ABSTRACT:
Compositions containing at least one liquid polydiorganosiloxane having an average of two ethylenically unsaturated hydrocarbon radicals per molecule, an organohydrogensiloxane curing agent, a platinum catalyst and a thermally conductive filler consisting, at least in part, of zinc and magnesium oxides are curable to yield elastomers. The high abrasion resistance, low durometer hardness and high heat conductivity of the elastomers make them particularly useful as coatings for the fuser rolls of electrostatic copiers.
