The North American region suffered from the excess influx of material in the market, especially from the Asian countries, in the first half of the third quarter. The quarter, however, showed signs of significant improvement with a rise in the number of offtakes. Further, the lack of labor in the US challenged the rates of production of titanium dioxide and resulted in the depletion in the level of existing inventories, pushing the titanium dioxide price graph in an upward direction.

In the manufacturing industry, sometimes many products require coloring, and the ideal coloring material is lithopone. This is a product manufactured through chemical methods. It is a mixture of barium sulfate and zinc sulfide. When the product contains more zinc sulfide, its effect will be better, that is, the coloring ability will be more stable. If you want to buy high-quality lithopone, you have to understand its properties and characteristics. Today’s article will give you a detailed understanding of lithopone.

Although barium sulfate is almost completely inert, zinc sulfide degrades upon exposure to UV light, leading to darkening of the pigment. The severity of this UV reaction is dependent on a combination of two factors; how much zinc sulfide makes up the pigments formulation, and its total accumulated UV exposure. Depending on these factors the pigment itself can vary in shade over time, ranging from pure white all the way to grey or even black. To suppress this effect, a dopant may be used, such as a small amount of cobalt salts, which would be added to the formulation. This process creates cobalt-doped zinc sulfide. The cobalt salts help to stabilize zinc sulfide so it will not have as severe a reaction to UV exposure.
