Description

[[4-[(Heptadecafluorononenyl)Oxy]Phenyl]Methyl]-Phosphonic Acid is a high-value fluorinated phosphonic acid derivative, distinguished by its unique perfluorinated side chain. This structural combination imparts exceptional surface-active properties, including high chemical and thermal stability, low surface energy, and excellent oleophobicity. It is a critical intermediate for advanced material scientists and formulators in industries requiring durable, low-surface-tension coatings and functional additives.

Application

• Surface Modification Agent: Key component for creating ultra-hydrophobic and oleophobic coatings on textiles, metals, glass, and polymers.
• Fluorinated Surfactant Intermediate: Used in the synthesis of high-performance surfactants for demanding applications in fire-fighting foams, electronics cleaning, and specialty polymerizations.
• Additive for Specialty Polymers: Incorporated into fluoropolymers and other high-performance plastics to enhance surface properties, reduce friction, and improve chemical resistance.
• Anti-fog and Anti-reflective Coatings: Serves as a building block for coatings used in optical lenses, displays, and military optics.
• Adhesion Promoter: Improves the bonding interface between fluorinated materials and substrates in composite manufacturing.
• Lithography and Semiconductor Processing: Potential use as a resist material or surface treatment agent in microelectronics fabrication due to its etch resistance.
