Abstract (en)
[origin: EP3144414A1] The present invention provides a process for pretreating a polyamide surface in preparation of metallization, the process comprising the steps: (a) providing an object having a polyamide surface; (b) treating the polyamide surface with a protease; and (c) removing the protease from the treated polyamide surface, thus providing an object having a protease treated polyamide surface. The subsequent metallization is preferably a copper metallization using a palladium catalyst (in particular a Pd/Sn activator).
