How does white corundum powder improve the performance of coatings?
Improve wear resistance and extend service life: White corundum has high hardness and wear resistance. improving the wear resistance of the coating and extend the service life of the coating.
Enhance adhesion: The addition of white corundum helps to improve the adhesion between the coating and the substrate, making the coating more solid. This improvement in adhesion helps to reduce the phenomenon of coating shedding and aging, ensuring that the coating remains stable during long-term use
Improve hardness: White corundum has a high hardness and can significantly improve the hardness of the coating, making it more scratch-resistant. This is especially important for occasions that require high-hardness coatings, such as coatings for mechanical equipment and industrial equipment.
Improve gloss and texture: White corundum powder is as fine as flour, which can improve the gloss and texture of the coating and make 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 for the surface roughness of the coating, such as anti-slip coatings, decorative coatings, etc.
Enhance the anti-slip effect: The uniform distribution of white corundum in the coating can form tiny bumps and depressions, increase the roughness of the coating surface, thereby increasing the friction between the coating and the sole or other contact surface, and thus enhancing the anti-slip effect. This is especially important for coatings that require anti-slip functions, such as stair coatings, bathroom coatings, etc.
Improve corrosion resistance and chemical stability: White corundum has stable chemical properties and can resist the erosion of chemicals such as acids and alkalis. Therefore, adding it to the coating can significantly improve the corrosion resistance of the coating and protect the substrate from the erosion of chemicals. This is of great significance for coatings that need to be used in corrosive environments, such as ship coatings, chemical equipment coatings, etc.
Enhance crack resistance and weather resistance: White corundum powder can enhance the crack resistance and weather resistance of the coating and reduce the aging and shedding of the coating. These characteristics are particularly important in coatings used outdoors or in harsh environments.
In summary, the application of white corundum powder in coatings can significantly improve the various properties of coatings, including wear resistance, adhesion, hardness, gloss, anti-slip effect, corrosion resistance, crack resistance and weather resistance. These performance improvements can not only extend the service life of the coating, but also improve the safety and reliability of the coating, meeting the needs of different fields for high-performance coatings.
