Two sets of experimental primer paints, incorporating active pigments not commonly used in primers for steel, have been exposed in Durban for about two years, and have also been exposed to salt-spray testing. Commercial primer paints were also exposed under similar conditions to act as controls. Some of the experimental paints have performed very well, frequently surpassing zinc chromate or red lead primers, although the zinc-rich primers were superior. The results have shown that the incorporation of iron oxide with the active pigments in the experimental paints has greatly improved their performance on exterior exposure in Durban. A further notable observation is the lack of correlation between salt-spray testing and exterior exposure for predicting primer performance. Order from BSRA as No. 47,003.
