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.
