Used primarily as a reactive diluent and crosslinking agent in fluoropolymer formulations, enhancing the durability and chemical resistance of coatings. It is employed in the synthesis of specialty fluoroelastomers and surface modifiers where improved hydrophobicity and oleophobicity are required. Its allyl functionality allows for efficient radical polymerization, making it suitable in curable resin systems for industrial and electronic coatings. Also utilized in the development of water- and oil-repellent treatments for textiles and membranes due to its long perfluorinated chain.
