A new pigment to be used in combination with zinc dust in zinc‐rich anti‐corrosive paints Available to Purchase

Zinc‐rich paints (ZRP) are considered to be an important technological development for corrosion protection. The percentage of zinc corroded during the cathodic protection stage of zinc‐rich coatings is relatively small in comparison with the initial total zinc content. This fact, together with the relatively high cost of zinc, the desire to avoid some interferences with the welding process, and the sedimentation of the zinc dust in cans, are some of the reasons to search for co‐pigments (extenders) in ZRP formulas. In the paper the anti‐corrosive performance of ZRP formulas including a new conductive inorganic co‐pigment of low specific density (SVUOM) are shown.
