Zinc flake systems in all industrial sectors

When coating components for various industries, protection of the components against corrosion still takes center stage. A variety of demands and a wide range of articles require high-performance coatings and appropriate application technology in order to be able to handle large volumes reliably. The demands for surface protection are however much more diverse and can include a combination of requirements such as salt spray resistance, resistance to chemical reagents, cyclic loading, UV and temperature resistance and defined coefficients of friction for fasteners. Technical design aspects in terms of color, e.g. black, gloss level and reduction of coating corrosion are added to the list by different OEMs. Zinc flake systems have been established for many years in all industrial sectors. In the automotive industry, zinc flake systems and galvanic zinc-nickel coatings have particularly proven themselves and are by far the leading coating methods used for fasteners. Increasingly, vehicle manufacturers must assure a higher guarantee for functional components of up to 12 years in the field. In other areas, such as chassis components/stamped-bent parts, cathodic dip painting (CDP) is also widely used. However, particularly in exposed installation positions, these systems are coming under increasing pressure, as the price advantage along the value chain is increasingly lost due to the secondary measures required to guarantee the defined service life in the field. Zinc flake systems are continuously gaining market share in terms of service life, application range, application technology and cost-performance ratio.
