The primers described in this specification, which are lead and hexavalent chromium free, are intended for use on clean, blasted ferrous substrates with the CARC coating system. These coatings use metal particles that make up a part of the pigment content to provide sacrificial cathodic protection to steel substrates. These primers are intended to be applied to blasted steel having a surface profile of 1-2 mils. As a stack up system, which contains a metalrich primer, barrier primer and CARC topcoat will provide enhanced corrosion performance of 80+ cycles on the cyclic corrosion test.
