Abstract
An elastomer system having biocide properties is described, useful, in particular, for dental impressions. An efficient system is provided for destroying microbes, without adversely affecting the crosslinking properties and the mechanical qualities of RTV 2 elastomers. Said system comprises an RTV 2 silicone, preferably SiH/SiVi polyaddition product and a biocide selected among active chlorine precursors, preferably among N-chloramines. The system may include functional additives (silicon fillers, alumina, paraffin, vaseline oil). As for the biocide, it can be provided with an antiseptic auxiliary adjuvant along with EDTA-type sequestering agents.
