K‐White: Comparative Performance Tests with Zinc Phosphate Available to Purchase

Performance tests were carried out on the anti‐corrosion ability of K‐White, K‐White/zinc phosphate mixtures and modified zinc phosphate on the same cost basis. The results of salt spray tests and humidity tests in a medium oil alkyd primer system have shown that K‐White was much more efficient and cost‐effective even at its lower loading levels, compared with the other pigments.
