Zinc oxide for phosphating solution is a white powder that is stable at room temperature and has good covering and coloring power. Insoluble in water and alcohol, soluble in acid and alkali ammonium salt solutions, belonging to amphoteric oxides. The absorption of carbon dioxide and water in the air produces zinc carbonate, which appears white, turns yellow when heated, and returns white after cooling.

Molecular formula: ZnO

Molecular weight (%): 99.7%

Density (g/l): 5.606

Content (%): 99.7%

CAS no:1314-13-2

Packaging instructions: 25KG/bag (inner plastic and outer woven)
