What is corrosion protection? Explanation of methods to enhance corrosion resistance [Materials available].
Teflon coating
Is it enough to prevent just one element of corrosion for corrosion protection?
Corrosion prevention refers to methods used to prevent corrosion. Metal corrosion is a state in which the appearance and function of an object are compromised due to chemical and biological actions. Iron is generally cited as a metal material that is prone to corrosion. These metals can undergo rust and corrosion as a result of factors that cause corrosion, such as oxygen, sulfur, nitrogen, and water vapor present in the atmosphere, combined with the inherent properties of the metal, impurities, and electrochemical reactions. ■ The three main elements of corrosion: - The flow of electricity - The presence of water - The presence of oxides To enhance corrosion resistance, it is important to prevent one of these three elements. ■ Corrosion prevention using Teflon fluoropolymer 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 excellent chemical resistance but also due to its insulating properties, water repellency, and weather resistance. Additionally, advancements in processing technology have made it possible to select materials and shapes suited to specific applications. *For details on coatings and linings that enhance corrosion resistance, please download the materials for confirmation.

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 there is no leaching of ions. ●Coating technology without pinholes By applying a Teflon coating without electrical pinholes to substrates with shapes that cannot be lined with sheets or rotational molding, 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 significantly reduces blister formation and offers a lifespan over ten times longer, with a maximum film thickness of up to 2000μm possible due to our unique processing technology (depending on substrate conditions). With this technology, we provide coatings with superior corrosion resistance.
