Plasmaaktivierung von Polypropylenoberflächen zur Optimierung von Klebverbunden mit Cyanacrylat Klebstoffen im Hinblick auf die mechanischen Eigenschaften
In the present study low pressure plasma pretreatment has been investigated as an alternative to chemical primer pretreatment. The mechanical properties of Polypropylene-Cyanoacrylate bonding which were both, plasma and primer pretreated were compared. From the investigations, where the plasma parameters were systematically varied, it can be concluded that a very short exposure to an oxygen plasma and new curing conditions led to the best results. The shear strength after plasma pretreatment became even higher than after primer pretreatment.
