Zinc Oxide (ZnO) has been widely used as a key ingredient in UV-blocking cosmetics and as a protective additive in coating pigments. This material effectively absorbs harmful UV radiation in both the UVA and UVB ranges, and this capability is further enhanced at ultrafine particle sizes. Moreover, its high transparency makes it advantageous for a wide range of applications. SukgyungAT offers high purity, ultrafine zinc oxide particles and supports customers by providing surface modification and customized dispersion services, enabling easier integration into their products.
