Abstract
A composition which provides an elastomeric, electrically conductive product upon removal of the water at ambient conditions is described. The composition comprises an emulsion (A) having a dispersed phase of elastomer and a continuous phase of water containing a material selected from the group comprising colloidal silica, alkali metal silicates, and organosilicates, and (B) electrically conductive, metal coated spheres having a diameter of from 5 to 105 micrometers. Because the dispersed particles of elastomer are crosslinked before the metal coated spheres are added, when the water is removed from the emulsion, the metal coated spheres and the dispersed crosslinked elastomer are found in a continuous polar phase. The cured elastomer, having a surface resistivity of less than 2 ohms per square on at least one surface is particularly useful in producing an efficient shield for electromagnetic radiation in the radio and television frequencies.
