    摘要: 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.

    摘要: A non-drip, preferably self-adhesive, silicone elastomer composition crosslinkable by polyaddition, such as those polyorganosilanes (POS) bearing C2═C6≡Si-alkenyl units and ≡Si—H units but excluding fluorinated POS. The composition includes at least a thixotropic additive containing at least a fluorinated resin, preferably based on polyfluoroethylene (PTFE). The composition may be prepared from a Si—Vi polydimethylsiloxane (PDMS) and a Si—H PDMS crosslinked by platinum catalysis. Polytetrafluorethylene, a filler, particularly one containing silicone, optionally a ternary adherence promoter such as vinyltrimethosilane/glycidoxypropyltrimethoxysilane/butyl orthotitanate, and other typical additives may be added to the composition. The composition (not excluding the fluorinated POS as a possible constituent in the composition) may be used to produce joints in situ and/or as an adhesive, particularly in upholstery.

    摘要: The invention concerns a method for preparing a silica suspension in a silicone matrix, said suspension capable of being used for producing organopolysiloxanes crosslinkable by polycondensation. The invention aims at seeking a technical compromise between the rheology of said compositions and the mechanical properties of the resulting crosslinked elastomers. As a solution, the invention discloses a method for preparing a silica suspension treated with organosilazane in a silicone material comprising a linear reactive polyorganosiloxane bearing for example at each chain end a hydroxy group. The invention is characterized in that it consists essentially in introducing the organosilozane in the preparation medium: before and/or substantially simultaneously before bringing together at least part of the silicone material and the particulate filler used, said organosilozane introduction being carried out with a fraction of organosilazane corresponding to a proportion ranging between 8% and 30% by dry weight relatively to the silica filler, and after bringing together the filler and all or part of the silicone material.
