Abstract
A polymer-based substrate is proposed, which in particular is electrostatically coatable, wherein the substrate comprises a substrate base body made using a polymeric material and a coating applied to a surface region of the substrate base body, wherein the polymeric material comprises a first polymer, wherein the coating comprises a matrix polymer and an additive which is dispersed in the matrix polymer and reduces the surface resistance of the coating, said additive having a proportion that is selected such that the specific surface resistance of the coating is about 1010 Ohm or less, and wherein the matrix polymer is selected such that it is compatible with the first polymer.

A polymer-based substrate, comprising
- a substrate base body made using a polymeric material and a coating applied as a layer to a surface region of the substrate base body, wherein the polymeric material comprises a first polymer,
- wherein the coating comprises a matrix polymer and an additive which is dispersed in the matrix polymer and reduces the surface resistance of the coating, said additive providing a specific surface resistance of the coating of 1010 Ohm or less,
- wherein said coating has a thickness in the range of 0.1 μm to 25 μm,
- said first polymer and said matrix polymer being selected from the polymer groups polyamide, polyester, polyether, polyketone, polyvinyl, polyolefin and copolymers thereof;
- and wherein the matrix polymer is selected such that it is compatible with the first polymer, said polymer-based substrate further comprising a powder lacquer layer having a layer thickness in the range of 10 μm to 300 μm.
