Used primarily in the synthesis of fluorinated polymers, this chemical imparts exceptional water and oil repellency to surfaces. It is widely applied in coatings and finishes for textiles, paper, and electronic materials to enhance stain resistance and durability. Its fluorinated chain improves thermal and chemical stability in polymer matrices, making it suitable for high-performance protective coatings. It is also utilized in specialty adhesives and sealants where low surface energy and moisture resistance are critical.
