A process is for manufacturing a complex motor vehicle glazing including a glass pane, an elastomer seal and a metal insert overmolded by the elastomer seal. The process includes inserting an edge of a glass pane and a metal insert into an encapsulation mold forming a leaktight cavity around the edge of the glass pane, filling the leaktight cavity containing the edge of the glass pane and the metal insert, by injecting an encapsulation composition including a polypropylene (PP)/thermoplastic elastomer (TPE) compound in the molten state, cooling the encapsulation composition to form an elastomer seal in which the metal insert is integrated, and releasing the elastomer seal from the mold. The PP/TPE compound includes from 30% to 80% by weight of polypropylene (PP) and the metal insert is covered over its entire surface liable to come into contact with the encapsulation composition, with a polypropylene coating.

Encapsulation method

A vehicle luminous signaling glazing forming, for example, a laminated vehicle windshield includes a first exterior glazing, with first main face and second main face, a lamination interlayer made of polymeric material with an other edge face, a second interior glazing, with third main face and fourth main face, the second main face and the third main face being the internal faces of the laminated glazing. The glazing also includes a flexible carrier for the diodes including a diode zone, an emerging electrical supply zone emerging from the other edge face, divided into a plurality of track strips, carrying electrical tracks, with an individual width Wi of less than 5 cm.
