Description

Ammonium Bis[3,3,4,4,5,5,6,6,7,7,8,8,9,9,10,10,11,11,12,12,13,13,14,14,15,16,16,16-Octacosafluoro-15-(Trifluoromethyl)Hexadecyl] Phosphate is a highly fluorinated ammonium phosphate ester surfactant. This compound is engineered to deliver exceptional surface tension reduction and oil and water repellency in demanding environments. It is a critical performance additive for industries requiring advanced fluorosurfactant properties, such as high-performance coatings, fire-fighting foams, and specialty chemical formulations. Its unique perfluorinated alkyl chain structure provides unparalleled stability and functionality.

Application

• Fluorosurfactant for Fire-Fighting Foams (AFFF/AR-AFFF): A key ingredient in aqueous film-forming foams, providing rapid spreading and vapor suppression for hydrocarbon fuel fires.
• Performance Additive for Coatings and Inks: Imparts superior leveling, wetting, and anti-cratering properties in high-solids, waterborne, and solvent-based coating systems.
• Oil and Water Repellent for Textiles and Leather: Used to create durable, stain-resistant finishes for technical textiles, outdoor apparel, and luxury leather goods.
• Additive for Polishing Slurries (CMP): Enhances surface wetting and particle dispersion in chemical mechanical planarization slurries for semiconductor manufacturing.
• Industrial Cleaner and Etchant Formulations: Improves wetting and penetration on low-energy surfaces in acidic or alkaline cleaning solutions for metals and electronics.
• Specialty Polymer Additive: Acts as a processing aid and surface modifier in fluoropolymers and high-performance engineering plastics.

Quality Control

Our production of Ammonium Bis[3,3,4,4,5,5,6,6,7,7,8,8,9,9,10,10,11,11,12,12,13,13,14,14,15,16,16,16-Octacosafluoro-15-(Trifluoromethyl)Hexadecyl] Phosphate adheres to a rigorous quality management system. Each batch is analyzed to ensure consistent chemical composition, purity, and performance characteristics. Key parameters such as active content, fluoride/strong alkali compatibility, and ionic impurities are strictly monitored. Certificates of Analysis (COA) documenting full specifications are provided with every shipment to ensure traceability and compliance for our global B2B clients.

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 moisture-sensitive (hygroscopic) and incompatible with strong acids and strong bases. Keep away from heat and ignition sources. For long-term storage, consider using desiccants and maintaining an inert atmosphere to preserve efficacy.
