Plasmaaktivierung von Polypropylenoberflächen zur Optimierung von Klebverbunden mit Cyanacrylat Klebstoffen im Hinblick auf die mechanischen Eigenschaften - Plasma modification of polypropylene for an optimization of bonds using cyanoacrylate adhesives from a viewpoint of mechanical properties

by Mühlhan, Claus

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.
