The Path to New Zinc-Free Anti-Corrosive Pigments.

The article discusses electrochemical investigation methods that have been used successfully accelerate work on zinc-free anti-corrosive pigments with improved protection. Topics covered include the factors that can be attributed to the mode of action of an anti-corrosive pigment, the requirements of zinc-free pigment technology, and the verification of evidence of the electrochemical investigation methods using traditional corrosion testing.
