and Al Surface coatings are mainly used for protection, for decorative or functional purposes. A very thin coating application can improve a substrate's properties or service life without having to change the composition of the entire component material. This makes products more resource-efficient and reduces their environmental impact. Nanoparticles can help further increase resource efficiency and produce functional coatings with new properties. Polymers have many advantages over materials such as metal or glass. They are many times lighter and, in some cases, more stable and corrosion resistant. Wet paints are usually ...
