The role of white corundum in coatings

The role of white corundum in coatings
White corundum has the characteristics of high hardness and high wear resistance. Adding white corundum to the side wall of the coating can play the following roles:
1. Improve the hardness and wear resistance of the coating
Adding white corundum to the coating can increase the hardness and wear resistance of the coating, thereby reducing the wear and aging of the coating film and making it more durable.
2. Improve the spray power of the coating film
Due to the uniform fine size and height of the white corundum particles, it can fill the tiny pits in the coating film, improve the surface pitiness of the coating film, and improve the coating force and pattern of the coating film.
3. Improve the glassiness of the coating film
Due to the high structure and smoothness of white corundum particles, it can act as an abrasive in coatings, making the coating surface smoother and improving the glassiness and visual effects of the coating film.
