Used as a surface treatment agent to provide water and oil repellency on various substrates such as glass, metals, and polymers. Commonly applied in coatings and thin films for optical devices, where it enhances durability and prevents fogging or staining. Also utilized in microfluidics and lab-on-a-chip systems to create hydrophobic channels that control fluid behavior. Its fluorinated chain offers strong resistance to heat, chemicals, and environmental degradation, making it suitable for harsh environment applications. Often employed in self-assembled monolayers (SAMs) for research and industrial surfaces requiring precise wetting properties.
