Used as a surface treatment agent to provide water, oil, and soil repellency on various substrates such as glass, metal, and plastics. Commonly applied in coatings and sealants to enhance durability and resistance to environmental factors. Frequently utilized in the production of anti-stain and easy-to-clean surfaces for architectural glass, optical devices, and electronic components. Also employed in textile finishing to impart durable water repellency without altering fabric hand feel. Its fluorinated chain offers superior performance in low-surface-energy applications, making it effective in release coatings and anti-fouling systems.
