Product use:

Coating zinc oxide is mainly used in high-grade paint, coating and other products and the production of coating intermediates.

Features and functions:

1. Coating zinc oxide particle size is small, specific surface area is large, has strong adhesion and hiding power, greatly improve the efficacy of coating.

2. The proportion of zinc oxide coating is small, and it is not easy to form precipitation in the use or final product.

3 coating zinc oxide also has a certain uv shielding effect, can play an anti-aging role in the coating.It is also a traditional metal preservative.

Packing and transportation:

1, plastic inside and outer double layer packaging

2, standard package weight: 25kg

3, can also be packed according to user needs

4, pay attention to moisture-proof during transportation and storage
