As functional constituents of organic coatings, Pigment Grade Corrosion Inhibitors are intended to operate in atmospheric corrosion conditions.
A brief review of the contemporary chemistry and specific properties of corrosion inhibitor pigments is presented. Concepts relevant to the “inhibitor reservoir” function of pigmented organic coatings are discussed in the context of coatings’ degradation mechanism under atmospheric corrosion conditions.
 Recent progress realized in chromate-free corrosion inhibitor pigment development is discussed.
