Corrosion inhibited metal pigments

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