Exploratory Development of Corrosion Inhibiting Primers

While present corrosion inhibiting primers give generally good performance in adhesively bonded structures, they require special handling and application conditions to ensure proper pigment suspension and film thickness and uniformity control. In addition, improvements in primer performance and application economies have become increasingly difficult to obtain with known primer resin formulation technology and available corrosion inhibiting pigments. As a possible solution to some of these problems, major emphasis was placed on development of anti-corrosion materials, which would be soluble, or at least more easily suspendable, then present inorganic chromate pigments.
