Description

(3,3,4,4,5,5,6,6,7,7,8,8,9,9,10,10,10-Heptadecafluorodec-1-Yl)Phosphonic Acid is a high-value, long-chain perfluorinated phosphonic acid derivative that imparts unique surface-modifying properties. This compound is critical for applications requiring extreme hydrophobicity, oleophobicity, and chemical resistance due to its highly fluorinated alkyl chain. It is primarily sought by manufacturers in the advanced materials, electronics, and specialty coatings sectors for creating low-surface-energy surfaces.

Application

• Surface Modification Agent: Used to create ultra-hydrophobic and oleophobic coatings on textiles, metals, glass, and polymers.
• Anti-fouling Coatings: A key intermediate in formulations for marine paints and coatings that resist biological adhesion.
• Electronics Manufacturing: Employed as a surface treatment for semiconductors and electronic components to provide moisture resistance and improve performance.
• Lithography and Photoresists: Serves as a component in advanced photoresist formulations for micro- and nano-fabrication processes.
• Biomedical Interfaces: Used to modify the surface of medical devices and implants to enhance biocompatibility and reduce protein adsorption.
• Fluoropolymer Synthesis: Acts as a functional monomer or additive in the production of specialized fluoropolymers with tailored surface properties.

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 an inert atmosphere (e.g., nitrogen or argon) in its original packaging to prevent degradation. Keep away from strong bases and oxidizing agents.
