpets, paper, and leather.
• Industrial Cleaners and Degreasers: Enhances the wetting and penetrating power of formulations designed to remove oils, greases, and fluorinated contaminants.
• Chemical Intermediate: Used in the synthesis of other perfluorinated compounds and surface-active agents for specialized applications.

Storage

Preserve in a tightly closed container, protected from light. This material is hygroscopic (moisture-sensitive) and must be stored in a cool, dry, and well-ventilated area. Recommended storage temperature is between 15°C and 25°C. Keep the container tightly sealed when not in use to prevent absorption of atmospheric moisture and CO2. Store away from strong acids and strong oxidizing agents.
