Publication number: 20210221104Abstract: Novel multilayer laminates and lamination methods useful for the production of safety glass are disclosed in which an interlayer is provided between substrates and a porous sealant material is provided in a strip around the perimeter of the interlayer and at least partially in-between the substrates adjacent the interlayer. The space between the substrates is evacuated or de-aired through the porous sealant. The porous sealant is then made into a non-porous, continuous perimeter seal by pressing at or near room temperature or at a moderately elevated temperature to remove pores or gaps. The laminate is further processed at higher elevated temperatures either at or near atmospheric pressure or at elevated pressure to increase the bonding between the interlayer and the substrates and to eliminate most or all of the initial texture on the surfaces of the interlayer.Type: ApplicationFiled: April 6, 2021Publication date: July 22, 2021Applicant: Pleotint, L.L.C.Inventors: Michael D.
