ABSTRACT:
The preformed assembly of a transparent sheet material and a gasket adhered to the periphery thereof, and the method for producing the assembly. Preferably, the sheet material is glass and the gasket is formed of a thermosetting polyurethane material. The material, curable to produce the gasket, is injected into a mold cavity and thence by controlling the attendant parameters, the autogeneous pressure incident to polymerization causes the material to be urged into intimate contact with mold cavity and the sheet material. After the material has been cured sufficiently, the resultant assembly is removed from the mold cavity.
