High Grade 99.9%
High Grade 99.9% is a high-purity zinc oxide produced using Special High Grade (SHG) zinc metal via the French process. It offers excellent chemical purity and consistent particle characteristics. Designed for demanding industrial and technical applications requiring reliable performance and controlled impurity levels.
Positioning
High Grade zinc oxide provides elevated chemical purity and consistent quality for demanding applications.
It combines premium purity with cost-efficient positioning and is suitable for a wide range of uses, including industrial formulations as well as selected cosmetic, feed and other applications requiring low impurity levels.
