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.

Looking ahead, the future of TiO2 industry factories appears poised for further advancement. Emerging trends such as the integration of nanotechnology and the exploration of alternative raw materials promise to revolutionize pigment properties and production processes. Additionally, the ongoing push for circular economy principles will likely result in increased recycling efforts within the industry, reducing reliance on virgin feedstocks and promoting a more sustainable business model.
