A conductive composition includes a conductive metal, a first resin component, and a second resin component, which is an isocyanate component, that is reactive with the first resin component. A metal oxide and a lubricant are present as impurities on a surface of the metal. The second resin component is blocked at a first temperature and unblocked at a second temperature greater than the first temperature to produce fist and second fluxing agents. The first fluxing agent reacts with the lubricant to partially remove the oxide and the lubricant from the surface of the metal. The removal, or cleansing, of the oxide and the lubricant from the metal increases a conductivity of the composition. A method deposits a trace of the composition on a substrate and heats the composition to the second temperature to cause the second resin component to unblock. |
