CAS NO. : 1314-13-2
EINECS: 215-222-5
Molecular Formula : ZnO
Molecular Weight : 81.38
Properties : White powder,stable under normal temperature, good hiding power and colouring power.Insoluble in water and alcohol ,soluble in acid ,alkali and amkonium solution.
Use: Widely used zinc stearate, zinc bromide, zinc borate, phosphate and other liquid priducts, can also be used to deploy electroplating solution.
Characteristic:
1. Small granule, even granularity, it is possessed of high dispersing ability. The chemical reaction is fast and completely, the reaction speed is identical.
2. The purity is high. As raw material, the product purity is high and stable. There is little impurity, reduce the impact on main products of other resultants.
3. The single granularity density and proportion are small. It is difficult to precipitate in the reaction process.
4. It is pure white color, and has not influenced the result products color after reacting.
