Zinc oxide used in coating and pigment

1. Characteristics:

1. The particle size of Huiyuan brand zinc oxide used in coating and pigment is small. It has stronger adhesion and hiding power than the one with larger surface area. It greatly improves the effect of coating.

2. The density of this products is small. So it is not easy to form precipitation in using process or the final products.

3. This product still has an effect of shield ultraviolet radiation. So, it plays a role of anti-aging in the coating.

2. Usage:

Huiyuan brand zinc oxide used in coating and pigment can be used in the production of high-grade painting, coating and coating intermediates.

Properties

Zinc oxide is a kind of pure white powder, which is composed of amorphous or needle like small particles. As a basic chemical raw material, it has a wide range of applications, such as rubber electronics, medicine, coatings and other industries. Zinc oxide can be used as white pigment in printing and dyeing, papermaking, match and pharmaceutical industry. In rubber industry, it is used as vulcanizing agent, reinforcing agent and colorant of natural rubber, synthetic rubber and latex. It is also used in the manufacture of pigment zinc chrome yellow, zinc acetate, zinc carbonate, zinc chloride, etc. In addition, it is also used in electron laser materials, phosphors, feed additives, catalysts, etc. In medicine, it is used to make ointment, zinc paste, rubber paste, etc.
