Title (EN) POLYADDITION-CROSSLINKABLE SILICONE COMPOSITION USEFUL FOR OVERMOLDING PARTS
(FR) COMPOSITION SILICONE RETICULANT PAR POLYADDITION UTILE POUR LE SURMOULAGE DE PIECES
Abstract:
(EN) The field of the invention relates to the use of polyaddition-crosslinkable silicone compositions for the overmoulding of parts, in particular made of thermoplastic resin, by injection-molding processes. Thus, one of the subjects of the invention relates to a process for preparing composite articles composed of a rigid substrate made of glass, metal or thermoplastic resin and of a silicone elastomer with good mechanical properties and a good adhesion between the substrate and the silicone elastomer so that there is a solid connection between the two portions. The composite articles according to invention are used in very diverse fields such as electrical and electronic equipment, motor vehicle and medical equipment and they can be found for example in household appliances, consumer goods, medical equipment and sport and leisure articles.
(FR) Le domaine de l'invention concerne l'utilisation de compositions silicones réticulant par polyaddition pour le surmoulage de pièces, notamment en résine thermoplastique, par des procédés d'injection. Ainsi un des objets de l'invention concerne un procédé de préparation d'articles composites composés d'un substrat rigide en verre, métal ou résine thermoplastique et d'un élastomère silicone avec de bonnes propriétés mécaniques et une bonne adhérence entre le substrat et l'élastomère silicone de telle sorte qu'il existe entre les deux parties une liaison solide. Les articles composites selon l'invention sont utilisés dans des domaines très diverses comme l'équipement électrique et électronique, l'équipement automobile et médical et nous pouvons les trouver par exemple dans les appareils ménagers, les biens de consommation les équipements médicaux et les articles de sports et loisirs.
