Definitions
- the invention relates to a method for producing at least one-sided Adhesive tapes, wherein between the carrier and adhesive for adhesion promotion Adhesive layers are applied to the carrier.
- primer layers on sheet-like materials for a variety different applications are used.
- Examples are packaging materials, Adhesive tapes or protective films in which adhesion promoter layers in each case are provided in order to achieve sufficient strength of the composite layer.
- Adhesive tapes this is often particularly problematic because generally high Requirements for the adhesion between adhesive and carrier material are made. A detachment of the adhesive from the carrier should neither during the removal of the adhesive tape of the role (before use) still when removing the tape of any Substrate (after use) take place.
- Adhesive layers also called primers can, for example, as a wet chemical coating from solution (Solvent or water) are applied, with subsequent drying and / or networking is necessary.
- Another disadvantage of the flame pretreatment is the high thermal load of the treating materials, so that in particular temperature-sensitive materials can not or only partially be treated.

Examples are the coating of plastic bottles with permeation barrier layers or the scratch-resistant coating of plastic surfaces.
- web-shaped Materials is the use of low pressure plasma polymerization so far in general not useful, since the deposition rates are too low, so that coating time of Minutes or hours. For this is the production of coatings by low-pressure plasma polymerization in sheet-like materials, in particular the production of adhesive layers, uneconomical.
- primers which are applied wet-chemically, usually brings high costs associated with the equipment of the sheet material with a primer a complete additional coating process means. There are also some Primer under environmental and health aspects classified as questionable, in particular because for wet chemical coating of the primer solvents are necessary.
- wet chemical primer is also problematic in rough web-shaped Materials, since it is difficult in these cases, a constant, even Layer thickness to achieve.
- temperature-sensitive materials can only conditionally coated with wet chemical primers, as an economical primer drying when processing web-shaped materials normally drying temperatures of at least 80 ° C is required.

- a carrier or additional gases are preferably non-polymerizable gases such Noble gases, oxygen, hydrogen, nitrogen or compounds respectively Gas mixtures used.
- Additional and carrier gases are used to control the layer deposition and in particular, to increase the uniformity and the stability of the plasma.
- the carriers are preferably Kunststoffoffolien, foam carrier, fabric carrier, non-woven carrier or paper carrier used.

- a rubber adhesive self-polymer of 43% natural rubber, 3% Sillithin Z 86 white, 12% zinc oxide, 21% Escorez® 1202 (exon), 20% Escorez® 365 (exon), 0.4% AS MBI 2 PLV® (Bayer), 0.6% Sontal® (Bayer)
- the adhesion between adhesive and carrier film is checked by an anchoring test.
- adhesive tape with the bonding agent layer according to the invention and a width of 20 mm are glued and rolled on PVC sheets (steel roll, 80 mm diameter, 2 kg weight, is rolled back and forth five times over the adhesive strip at about 10 m / min ).
- PVC sheets steel roll, 80 mm diameter, 2 kg weight, is rolled back and forth five times over the adhesive strip at about 10 m / min ).
- the adhesion between backing film and adhesive is tested after storage by subtracting the test strips at a speed of 2400 mm / min at an angle of 180 ° or 90 °.
- the adhesion between the carrier film and the adhesive is increased substantially and surprisingly strongly and permanently, so that the test strips can be completely removed again.
- the adhesion between adhesive and carrier film is thus significantly better than comparative adhesive films in which instead of the primer layer according to the invention wet-chemical primer or a corona or flame pretreatment were used.
- the comparative adhesive tapes an adhesive failure between the carrier foil and the adhesive was observed in all cases and thus a significantly poorer adhesion between the adhesive and the carrier foil.
