Conductive welding primer on fabric


I saw the discussions about conductive fabric with the links to and others. I'd like to get anyone's thoughts about painting a schematic on cloth using welding conductive primer such as SEM copper weld-through primer (Product Code #: SEM40783) that I found at Since that works for welding, would it work for soldering wires to it?

Best Answer

There are conductive glues and silicones available like this one. You could bond wires (and components) to fabric with a conductive glue and use any other paintable conductive material that remains flexible after drying to lay out a circuit. The printing/painting resolution probably wouldn't be great so circuit complexity and density would be constrained, but I see no obvious reason why it couldn't work.
