Flake‐shaped particles of aluminium are well known in the coatings and printing ink industry as “silver bronze pigments”. For their use in waterborne coatings or outdoor applications, an effective corrosion protection of the highly reactive aluminium surfaces is required. The traditional stabilization techniques for aluminium pigments are based on the addition of corrosion inhibitors or on chromate passivation. This publication presents new developments in the encapsulation of metallic pigments that are based on modern sol‐gel techniques. All products are heavy metal‐free and provide excellent applicational properties.
