Abstract: A process is disclosed for producing multi-layer laminates of glass and plastic of the type subject to nonsymmetrical thermal shear stress, such as flat or curved glass-plastic laminates or curved glass-plastic-glass sandwiches. Use of difunctional silane-treated glass and an aliphatic polyether polyurethane interlayer allows curing at temperatures low enough to minimize shear stresses which tend to cause delamination or shattering of the thin layer of glass in the finished part. The interlayer of aliphatic polyether polyurethane can be replaced by cured-in-place polyurethane having a polyether backbone, allowing processing at even lower temperatures.

Abstract: A method of handling a glass part to be treated and shaped in a hot liquid bath of a composition having a melting point greater than ambient temperature comprises the steps of: placing at least one glass part on at least one flexible porous member suspended by its edges; immersing the glass part, flexible member and a form in the hot bath; drawing the immersed glass part against the form by pulling the edges of the flexible porous member over the form; removing the form, glass part and flexible member from the bath as a unit, whereupon the glass and a portion of the bath composition hardens, the bath composition clinging to the glass and porous member; removing the form from the glass; and, removing the flexible porous member, and essentially all of the bath composition clinging to the glass. Protection for the glass and further ease of handling are provided where a second flexible porous member is placed between the glass and the form.
