Formulations containing an organometallic activator, a filler, a solvent and an aqueous dispersion of a polyure- thane polymer are outstandingly suitable for activation of surfaces of plastics for currentless metallisation thereof. The components of plastic activated in this way are preferably employed, after metallisation has been carried out, for shielding from electromagnetic waves.
