Gold Seal Zinc Oxide

Gold Seal Zinc Oxide is a high-purity (typically 99.7% – 99.9% ZnO), fine white powder manufactured from high-grade zinc using advanced processing methods. It is widely used across industries such as rubber, pharmaceuticals, ceramics, and paints due to its excellent reactivity, UV protection, and antibacterial properties.
