A polymer-based substrate is proposed, which in particular is electrostatically coatable, wherein the substrate has a substrate base body made using a polymeric material and a two- or multi-layer coating applied to a surface region of the substrate base body, wherein a first layer of the coating is configured as a bonding layer and is arranged in contact with the surface region of the substrate base body, wherein a second layer of the coating is configured as a lacquerable cover layer, wherein at least one layer of the coating is produced as a layer with reduced surface resistance using a proportion of an electrically non-insulating material, such that it results in a specific surface resistance of this layer of about 1010 Ohm or less, and wherein at least one layer of the coating is configured as a film.
A polymer-based substrate, comprising a substrate base body made using a polymeric material and a two layer coating applied to a surface region of the substrate base body, the polymeric material comprising reinforcing substances selected from the group consisting of particulate reinforcing substances and fibrous reinforcing substances, wherein a first layer of the two-layer coating is a bonding layer and is arranged in contact with the surface region of the substrate base body, wherein a second layer of the two-layer coating is an electrostatically lacquerable cover layer, wherein the second layer of the two-layer coating is a layer with reduced surface resistance using a proportion of an electrically non-insulating material, such that the electrically non-insulating material results in a specific surface resistance of the second layer of the coating of about 1010 Ohm or less, wherein at least one layer of the two-layer coating is a film, and the polymer-based substrate further comprises a powder lacquer layer applied to the second layer of the two-layer coating wherein the powder lacquer layer is an outermost layer of the polymer-based substrate.
A polymer-based substrate, comprising a substrate base body made using a polymeric material and a multi-layer coating applied to a surface region of the substrate base body, the polymeric material comprising reinforcing substances selected from the group consisting of particulate reinforcing substances and fibrous reinforcing substances, wherein a first layer of the multi-layer coating is a bonding layer and is arranged in contact with the surface region of the substrate base body, wherein a second layer of the multi-layer coating is a layer with reduced surface resistance having a proportion of an electrically non-insulating material, such that the electrically non-insulating material results in a specific surface resistance of about 1010 Ohm or less, wherein a further layer of the multi-layer coating provides a cover layer and is a film, and the polymer-based substrate further comprising a powder lacquer layer applied to the cover layer wherein the powder lacquer layer is an outermost layer of the polymer-based substrate.
