Used in the synthesis of fluorinated polymers that exhibit excellent water and oil repellency, making them ideal for coatings in optical fibers, electronic devices, and medical equipment. Its incorporation into copolymers enhances surface properties such as low friction, chemical resistance, and thermal stability. Commonly applied in specialty coatings requiring durability under harsh environments, including aerospace and semiconductor manufacturing. Also utilized in developing hydrophobic and oleophobic thin films for anti-fouling and anti-sticking surfaces.
