Used as a surface treatment agent to provide water and oil repellency on various substrates. Commonly applied in coatings and finishes for textiles, paper, and leather to enhance stain resistance and durability. Also utilized in electronic and optical materials to improve moisture resistance and surface compatibility. Its fluorinated chain offers low surface energy, making it effective in anti-fouling and release coatings. Suitable for use in formulations requiring long-term stability under harsh environmental conditions.
