    Abstract: An electrically conductive paste providing low alpha particle emission is provided. A resin and conductive particles are mixed, and a curing agent is added. A solvent is subsequently added. The electrically conductive paste including a resin compound is formed by mixing the mixture in a high shear mixer. The electrically conductive paste can be applied to a surface of an article to form a coating, or can be molded into an article. The solvent is evaporated, and the electrically conductive paste is cured to provide a graphite-containing resin compound. The graphite-containing resin compound is electrically conductive, and provides low alpha particle emission at a level suitable for a low alpha particle emissivity coating.
