The invention relates to a method for producing a bonding of two substrates of which at least one is transparent and of which at least one has a surface having a surface energy (measured according to test method C) of 40 mN/m at maximum, comprising the use off a double-sided adhesive product having a first and a second adhesive surface, wherein the first adhesive surface is covered by a first separating layer and the second adhesive surface is covered by a second separating layer, wherein the pull-off force of the first separating layer from the first adhesive surface, AZK, is less than the pull-off force of the second separating layer from the second adhesive surface, AZK, and wherein the ratio of adhesion force of the fresh bond of the first adhesive surface on a surface having a surface energy (measured according to test method C) of 40 mN/m at maximum (KK, measured according to test method B) to the pull-off force (measured according to test method A) of the second separating layer from the second adhesive surface, KK: AZK, equals at least 13.5, comprising the following step: (a) removing the first separating layer from the first adhesive surface and bringing the first adhesive surface into contact with the surface having a surface energy (measured according to test method C) of 40 mN/m at maximum.
