Description

Ammonium Nonadecafluorodecanoate is the ammonium salt of a highly fluorinated carboxylic acid, representing a key perfluorinated surfactant. This compound is valued for its exceptional surface activity, thermal stability, and chemical inertness, derived from its long perfluoroalkyl chain. It is primarily sought by industries requiring advanced performance materials, such as fluoropolymer processing, fire-fighting foams, and specialty coatings.

Application

• As a critical processing aid and surfactant in the emulsion polymerization of fluoropolymers like PTFE (Polytetrafluoroethylene) and FEP (Fluorinated Ethylene Propylene).
• As a key ingredient in aqueous film-forming foam (AFFF) concentrates for Class B fire suppression, where it enables rapid film formation and fuel sealing.
• As a leveling and wetting agent in high-performance coatings, inks, and adhesives to improve surface coverage and uniformity.
• As a surface modifier for textiles, leather, and paper to impart oil, water, and stain repellency.
• In the formulation of specialty cleaning products and etchants for the electronics and semiconductor industries.
• As a dispersing agent for pigments and fillers in demanding chemical environments.

Quality Control

Our Ammonium Nonadecafluorodecanoate is manufactured under a strict quality management system. Each batch undergoes comprehensive analytical testing to ensure it meets precise specifications for purity, ionic content, and performance characteristics. Certificates of Analysis (COA) documenting key parameters are provided to guarantee traceability and batch-to-batch consistency for your critical applications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at room temperature (15-25°C). This material is hygroscopic (moisture-sensitive); ensure containers are sealed immediately after use to prevent absorption of atmospheric moisture, which can affect performance.
