Abstract

L'invention concerne un procédé de fabrication de vitrages automobiles, comprenant a) la mise à disposition d'une vitre avec deux faces principales et une tranche, ayant une forme permettant, sans déformation additionnelle, de l'incorporer en tant que vitrage dans la carrosserie d'un véhicule, b) l'application, sur moins une face principale de la vitre le long du bord de celle-ci, d'une composition de primaire de manière à former, après séchage, une couche de primaire, c) chauffage de la vitre et de la couche de primaire jusqu'à une température comprise entre 60 et 130 °C de manière à activer la couche de primaire, d) insertion de la vitre dans un moule d'encapsulation de manière à ce que la cavité du moule forme un cadre étanche autour du bord de la vitre portant la couche de primaire activée, e) injection d'une composition d'encapsulation fluide dans la cavité du moule, f) durcissement de la composition d'encapsulation, et g) démoulage du vitrage, caractérisé par le fait que l'étape (c) de chauffage de la vitre comprend le chauffage sélectif de la zone périphérique de la vitre couverte par la couche de primaire à une température comprise entre 60 et 130 °C, tandis que la majeure partie de la partie centrale de la vitre, non couverte par la couche de primaire, reste à une température inférieure à 40 °C.The invention relates to a method for manufacturing automobile glazing, comprising a) the provision of a glazing with two main faces and a wafer, having a shape allowing it, without additional deformation, to be incorporated as glazing in the vehicle body, b) applying, on at least one main face of the window pane along the edge thereof, a primer composition so as to form, after drying, a primer layer, c) heating the glass and the primer layer to a temperature between 60 and 130 ° C so as to activate the primer layer, d) inserting the glass in an encapsulation mold so that the cavity of the mold forms a sealed frame around the edge of the glass carrying the activated primer layer, e) injection of a fluid encapsulation composition into the mold cavity, f) hardening of the encapsulation composition, and g) demolding glazing, characterized p ar the fact that the step (c) of heating the glass comprises the selective heating of the peripheral zone of the glass covered by the primer layer at a temperature between 60 and 130 ° C., while most of the central part of the glass, not covered by the primer layer, remains at a temperature below 40 ° C.
