ELIMINATING ADHESION DIFFERENCE DUE TO GLASS ORIENTATION IN LAMINATED SAFETY GLASS

摘要

A laminar structure comprised of at least two layers (16, 20) of glass and a sheet (18) of plasticized PVB containing an adhesion control additive is provided wherein the difference in adhesion between the PVB interlayer and the glass due to glass orientation is minimized by including a leveling agent in the bulk or on the surface of the sheet of plasticized PVB or by coating the leveling agent onto the glass prior to laminating.
