<p>The invention concerns an elastomer system having biocide properties and useful, in particular, for impression, for example, dental impressions. The invention aims at providing an efficient system 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 (silicone fillers, alumina, paraffin, vaseline oil). As for the biocide, it can be provided with an adjuvant using antiseptic quaternary ammonium, even with EDTA-type complexing agents. The invention is useful for impressions in dentistry.</p> |
