Ethylene Tetrafluoroethylene (ETFE) is a fluorine-based plastic known for its exceptional durability, chemical resistance, and high-temperature tolerance. Originally developed by DuPont in the 1970s, ETFE has found applications in various industries, including architecture, aerospace, and chemical processing, due to its unique properties. ETFE primers play a vital role in ensuring the durability and effectiveness of ETFE coatings. By enhancing adhesion, providing additional chemical resistance, and improving mechanical strength, these primers form the foundation for long-lasting protective coatings in a variety of demanding applications. Whether in architecture, chemical processing, aerospace, or electrical insulation, ETFE primers are essential for achieving optimal performance and longevity of ETFE-coated surfaces.
