ZUR VERKLEBUNG IN EINE RAHMENÖFFNUNG VORGEFERTIGTE FARBZEUGVERGLASUNG UND HERSTELLUNGSVERFAHREN

摘要

Glazing (34) intended to be adhesively bonded in an opening (38), in particular a motor vehicle glazing intended for adhesive bonding in a bodywork opening, is equipped at its periphery with a frame made of elastomer (35) obtained by high-pressure moulding and/or by extrusion. The frame has a U-shaped section whose inner part of the wings (40, 41) is equipped with lengthwise ribs. The adhesive for fitting (42), which is deposited inside the U does not adhere to its surface but, after curing, ensures a purely mechanical bonding. The part of the section comprising the U-shaped section is made of a thermoplastic polyolefin elastomer based on isotactic polypropylene and ethylene-propylene-diene rubber. The adhesive itself is based on one-component polyurethane polymerised by moisture.
