Product Usage
Zinc oxide is primarily utilized in the rubber industry as a vulcanization activator and reinforcing agent. In coatings and inks, it serves as a white pigment and corrosion inhibitor. It is also widely used in pharmaceuticals and cosmetics as a raw material for topical formulations and physical sunscreens, as well as in the electronics and photovoltaic sectors for transparent conductive films and buffer layers in solar modules. Additionally, zinc oxide can function as a food or feed additive for zinc supplementation, a ceramic flux, and an adsorbent or photocatalyst in environmental applications.
