Abstract
Description
technical field
[0001] The present invention relates to dielectric coatings and articles having a high but well-defined surface resistivity. Background technique
[0002] In many applications with dielectric coatings or with articles consisting primarily of dielectric materials, such as plastic parts, films or tapes, it is necessary to specifically modify the electrical properties of the material. This is usually done by using suitable additives with corresponding properties, such as fillers or pigments.
[0003] It is therefore known to significantly increase the conductivity of layers of dielectric binders, for example by adding conductive pigments.
[0004] Conductive pigments are currently used in various fields of application, for example for antistatic coatings, antistatic floor coverings, antistatic treatment of explosion-proof rooms or as conductive primers for painting plastics.
[0005] In these applications, low surface resistance and volume resistance are neces...
