1. CAS No.: 1314-13-2. 2. EC No.: 215-222-5. 3. Zinc oxide is widely used in products such as zinc stearic acid, zinc bromide, zinc borate, phosphorization fluid etc, but also be used for mixing the electroplating solution. The applications of zinc oxide powder are numerous. Most applications exploit the reactivity of the oxide as a precursor to other zinc compounds. For material science applications, zinc oxide has high refractive index, good thermal, binding, antibacterial and UV-protection properties. Consequently, it is added into various materials and products, including plastics, ceramics, glass, cement, rubber, lubricants, paints, ointments, adhesive, sealants, pigments, foods, batteries, ferrites, fire retardants, etc.
