In 2019 ELVIAL became the first in Greece and the fifth in the world to introduce vertical electrostatic painting, completely solving the problem of fiber erosion of aluminum. Through the extraordinary process of de-adduction, a healthy 3-8 μm acid layer, obtained under controlled conditions in an aqueous solution of sulfuric acid, is provided. This layer penetrates the aluminum surface and is an ideal substrate for powder adhesion offering maximum anti-corrosion protection without waiting between the two manufacturing stages.
