Main characteristics of rutile titanium dioxide
Rutile titanium dioxide boasts superior hiding power, generally stronger than that of anatase titanium dioxide. It effectively masks the color and texture of the substrate, resulting in a more uniform coating. Simultaneously, rutile titanium dioxide exhibits higher whiteness and brightness, delivering a brighter, purer white effect and enhancing the aesthetic appeal of the finished product.
