IMPROVED MULTIPLE LAYER PANELS HAVING REDUCED LEVELS OF EDGE DEFECTS

摘要

A process for producing a multilayer glass laminate panel having two glass sheets with a polyvinyl butyral) interlayer sandwiched therebetween, the process comprising the steps of: providing two glass sheets; providing a polyvinyl butyral) interlayer, and inserting the interlayer between the two glass sheets to produce a laminate; removing air from the produced laminate; applying heat and pressure to the laminate for a hold time, wherein the laminate is free of bubbles at the edges of the laminate. The multilayer glass laminate panel has improved optical properties, and specifically reduced levels of edge defects, such as edge bubbles in the laminate.
