Provided herein are conductive formulations which are useful for applying conductive material to a suitable substrate; the resulting coated articles have improved EMI shielding performance relative to articles coated with prior art formulations employing prior art methods. In accordance with certain aspects of the present invention, there are also provided methods for filling a gap in an electronic package to achieve electromagnetic interference (EMI) shielding thereof, as well as the resulting articles shielded thereby. Specifically, invention methods utilize capillary flow to substantially fill any gaps in the coating on the surface of an electronic package. Effective EMI shielding has been demonstrated with very thin coating thickness.

Rubbery blend containing trans isoprene-butadiene copolymer
