Disclosed is a novel method for impregnating bottle corks, wherein the bottle corks are treated with silicon rubber materials, which can be cross-linked to form elastomers, containing organopolysiloxanes comprising (1) radicals with aliphatic carbon-carbon multiple bonds, (2) organopolysiloxanes with Si-bonded hydrogen atoms (3), catalysts promoting the attachment of Si-bonded hydrogen to aliphatic multiple bonds, and optionally (4) agents which delay the attachment of Si-bonded hydrogen to aliphatic multiple bonds, characterized in that the organopolysiloxanes (2) contain 1.02.0 wt. % Si-bonded hydrogen.
