Description

Diammonium 4,4,5,5,6,6,7,7,8,8,9,9,10,10,11,11,12,12,13,13,14,14,15,15,15-pentacosafluoro-2-hydroxypentadecyl phosphate is a highly fluorinated phosphate ester salt, a specialized organofluorine compound valued for its unique combination of hydrophobicity, oleophobicity, and surfactant properties. This chemical is critical for applications requiring durable, low-surface-energy coatings and exceptional resistance to water, oils, and chemicals. It is primarily utilized by advanced material scientists and formulators in the textile, electronics, and high-performance coatings industries to impart stain, soil, and water repellency to surfaces and fabrics.

Application

• Textile Finishing Agent: As a key ingredient in durable water repellent (DWR) and stain-release finishes for technical apparel, outdoor gear, and upholstery fabrics.
• Surface Modifier for Electronics: Used to create hydrophobic and anti-fingerprint coatings on touchscreens, optical lenses, and electronic components.
• Paper and Packaging Treatment: Imparts grease and moisture resistance to specialty papers, food packaging, and cardboard.
• Fluorinated Surfactant/Additive: Acts as a wetting agent, leveling agent, or emulsifier in fluoropolymer dispersions and high-performance coating formulations.
• Firefighting Foam Component (Legacy Formulations): Historically used in some aqueous film-forming foam (AFFF) formulations. Note: Regulatory scrutiny on PFAS chemicals is intense; verify current compliance for this application.
• Stone and Masonry Protectant: Provides long-lasting water and oil repellency to natural stone, concrete, and brick.

Quality Control

Our production of this fluorinated phosphate ester adheres to strict quality management protocols. Each batch is analyzed to ensure consistent chemical composition, purity, and performance characteristics. A comprehensive Certificate of Analysis (COA) is provided with every shipment, detailing key parameters such as assay, fluoride content, and pH. We support our clients' regulatory needs with documentation traceability.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). This material is hygroscopic (moisture-sensitive); the container must be kept tightly sealed after opening to prevent degradation due to moisture absorption. Keep away from strong acids and strong oxidizing agents.
