Stainless steel is resistant to rust and is used for various applications. Here, we will introduce methods to impart insulation properties to stainless steel.
■Corrosion and Insulation of Stainless Steel Stainless steel is known for its resistance to rust, but it can experience galvanic corrosion between dissimilar metals. By coating it with a highly insulating resin to eliminate electrical contact, galvanic corrosion can be prevented. ■Highly Insulating Resins In general, plastics (resins) do not conduct electricity. Among them, resins such as fluororesin and polyimide are particularly excellent in electrical insulation and heat resistance, making them suitable for various applications. ■Cautions for Insulating Surface Treatments By insulating the surface of stainless steel with coatings like fluororesin, it is possible to maintain a state where electricity does not flow through the stainless steel surface. However, such coatings may require high-temperature curing and must be free of pinholes. Therefore, considerations regarding the design of the base material (component) and film thickness are necessary, and it is appropriate to consult a specialized contractor. *For information on the electrical properties of fluororesins, please click "PDF Download" or feel free to contact us.
