摘要:
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 10 5 Pa s measured according to ISO6721-10 at 23°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.

The intention was to provide a substantially biodegradable pressure-sensitive adhesive being to a large extent based on materials of biological origin which combines sustainability features with good tack and good adhesion properties on a variety of substrates. This was accomplished by a pressure-sensitive adhesive comprising a polyhydroxyalkanoate, characterized in that the polyhydroxyalkanoate features 1 to 20 weight-% of structural units having a side chain functionalization moiety comprising at least 10 C-atoms.

The present invention relates to the field of adhesive tapes, more particularly to that of cleavable adhesive tapes, for the adhesive bonding and encapsulation of permeate-sensitive surfaces. Specifically the present invention relates to a cleavable adhesive tape which can be kept in storage and which comprises (i) at least one backing layer, (ii) at least one outer layer and (iii) at least one adhesive-bonding layer which is present on at least part of a surface and which has a complex viscosity smaller than or equal to 1000 Pas, measured in accordance with ISO 6721-10 at 23°C and at a frequency of 1 rad/s, comprising at least one hardenable liquid adhesive. The present invention further relates to the provision of the multiply cleavable adhesive tape described, and also of an adhesive tape which has been cleaved at least once, with an adhesive bonding layer that has been cleaved at least once and that has reduced thickness, and also to the, more particularly multiple, use of the adhesive tapes, preferably of the cleavable and/or cleaved adhesive-bonding layers, more particularly for the adhesive bonding and encapsulation of permeate-sensitive surfaces, preferably of optoelectronic arrangements.
