The invention relates to the field of adhesive tapes, and particularly to adhesive tapes which can be split, for the purpose of the adhesion and the encapsulation of surfaces that are sensitive to permeate. In particular, the invention relates to a method for producing an adhesion using an adhesive tape section that can be split and, in particular, stored, and comprises (iii) at least one adhesive layer that can be split, is provided on at least some sections of the surface, and has a complex viscosity of less than or equal to 105 Pa s measured according to ISO6721-10 at 23deg c and a frequency of 1 rad/s, and that comprises at least one settable liquid adhesive. The aforementioned splittable adhesive tape section, the adhesive tape section that has been split at least once and comprises an adhesive layer split at least once and reduced in layer thickness, and said adhesive layer that has been split at least once, are all provided for the purpose of the multiple adhesion and encapsulation of permeate-sensitive surfaces, preferably, for example, those of optoelectronic arrangements. The invention also relates to a method for producing a barrier layer.
