Abstract

A novel composition (A) comprising a polyamide matrix contains at least 2 (preferably 2-50) wt. % electrically conductive filler (I) and at least 1 (preferably 1-30) wt. % antistatic agent (II). Independent claims are included for the preparation of (A).

Description

technical field [0001] The present invention relates to compositions based on a polyamide matrix comprising conductive fillers and antistatic agents. By shaping such compositions, plastic articles (for example body parts in the automotive sector) can be obtained, wherein the articles have a good ability to be painted by electrostatic deposition painting methods. Background technique [0002] In many industries there is a considerable demand for components made of plastics. This is because parts made of plastic are lighter and easier to design and produce than parts made of steel or aluminum, especially in the automotive industry. [0003] However, problems arise when it is desired to paint plastic parts. [0004] Thus, for example in the automotive field, there are specifically three main methods of painting using electrostatic processes, ie by movement of particles under the influence of an electric current. The first method is called the "inline" method, in which the pl...
