Product Description
Purpose
Chemical grade zinc oxide is widely used in the production of zinc stearate, zinc bromide, zinc borate, phosphating solution and other products, and can also be used to adjust and distribute the plating solution.
Features
1. The particle size is small, the particle size is uniform, the dispersion ability is strong, the chemical reaction speed is fast and thorough, and the reaction speed is consistent.
2. With high purity, the product can be made with high purity and strong stability. Less impurities, greatly reducing the impact of other products on the main product.
3. The density of single particle is small, the specific gravity is small, and it is not easy to precipitate in the reaction process.
4. The color is pure white and has no effect on the color of the product after reaction.
