Zusammenfassung: | Method for the production of gluing of two substrates, from which at least a substrate is transparency and at least a substrate has a surface with a surface energy (measured according to test method C) not more than 40mN/m, included the use of a two-sided adhesive product with a first and a second adhesive surface, wherein the first adhesive surface is covered by a first release layer and the second adhesive surface is covered by a second release layer, wherein the release force of the first release layer from the first adhesive surface, AZK1, is smaller than the second release force from the second adhesive surface, AZK2, and wherein the relation of the adhesive force of the fresh gluing of the first adhesive surface on a surface with a surface energy (measured according to test method C) not more than 40mN/m (KKfrisch, measured according to test method B) to the release force (measured according to test method A) of the second release layer from the second adhesive surface, KKfrisch: AZK2, is at least 13.5, |
