Abstract
The present invention relates more specifically to silicone compositions which can be crosslinked into an adhesive gel by hydrosilylation at room temperature, as well as to the gels thus obtained. One of the objects of the invention is to produce, easily and rapidly, gels having viscoelastic qualities, low-temperature physical stability and adhesion properties. This objective is achieved by virtue of the compositions comprising: PA1 a polyorganosiloxane POS (I) of the SiVi type (Vi=vinyl); PA1 a POS (II) of the SiH type; PA1 an extender POS (III) of the .alpha.,.omega.-hydrogen, SiH type; and, optionally, a diluent POS (IV) of the polydimethylsiloxane type; where ##EQU1## Application: protection of electronic equipment (potting), adhesives, prostheses.
