Produce black oxide coatings on iron and steel surfaces


UltraBlack Blacking Salts are designed to produce black oxide coatings on iron and steel surfaces which, when impregnated with an oil, produces a uniform black finish. The depth of colour is dependent upon the substrate and tank process sequence. The corrosion resistance is dependent on the type of oil finish used.
