Abstract
A single-sided gasketed panel assembly for use as a flush-mounted panel or window in vehicles, buildings, or other structures, as well as a method and apparatus for making such panel assemblies, wherein the panel assembly comprises a sheet-like panel having; a primer layer and at least one polymeric gasket molded to the panel on the primer layer. The primer applied to the panel has a predetermined transition temperature above which improved adhesion properties are exhibited for polymeric gaskets molded thereon when the primer is at or above such temperature. The method for manufacturing the panel assembly includes applying a primer having a predetermined transition temperature as a coating to a surface of a panel, heating the panel and primer coating to a temperature at least equal to the transition temperature of the primer, and molding a gasket, preferably of a thermoplastic polymeric material, onto the surface of the heated panel and the primer coating while the temperature of the primer coating is at least equal to the primer transition temperature.
