use of titanium dioxide

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 Lithopone B301, Lithopone B311 powder itself may vary in shade over time, ranging from pure white all the way to grey or even black. To suppress this effect, a dopant might be used, like 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.

  • Manufacturers must also consider the particle size distribution of titanium dioxide when formulating their products. Finer particles can lead to improved gloss and smoothness, while coarser particles might be preferred for specific textured effects or to reduce costs without compromising on opacity. The surface treatment of titanium dioxide particles is another aspect that can be tailored to enhance compatibility with different types of binders and additives used in paint formulations.
