    摘要： Die Erfindung betrifft einen Haftklebfolienstreifen aus mindestens zwei, insbesondere drei Schichten, der sich durch dehnendes Verstrecken im Wesentlichen in der Verklebungsebene rückstands- und zerstörungsfrei wieder ablösen lässt, mit einem Träger, auf dem zumindest einseitig eine erste, außenliegende Klebemassenschicht vorhanden ist, wobei
    • die Klebemassenschicht aus einer Klebmasse besteht, die auf Basis von Vinylaromatenblockcopolymeren und Klebharzen aufgebaut ist, wobei zu mindestens 75 % (bezogen auf den Gesamtharzanteil) ein Harz gewählt wird mit einem DACP (diacetone alcohol cloud point) von größer -20 °C, bevorzugt größer 0 °C, und
    • der Träger mindestens eine Schicht aufweist, die aus einem Polyurethan besteht mit einer Reißdehnung von mindestens 100 % und einem Rückstellvermögen von über 50 %.
    Insbesondere dient als Klebrigmacher für die Haftklebemasse(n) ein unpolares Kohlenwasserstoffharz oder ein Polyterpenharz.

    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.

    摘要： The invention relates to an adhesive film strip comprising at least two, particularly three, layers, which adhesive film strip can be detached without residues and nondestructively by expansive stretching substantially in the adhesion plane, with a carrier on which a first external adhesive compound layer is present on at least one side, wherein • the adhesive compound layer consists of adhesive compound formed on the basis of vinyl aromatic block copolymers and adhesive resins, wherein at least 75% of the resin (relative to the overall resin content) is selected with a DACP (diacetone alcohol cloud point) of greater than -20°C, preferably greater than 0°C, and • the carrier has at least one layer made from a polyurethane with an elongation at break of at least 100% and a restoring power of more than 50%. A nonpolar hydrocarbon resin or a polyterpene resin is particularly used as the tackifier for the adhesive compound(s).

    摘要： 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.
