The opening force of a laminate or adhesive tape should remain constant for a very long period of time. In laboratory testing, the aging can be accelerated by increasing temperature and pressure. Nevertheless, such an accelerated aging test may take 6 months time, or even longer. Due to the long duration of such a test a systematic study is much more preferable compared to individual measurements.
In a systematic evaluation we tested the long time aging performance of nine different HotMelt adhesives. The results can contribute important information to the development of laminates and adhesive tapes when it comes to UV Silicones.
