The content of titanium dioxide in the color masterbatch is the same, but the hiding power of the product produced by adding two color masterbatches in the production is as much as twice as that of the product. I encountered this situation twice, both in the production of sheet manufacturers, one is PS , One is PET, is there any secret recipe to increase the hiding power of titanium dioxide by 100%?

No best answer

Titanium dioxide must reach 100% coverage, which is closely related to the hue, particle size distribution, titanium dioxide, and titanium dioxide dispersion. The particle size distribution and dispersibility of titanium dioxide are particularly important. In order to make the particle size distribution and dispersibility of titanium dioxide good, the surface of titanium dioxide must be modified by powder surface modifiers to eliminate the ultrafine particles of titanium dioxide. To achieve the effect of uniform dispersion, this is the prerequisite for the hiding power of titanium dioxide to reach 100%.
