Why add white corundum powder when producing coatings?
The main reasons for adding white corundum micropowder to coatings include the following aspects:
Improve wear resistance and extend service life: White corundum has high hardness and wear resistance. Adding it as a filler to the coating can significantly improve the wear resistance of the coating and extend the service life of the coating. For example, adding white corundum micropowder to anti-skid coatings can significantly improve the wear resistance of the coating, making it better resistant to external friction and wear, thereby maintaining the integrity and anti-skid effect of the coating.
Enhanced adhesion: The addition of white corundum micropowder helps improve the adhesion between the coating and the substrate, making the coating stronger. This helps reduce coating peeling and aging, ensuring the coating remains stable over long periods of use.
Improve hardness: The hardness of white corundum micron powder can significantly increase the hardness of the coating, making it more scratch-resistant. This is particularly important where high hardness coatings are required.
Improve gloss and texture: White corundum micro-powder is as fine as flour, which can improve the gloss and texture of the coating, making the coating more beautiful. By adjusting the particle size of white corundum powder, the surface roughness of the coating can be controlled to meet the needs of different customers.
Enhanced anti-slip effect: The uniform distribution of white corundum micropowder in the coating can form tiny protrusions and depressions, increasing the roughness of the coating surface, thereby increasing the friction between the coating and the sole or other contact surfaces, thereby enhancing anti-slip Effect.
Improve corrosion resistance and chemical stability: White corundum powder has stable chemical properties and can resist erosion by chemicals such as acids and alkalis, so it can improve the corrosion resistance and chemical stability of coatings. This is especially important for coatings used in harsh environments.
Enhance crack resistance and weather resistance: White corundum powder can enhance the crack resistance and weather resistance of coatings and reduce aging and shedding of coatings. These characteristics are particularly important in coatings used outdoors or in harsh environments.
Environmental performance: White corundum powder is non-toxic, odorless, and pollution-free, meeting environmental protection requirements. No harmful substances are produced during production and use, which is environmentally friendly.
In summary, the application of white corundum micropowder in coatings not only improves the physical properties and chemical stability of the coating, but also improves the aesthetics and environmental performance of the coating, making it widely used in many fields.
