Abstract

What is BS EN 4729 - Chromium-based coatings for aerospace about?

The chemical conversion coating is used in the manufacturing of aerospace products to improve paint adhesion and resistance to corrosion. BS EN 4729 is a part of European metallic material standards that specifies trivalent chromium based chemical conversion coatings for aluminium and aluminium alloys for aerospace applications. BS EN 4729 covers the application by bath but also by touch-up. BS EN 4729 covers coating weight and material specifications, process requirements, pre-treatment methods such as cleaning, pickling, rinsing bath, post-treatment. BS EN 4729
