Used primarily in the synthesis of fluorinated polymers, this chemical imparts exceptional water and oil repellency to surfaces. It is commonly employed in coatings, textiles, and electronic materials to enhance durability and resistance to environmental factors. Its fluorinated chain improves thermal stability and chemical resistance in polymer matrices. Frequently found in specialty applications such as anti-fouling coatings, release agents, and hydrophobic layers in optical and electronic devices. Also utilized in surface modification to reduce surface energy, making materials less prone to staining and easier to clean.
