Zusammenfassung: | Use of the adhesive mass K for bonding on surfaces with high polarity, wherein the adhesive mass K is the cross-linking product of a polymer mass comprising at least the following components (A) of at least one polymer component A comprising: (i) greater than or equal to 60 wt% to less than or equal to 80 wt%, relative to the amount of the polymer component A, of at least one component A1, wherein the component A1 comprises: (i-a) greater than or equal to 1 wt% to less than or equal to 15 wt%, relative to the total amount of component A1, of compounds comprising at least one monomer a, having at least one ethyenically unsaturated bond, which is respectively selected such that the glass transition temperature TG of the corresponding homopolymer of the respective monomer a is at least 0 °C, wherein at least a part of the total amount of monomer a is present as compounds comprising at least one monomer a1, having at least one ethylenically unsaturated bond and at least one carboxylic acid group, and (i-b) is greater than or equal to 85 wt% and less than or equal to 99 wt%, relative to the total amount of component A1, at least one monomer b selected from the group of acrylic acid ester and/or methacrylic acid ester, respectively selected such that the glass transition temperature TG of the corresponding homopolymer of the respective monomer b is less than or equal to -30 °C, wherein the (i-a) at least one monomer a and the (i-b) at least one monomer b are present in a total amount of 100 wt% in the component A1, (ii) is greater than or equal to 20 wt% and less than or equal to 40 wt%, relative to the amount of polymer component A, at least one resin component A2, wherein the (i) at least one component A1 and the (ii) at least one resin component A2 are present in a total amount of 100 wt% in the polymer component A, and (B) at least one cross-linking component B comprising covalently cross-linked bi- or polyfunctional compounds, wherein the (A) at least one polymer component A and the (B) at least one cross-linking component B are present in a total amount of greater than or equal to 95 wt% of the total composition of the polymer mass, and wherein the surfaces of high polarity comprise (I) at least one hydroxy-, carbonyl-, carboxy-, SH-, NH- group and/or at least one ionic group and/or (II) at least one adsorbed compound capable of migration containing at least one hydroxy group. |
