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.
