Abstract
The present invention provides an electrically conductive sheet molding compound composition adapted for electrostatic painting comprising a resin mixture including about 20 to about 60% by weight of thermoplastic resin based on the total weight of said resin mixture, the thermoplastic resin being selected from the group consisting of styrene-butadiene rubber, polystyrene, saturated polyester resin, and mixtures thereof; fibrous reinforcing material; and conductive material. The conductive material is added to the sheet molding compound composition in a sufficient quantity to render an article molded with said composition with structural integrity and electrically conductive enough to be electrostatically painted.
