Abstract: A method (10) for coating a substrate including at least an elastomer substrate portion with a conductive coating is described. The method includes steps of (i) providing a substrate comprising elastomer material and (ii) coating (13) the substrate with an adhesion promoting layer. The layer comprises a thin layer of B stage heat curable epoxy. The method also includes steps of (iii) pre-curing (15) the adhesion-promoting layer, (iv) disposing (17) a conductive coating atop the layer and (v) post-curing (19) the adhesion-promoting layer.
