Substrate with electrically conductive coating as well as method of preparing a substrate with an electrically conductive coating

摘要

A method for producing a temperature-resistant, electrically conductive coating on a substrate is provided. The method includes at least the steps of providing a binding agent, the binding agent having an inorganically crosslinked, SiO2-containing binding-agent matrix; producing a dispersion of an electrically conductive pigment in the binding agent by mechanical convection, wherein the fraction of electrically conductive pigment amounts to 10 to 40 wt. %, and carbon is used as the electrically conductive pigment; partial, structured printing of the coating material obtained by dispersion onto the substrate; and drying the obtained coating at temperatures in the range of 20 to 250° C. Also provided are preparations for producing an electrically conductive coating on a substrate as well as substrates provided with electrically conductive coatings.
