- flexographic printing inks were also produced using conventional polyurethane binders (PUR 7313 (BASF).
- PUR 7313 polyurethane binders
- Test procedure "Tesafestmaschine" serves to determine the adhesion of an ink film on the substrate.
- a tape strip adheresive tape with a width of 19 mm (item BDF 4104), Beiersdorf AG) was stuck onto the ink film, evenly printed and torn off after 10 seconds. This process was carried out four times at the same place on the test specimen, each time with new tape strips. Each tape was stuck on white paper one after the other, on white paper on black paper. The test was carried out immediately after application of the flexographic printing ink.
- Multi-layer materials with various foils were produced with printing inks 1.1 to V5.
- the quality of the composites is determined by determining the bond strength between two foils connected by lamination.
- the lamination film (film 2) is coated with an adhesive-hardener mixture (R&H MOR-FREE A 4123 / hardener C88)) in such a way that a film thickness of approximately 6 ⁇ m resulted.
- Both foils were then pressed in such a way that the printing ink and the adhesive came into contact.
- the composite films obtainable in this way were stored at 60 ° C. for 3 days and the composite value was then determined.
- Table 4 The results of the tests are summarized in Table 4. Test Method:
- Measuring and testing equipment tensile strength tester from Zwick punching tool (width: 15 mm)
- At least 2 strips (width 15 mm) of the composite material to be tested were cut along and across the film web.
- the ends of the punched strips were immersed in a suitable solvent (e.g. 2-butanone) until the materials came apart.
- the pattern was then dried carefully.
- the delaminated ends of the test specimens were clamped in the tensile strength tester. The less stretchable film was placed in the upper clamp.
- the take-off speed was 100 mm / min, the take-off angle of the separated films to the non-separated complex was 90 °.
- the bond value was read off as the mean, given in N / 15 mm.
