Emulsion‐based anti‐corrosive primers for metals Available to Purchase

Probably because the atmospheric corrosion of metals is always associated with the presence of water, the idea of using water‐borne coatings to give protection against corrosion has still not achieved general acceptance. Despite the considerable quantities of aqueous solution primers used in car body dip tanks, there remains a fairly deep‐rooted suspicion of aqueous primers. This may be due to the fact that with all other anti‐corrosive coatings the metal surface must be clean and dry, while aqueous systems inevitably wet the surface.
