Teflon Coating: "What is the method to enhance corrosion resistance with Teflon resin?"
Teflon coating
What is the method to protect metal from corrosion with Teflon coating? Can corrosion be prevented by just preventing one single factor?
■Corrosion of Metals Corrosion refers to a state in which the appearance or function of an object is impaired due to chemical or biological actions. Iron is generally cited as a metal material that is prone to corrosion. These metals can develop rust and corrosion as a result of factors that cause corrosion, such as oxygen, sulfur, nitrogen, and water vapor in the atmosphere, along with the inherent properties of the metal, impurities, and electrochemical reactions. ■Three Elements of Corrosion - The flow of electricity - The presence of water - The presence of oxidants By preventing any one of these elements through coating, metal corrosion can be prevented. ■Prevention of Metal Corrosion by Teflon Coating Teflon fluoropolymer is widely used as a corrosion-resistant material due to its exceptional chemical resistance among resins. This is not only because of its superior chemical resistance but also due to its properties such as heat resistance, cold resistance, weather resistance, non-stick properties, purity, low friction, and processability. It can be said that advancements in both the development of Teflon resin varieties and processing technologies have allowed for the selection of materials and shapes suitable for various applications. *For more details on Teflon coating, please refer to the catalog or contact us.*

basic information
■Excellent corrosion resistance Teflon coating ●Chemical resistance of Teflon resin Teflon resin is chemically stable, so it is not affected by most acids and alkalis, and ions do not dissolve and leak out. ●Coating technology without pinholes By applying a Teflon coating without electrical pinholes to substrates with shapes that cannot be lined or rotationally molded, we protect against highly corrosive liquids and gases such as acids and alkalis, and prevent the leaching of metal ions from the substrate. ●Prevents liquid penetration and has excellent blister resistance Compared to standard Teflon coatings, our MY lining reduces the occurrence of blisters and offers a lifespan that is expected to be more than ten times longer. Our unique processing technology allows for a film thickness of up to 2000μm (depending on substrate conditions). With this technology, we provide coatings with excellent corrosion resistance.
