Abstract

The present invention relates to the use of paraffin waxes or microwaxes in silicone pastes, in particular in kneadable compositions for the production of accurate impressions of teeth. The silicone pastes are preferably cold-vulcanizing two-component silicone rubber systems which are known per se and in which two pastes are mixed and then crosslink after about 2-5 minutes at room temperature.
