Abstract:
A method of applying an electrically conductive carbon coating to a non-conductive surface, comprising the following, in any operative order:A. providing a substrate having at least one non-conductive surface portion;B. contacting at least said nonconductive surface portion with a conditioning agent comprising an amount of a cationic substantive conditioner effective to deposit a film of said conditioner on said nonconductive surface portion, thereby forming a conditioned surface; andC. contacting said conditioned surface with a carbon dispersion comprising:i. electrically conductive carbon having a mean particle size no greater than about 50 microns, andii. a water dispersible binding agent to form a substantially continuous, electrically conductive carbon coating on said conditioned surface;wherein said carbon and said binding agent are present in amounts effective to provide an electrically conductive coating when said dispersion is applied to said conditioned surface.
