Description

Diammonium 4,4,5,5,6,6,7,7,8,8,9,9,10,10,11,11,12,12,13,13,14,14,15,15,16,16,17,17,18,19,19,19-Dotriacontafluoro-2-Hydroxy-18-(Trifluoromethyl)Nonadecyl Phosphate is a highly fluorinated phosphate ester salt designed to impart exceptional surface-modifying properties. This specialty chemical is engineered to deliver superior performance in demanding environments where standard surfactants fail, offering outstanding chemical and thermal stability. It is a critical raw material for advanced material scientists and formulators in industries requiring high-performance surface treatments and functional additives.

Application

• Fluorinated Surfactants & Leveling Agents: A key intermediate for synthesizing high-performance, low-surface-tension surfactants used in coatings, inks, and electronic materials.
• Firefighting Foams (AFFF): Used in the formulation of aqueous film-forming foams (AFFF) for combating flammable liquid fires, where its fluorinated chain provides rapid film formation and fuel suppression.
• Specialty Polymer Additives: Acts as a monomer or additive to introduce fluorinated phosphate groups into polymers, enhancing surface properties like oil and water repellency, and anti-fog characteristics.
• Lithium-Ion Battery Electrolytes: Potential use as a high-stability electrolyte additive or binder component to improve interfacial stability and cycle life in advanced battery systems.
• Textile & Leather Finishing: Imparts durable water, oil, and stain repellency to fabrics and leather goods without compromising breathability.
• Metalworking Fluids & Anti-Corrosion Coatings: Functions as a high-performance wetting agent and corrosion inhibitor in challenging metal processing and protective coating applications.

Quality Control

Our production of this specialty fluorochemical adheres to a strict quality management system. Every batch is analyzed using advanced techniques including NMR (19F, 1H, 31P) and HPLC to confirm structural identity, purity, and consistency. We provide comprehensive Certificates of Analysis (COA) with each shipment, detailing key parameters such as assay, moisture content, and ionic composition. Our quality commitment ensures material traceability and reliability for your critical applications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). This material is hygroscopic (moisture-sensitive) and must be kept under dry conditions to prevent hydrolysis and caking. Keep away from strong alkalis and incompatible materials.
