Molecular formula: ZnSBaSo4 Nature: Also known as Zinc barium white, non-toxic white power, do not dissolve in water, and acid decomposition Produce hydrogen sulfide. And hydrogen sulfide and al kali not work. Heat-resistant and can be improve weather Ability, anti-algae, had excellent cover of the white.

Properties: White powder O Uses: Lithopone is a white pigment composed of a mixture of barium sulfate (28 -30%) and zinc sulfide (68 - 70%) With trace amounts of zinc oxide. It is produced by precipitation through filtering, heating and quenching works. Lithopone has mostly been replaced by titanium dioxide which is more durable, but it is much cheaper. It is used as a Base for lake pigment and used as a inert pigment for paint, ink and cosmetics as well as in a large range of Applications in plastic industry. It is used as a filler in paper, leather, and linoleum.
O Storage: To avoid ultraviolet radiation O Packing: 25kg or 50kg p. P. Bag
