Used as a surface treatment agent to create highly hydrophobic and oleophobic coatings. Commonly applied in the manufacturing of water-repellent and anti-fouling films for optical devices, electronic components, and medical instruments. Its fluorinated chains provide excellent chemical resistance and low surface energy, making it ideal for self-cleaning surfaces and protective coatings in harsh environments. Also utilized in microfluidics and semiconductor fabrication to modify surface properties and control wetting behavior.
