Ergänzungsbeschichtungen

Ergänzungsbeschichtungen, often translated as supplementary or complementary coatings, refer to additional layers applied to a material or surface to enhance its properties or performance beyond that of the primary coating. These layers are not typically the main protective or decorative element but are added to achieve specific functional improvements.

The purpose of an Ergänzungsbeschichtung can be diverse. It might be used to increase scratch resistance, improve adhesion between different coating layers, provide electrical conductivity or insulation, offer enhanced corrosion protection, or act as a barrier against specific chemical agents. In some cases, they can also be employed to modify surface energy, influencing properties like wettability or friction.

The application of Ergänzungsbeschichtungen typically follows a multi-layer coating system approach. The selection of materials and their sequence is crucial and depends heavily on the substrate, the intended application, and the desired final properties. Common application methods include spraying, dipping, or vacuum deposition. The thickness of these supplementary layers is usually minimal, as their primary role is functional rather than providing bulk material properties. Examples can be found in industries ranging from automotive and aerospace to electronics and medical devices, where precise control over surface characteristics is paramount.
