Abstract: A process is provided for preparing composite articles composed of a rigid glass, metal or thermoplastic resin substrate and of a silicone elastomer with good mechanical properties and good adhesion between the substrate and the silicone elastomer E such that there is a solid bond between the two parts. The composite articles are used in very diverse fields such as electrical and electronic equipment, motor vehicle and medical equipment, and they may be found, for example, in household appliances, consumer goods, medical equipment and sports and leisure articles.

Abstract: The field of the invention relates to the use of polyaddition-crosslinking silicone compositions for the overmoulding of parts, notably made of thermoplastic resin, via injection processes. Thus, one of the subjects of the invention relates to a process for preparing composite articles composed of a rigid glass, metal or thermoplastic resin substrate and of a silicone elastomer with good mechanical properties and good adhesion between the substrate and the silicone elastomer E such that there is a solid bond between the two parts. The composite articles according to the invention are used in very diverse fields such as electrical and electronic equipment, motor vehicle and medical equipment, and they may be found, for example, in household appliances, consumer goods, medical equipment and sports and leisure articles.
