Why Zinc Metal Pigment should not need to be classified as dangerous good ?
Since, – our products, as a result of the design of the production process*, intentionally contain 2 different substances, Zinc and Zinc oxide, next to a free flowing agent – the Zinc powders and Zinc dusts produced by UMICORE Zinc Chemicals have been duly tested and verified to be of the non-flammable type**. * From Zinc powder/dust to Zinc Metal Pigment Zinc powder is manufactured by air, water or centrifugal atomisation, or by a combination of these processes, of a stream of molten zinc metal. Subsequent operations are screening and packing. The very fine zinc powder (also called zinc dust) is normally produced by condensation of zinc vapour in an inert atmosphere. If produced under these conditions, zinc powders would be pyrophoric and would have very bad flowing behaviour due to electrostatic loading of the particles. UMICORE produces fine zinc powders by condensation as well as by atomisation processes during which a controlled oxidation of the powder is induced to ensure that it
