  • Method for applying a coating that acts as an electrolytic barrier and a cathodic corrosion prevention system
    Patent number: 6627117
    Abstract: A coating system for ferrous and nonferrous metal substrates that provides cathodic protection from corrosion by coating with inherently conductive polymers and sacrificial anodic metal particles. The coating system is formed by a process that includes premixing of the inherently conductive polymer with the anodic metal particles to form a inherently conductive polymer/metal particle complex.
