Fluorocarbon coatings have revolutionized the way we protect and preserve materials, especially in harsh environments. The first "fluorocarbon coating" with a lifespan of over 100 years was actually developed in 1938 by DuPont under the name Teflon. This coating, made from polytetrafluoroethylene (PTFE) or its copolymers like polyperfluoropropylene (FEP), is renowned for its exceptional heat resistance (up to 260°C), low-temperature tolerance (-200°C), self-lubricating properties, and chemical stability. Often referred to as "the corrosion-resistant, non-stick Teflon," these materials were initially used in specialized applications such as non-stick cookware, medical equipment, and aerospace due to their unique performance characteristics. However, fluorocarbon coatings were not immediately adopted in the construction industry. Their high melting point and poor pigment dispersion limited their use to niche markets. It wasn't until 1965 that Pennwalt introduced a fluorocarbon coating based on polyvinylidene fluoride (PVDF), known commercially as Kynar 500, specifically designed for building applications. Since then, PVDF-based fluorocarbon coatings have been widely used to protect thousands of buildings worldwide. Despite being a baked coating with a lower curing temperature (around 230°C) compared to PTFE, they still require factory processing, which limits their on-site application and broader adoption in the construction sector. A major breakthrough came in 1982 when Japan’s Asahi Glass Co., Ltd. developed a new type of fluororesin called FEVE (fluoroolefin-vinyl ether copolymer). This material could be cured at room temperature and dissolved in common solvents like aromatic hydrocarbons, lipids, and ketones. This innovation allowed for the direct application of fluorocarbon coatings on construction sites, eliminating the need for high-temperature baking. As a result, the versatility and range of fluorocarbon coatings expanded significantly, making them an ideal choice for long-term protection in various architectural and industrial settings.
