Abstract
A corrosion detection product is a coating including a film forming material and a complexing agent, the complexing agent forming a complex when it comes into contact with a corrosion byproduct produced by corrosion of a substrate on which the coating is applied, the complex being detectably different from the complexing agent when the coating is exposed to radiation in order to detect the corrosion, the complexing agent being immobilized in the coating to reduce leaching of the complexing agent or the complex from the coating.
