Because zinc oxide is an amphoteric compound, it can be combined with acidic substances through its alkalinity. In the combination of low acid index, zinc oxide produces zinc soap, which improves the wettability of pigment, makes dispersion easier, and promotes the viscosity of coating to increase slightly and reduces precipitation. In adhesives with high acid index, it will become extremely viscous in containers.

Zinc is a chemical element.

Its chemical symbol is Zn and its atomic number is 30. It is a light gray transition metal.

. Zinc (Zinc) is the fourth most common metal, second only to iron, aluminum and copper, but the most abundant top elements in the earth's crust are oxygen, silicon, aluminum, iron, calcium, sodium, potassium and magnesium. The appearance is silvery white, which plays an indelible role in modern industrial battery manufacturing and is a very important metal.
