Description

Ammonium Tetradecafluoro-7-(Trifluoromethyl)Octanoate is a highly fluorinated ammonium carboxylate salt, a key building block for advanced fluorinated surfactants and surface modifiers. Its unique perfluorinated alkyl chain structure provides exceptional chemical and thermal stability, along with powerful surface tension reduction and hydrophobic/oleophobic properties. This compound is essential for formulators and manufacturers in the electronics, coatings, and specialty polymer industries seeking to enhance performance characteristics such as water and oil repellency, leveling, and anti-foaming.

Application

• Fluorinated Surfactant Intermediate: Primary raw material for synthesizing high-performance anionic and nonionic fluorosurfactants used in demanding industrial applications.
• Fire-Fighting Foams (AFFF): A key component in the formulation of aqueous film-forming foams (AFFF) for combating flammable liquid fires, providing rapid film formation and vapor suppression.
• Electronics & Semiconductor Processing: Used in photoresist developers, etching baths, and cleaning solutions to improve wetting, reduce surface defects, and ensure uniform coating.
• Coatings & Inks: Imparts superior leveling, flow, and substrate wetting properties to high-performance paints, varnishes, and printing inks, while also adding stain and water resistance.
• Oil & Gas Industry: Functions as a mist suppressant and anti-foaming agent in acidizing fluids and other well stimulation treatments.
• Polymer Modification: Acts as a comonomer or additive to introduce fluorinated segments into polymers, enhancing their chemical resistance and lowering surface energy.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). This material is hygroscopic (moisture-sensitive). Keep the container tightly sealed when not in use to prevent absorption of atmospheric moisture, which can affect product quality and handling properties. Keep away from strong acids and strong bases.
