Abstract
A method for the manufacture of a laminated glass assembly comprising (1) a monolithic or laminated glass and/or plastic support having an glazed edge, and (2) a plastic sheet comprising at least one layer of polyurethane in contact with the surface having the glazed edge is disclosed. In the invention, at least one of the two contact surfaces of the glazed edge with the polyurethane layer is treated, before the assembly of the support with the plastic sheet on an area corresponding essentially to the glazed edge, by the deposit of a primer comprising a reactive mixture having free NCO groups. The free NCO groups are capable of reacting with the glazed support and with the plastic sheet and of forming cross-linking bonds with the other components of the primer at the time of the heat cycle of the subsequent assembly. The plastic sheet is the assembled with the support, and the glass undergoes a heat cycle which enables the reaction of the primer and the definitive peripheral adhesion of the glass.
