Metal pigments

Metal pigments play an important role in the coatings industry, particularly in connection with corrosion protection coatings. These pigments consist of fine particles of metallic materials such as aluminum, zinc or special alloys. Their use in anti-corrosion coatings not only helps to create a protective barrier against external influences, but also to improve aesthetic and visual qualities.

The integration of metallic pigments in anti-corrosion coatings offers several advantages. The reflective properties of these pigments not only provide an attractive metallic sheen, but also help to reduce the surface temperature. This cooling effect is particularly important in applications where temperature rises must be avoided to minimize corrosion effects.

Another important aspect is the opacity of the metal pigments, which helps to improve the opacity of the coating. This is particularly relevant in the coatings industry, as high opacity enhances the protective function against UV radiation and other environmental influences. Metal pigments in anti-corrosion coatings also act as active corrosion inhibitors. The layer of metallic particles forms a barrier that slows down the diffusion of hydrogen and oxygen, the main causes of corrosion. This helps to extend the service life of the coated surface.

The development and application of anti-corrosion coatings with metallic pigments require precise coordination of particle size, distribution and concentration in order to achieve the desired mechanical, optical and protective properties. Research in this area contributes to the creation of innovative coating solutions that not only protect against corrosion but are also aesthetically pleasing.
