Thin Acid Resistant Coating for Metal Device
We are trying to find a suitable coating for a cylinder-shaped metal device (diameter is around 6 cm) that is to be immersed constantly in a hypochlorous acid solution with a pH of around 5. This coating should be as thin as possible(if possible, less than 2 mm thick). Your response would be greatly appreciated.Aria Pezeshk

2 mm is quite thick for a coating, Aria. Have you given us the wrong units of measure? A plastisol coating of 2 mm thickness or less is often used as a tank lining or rack coating to prevent corrosion against powerful and diverse acids. If this is a one-time experiment, platers tape (similar to electricians tape, but heavier) might do.
