We prepared the paints in accordance with the "HDT experimental formulation" ( Table 2 ). Anticorrosive paints containing 10 % of pigment 2 and 3 proved to be unstable and led to the formation of gritty particles. Despite conducting various trials (changes in amount or type of dispersing agent), we were unable to achieve good paint stability and so did not test these paints. Reasons why the surfactant system of the binder becomes destabilised and why issues arise with paint stability include partial water solubility, oil absorption and the chemical nature of the anticorrosive pigment. As expected, initial ...
