Description

Ammonium Octadecafluoro-9-(Trifluoromethyl)Decanoate is a high-performance fluorinated surfactant and chemical intermediate, distinguished by its unique perfluorinated alkyl chain terminated with a trifluoromethyl group. This structure provides exceptional surface activity, chemical inertness, and thermal stability, making it a critical component for demanding industrial applications. It is primarily sought after by manufacturers in the electronics, specialty polymers, and advanced materials sectors for its ability to impart oil, water, and stain repellency, as well as to modify surface energy.

Application

• Fluoropolymer Manufacturing: Acts as a polymerization aid, surfactant, or processing additive in the production of PTFE, FEP, and PFA resins.
• Electronics & Semiconductor: Used in photoresist formulations, as a surfactant in etching and cleaning solutions, and for surface treatment of electronic components.
• Fire-Fighting Foams (AFFF): Serves as a key fluorosurfactant component in aqueous film-forming foams for combating hydrocarbon fuel fires.
• Textile & Fiber Treatment: Imparts durable water, oil, and stain repellency to technical textiles, outdoor apparel, and carpets.
• Coatings & Surface Modifiers: Used to create low-surface-energy, anti-fouling, and release coatings for various substrates.
• Specialty Chemicals Synthesis: A versatile building block for synthesizing more complex fluorinated compounds and pharmaceuticals.
