Abstract

Preparations for the sealing of tires with punctures are proposed, which contain the latex of synthetic isoprene rubbers or the latex of natural rubber together with latexes of synthetic isoprene rubbers, acrylate rubbers and/or methacrylate rubbers. The sealing preparations can contain an adhesive resin compatible with the latexes from the group comprising polyvinyl esters, polyvinyl alcohol and/or polyvinyl pyrrolidone, and also a pigment, with natural rubber latex, synthetic rubber latexes or their mixtures being used as rubber latex. Furthermore, an apparatus is described for the sealing and pumping up of the tire using an airbag inflation charge and also tires with an integrated sealing preparation.
