The hardness of white corundum coating mainly comes from the high hardness of white corundum itself. The following is specific information about the hardness of white corundum coating:

I. Hardness of white corundum

The Mohs hardness of white corundum is 9.0, Vickers hardness is 2000-2200 kg/cm, and Rockwell hardness is 75-76HRC. This high hardness makes it possible to significantly improve the wear resistance and scratch resistance of coatings.

II. Hardness performance of white corundum coating

Significantly improve the hardness of the coating: the high hardness of white corundum can significantly improve the hardness and wear resistance of the coating, making it resistant to scratching and mechanical wear. For example, after adding white corundum to the floor coating, the hardness and wear resistance of the coating are significantly improved, and it can withstand frequent friction such as people and traffic.

Enhance the durability of the coating: the fine size and high uniformity of white corundum particles enable it to fill the tiny pits in the coating and further polish the coating surface to make it smoother and more delicate. This characteristic not only improves the hardness of the coating, but also enhances the durability of the coating.

Suitable for a variety of scenes: the high hardness of white corundum coating makes it suitable for a variety of high-friction scenes, such as industrial floors, automobile coatings and so on. In these scenes, white corundum coating can effectively resist the friction and wear of external objects and prolong the service life of the coating.

III. Application of white corundum coating

White corundum coating is widely used in the following fields because of its high hardness and wear resistance:

Floor coating: used in industrial workshops, parking lots and other places to improve the wear resistance, skid resistance and chemical corrosion resistance of the floor.

Automotive coatings: Improve the wear resistance and weather resistance of body coatings, and reduce surface damage caused by friction or environmental erosion.

Industrial protective coating: Among the anticorrosive coatings, white corundum can enhance the wear resistance and high temperature resistance of the coating, which is suitable for metallurgical and mining equipment protection.

To sum up, the hardness of white corundum coatings mainly comes from the high hardness characteristics of white corundum itself, which can significantly improve the wear resistance, scratch resistance and durability of coatings, and is widely used in various high-friction scenes.
