Chromium VI-free coating - nanopassivation A3K in accordance with ISO 4042
Background
Legal requirements such as the "EU End-of-Life Vehicles Directive" 2000/53/EC, the WEEE 2002/96/EC, and the ROHS 2002/95/EC on the prohibition of Cr-6 in coatings require compliance with certain limits for components used in electronics, electrical equipment, and the automotive industry, among others.
Solution
When considering offering our stock with Cr-6-free coating, quality, price, and availability were the decision criteria. Nanopassivation overall convinced us the most: This is a further development of the proven Cr-6-free blue and thick-film passivation, which provides a stable process.
