Abstract (en)
[origin: WO2022137177A1] The method for producing a plaster comprises the following steps: (1) providing a substrate material; (2) coating an underside of the substrate material with a suitable non-UV-curing acrylate adhesive, which is used here in the form of a solution of a polyacrylate in an organic solvent or solvent mixture, wherein the solvent or solvent mixture is used in an amount of 25 to 70 wt.%; (3) fabricating the plaster; (4) producing a grid structure on the plaster such that this comprises a plurality of crossing strips. According to the invention, the adhesive is applied at a temperature of 90°C to 120°C over a time of 5 s to 60 s, and the plaster is activated, before and/or after the adhesive is applied, by repeated irradiation of the underside using ultraviolet light.
