One of the main applications of titanium dioxide in paper is in the production of high-quality coated papers. Titanium dioxide is often added to the coating formulations to enhance the whiteness and brightness of the paper surface. This helps to improve the print quality of the paper, as it provides a smooth and even surface for ink to adhere to. The high opacity of titanium dioxide also helps to prevent show-through, making the printed text or images more vibrant and legible.

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.

One of the key advantages of using titanium dioxide in plastics is its ability to improve the mechanical properties of the final product. By adding titanium dioxide to plastic resins, manufacturers can enhance the strength, stiffness, and impact resistance of the plastic, making it suitable for a wide range of applications. Additionally, titanium dioxide helps to reduce the degradation of plastics caused by exposure to UV radiation, thus extending the lifespan of plastic products.
