Abstract: The invention relates to a method for the additive manufacturing of a silicone elastomer article using a 3D printer. The invention also relates to a crosslinkable silicone composition for the additive manufacturing of a silicone elastomer article.

Abstract: Described are organopolysiloxane compositions that are capable of cross-linking and/or of hardening by polyaddition reactions so as to produce elastomers or materials made of silicone. Further described, is how the composition is useful for making a dental impression in the context of preparing prostheses.

Abstract: A crosslinkable silicone material made of a silicone elastomer by polyaddition reaction is provided. The crosslinkable silicone material is especially useful for taking impressions such as, for example, dental impressions.

Abstract: The invention relates to a setting silicone material to give a silicone elastomer by polyaddition reactions, particularly useful for taking imprints, for example dental imprints. The aim of the invention is a material which has a level of hydrophilicity characterised by achieving contact angles &thgr; (cf. FIG. 1 where (1) represents the surface of a film of set silicone material and (2) represents the drop of water deposited on said surface) which can be as low as those from 25 to 27°. The invention is based upon the introduction into the setting silicone material of particularly: (a) at least one non-ionic surfactant comprising an ester obtained by esterification of a C10-C14 fatty acid with a poly(oxyalkylene) glycol of low molecular weight; or a synergistic mixture of (a)+(b) where (b) is at least one non-ionic surfactant comprising a polyalkoxylated C5-C16 fatty alcohol of low molecular weight.

Abstract: Silicone material crosslinkable into silicone elastomer by polyaddition reactions is described. A material is provided offering a compromise between the following characteristics: fluidity (in non-crosslinked state), hydrophilicity (in non-crosslinked or crossliked state) and high mechanical properties (in crosslinked state). The following materials are added to crosslinkable silicone material: (i) a reinforcing siliceous filler in the form of a suspension obtained by subjecting the filler to a treatment in two stages by an agent providing compatibility and by operating in the presence of a polyorganosiloxane with Si-alkenyl functions; and (ii) one or more non-ionic, ionic or amphoteric surfactants. Said silicone material is particularly useful for impressions, for example dental impressions and for making pads used in pad printing techniques.

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.
