Corrosion and water diffusion through paint films Available to Purchase

On the basis of earlier studies, an investigation is made into the function of inert and active pigments in anti‐rust paints. Satisfactory explanation of the pigment effect is shown to be impossible without due consideration of the surrounding medium and, if necessary, the substrate. The significance of metal soaps is their increase in the mechanical and chemical resistance of the dried film of binder. This, in turn, results in a reduction of water diffusion through the film in the case of a high PVC and, hence, in an increase in the anti‐corrosive effect.
