Abstract
A thermoplastic polyamide molding composition having improved impact strength is disclosed. The composition contains polyamide, an electrically conductive carbon in particulate form and a graft polymer. In one preferred embodiment the composition further contains mineral particles. The composition is especially suitable for direct online lacquering without the necessity for pre-treatment of the molding with an electrically conductive primer system.
Claims16
