Anticorrosive pigments, role

For corrosion-protective purposes, the most important components of a coating are the binder and the anticorrosion pigment. Additives are necessary for the manufacture, application, and cure of a coating however, with the exception of corrosion inhibitors, they play a relatively minor role in corrosion protection. 

Apart from optical properties such as color and hiding, certain pigments are used in protective coatings to increase their corrosion resistance properties. The anticorrosive pigments used in conjunction with suitable binder in protective coatings systems play a major role in protection of metals from corrosion.
