  • baffles may be provided to provide seals and sound insulation or structural components may be provided to strengthen and reinforce the structures at particular points.
  • the components frequently comprise carriers coated with heat activatable adhesive and are frequently secured within the structure and the adhesive is formulated so that it develops adhesive properties during the baking step employed in the provision of an anticorrosion coating (sometimes known as e coat) during automobile assembly.
  • the adhesive is also foamable and is formulated to foam at the temperatures at which the adhesive properties are developed this enables the adhesive to be provided on part or all of the surface of the component and the component can be mounted in the cavity in such a way that a gap is provided between the surface of the component and the interior wall of the cavity to allow the interior wall of the cavity to be coated with the anti-corrosion coating.

Abstract

L'invention concerne des systèmes destinés à renforcer des pièces ou à modifier le trajet et à assurer l'étanchéité de celles-ci dans des cavités situées dans des automobiles, notamment pendant la réparation des pièces constituant la cavité après un accident. Les systèmes utilisent un adhésif activé à température ambiante qui est injecté au niveau d'un emplacement situé dans la pièce de renforcement ou de modification de trajet et d'étanchéité. Pour retenir l'adhésif au niveau de l'emplacement, il est nécessaire de former une liaison entre la pièce et la surface interne de la cavité de l'automobile.
