Description

1H,1H,2H,3H,3H-Perfluoroundecan-1,2-Diol is a specialized fluorinated diol characterized by a long perfluorinated carbon chain terminated with a hydroxyl group, offering a unique combination of hydrophobicity, oleophobicity, and chemical resistance. This compound is highly valued for its ability to impart exceptional surface-modifying properties, including low surface energy and high thermal stability. It is a critical intermediate for advanced material scientists and formulators in industries such as high-performance coatings, specialty polymers, and surface treatments where durable water and oil repellency are paramount.

Application

• As a key monomer or additive in the synthesis of high-performance, fluorinated polymers and resins for coatings with exceptional chemical and stain resistance.
• As a surface-modifying agent to create superhydrophobic and oleophobic coatings for textiles, electronics, and optical components.
• In the formulation of specialized release agents and mold lubricants for demanding industrial and manufacturing processes.
• As a building block for fluorinated surfactants and leveling agents used in high-value coating and film applications.
• In research and development of advanced materials for microelectronics and semiconductor fabrication where precise surface properties are required.
• For modifying surface properties of fillers and pigments to improve dispersion and performance in composite materials.
