The Main Factors Affecting the Hiding Power of Titanium Dioxide
Generally, the higher the covering power of titanium dioxide, the higher its achromatic power will be.
1. The refractive index of the pigment crystal itself. The refractive index of titanium dioxide is the highest among white pigments, so theoretically its covering power is also the highest.
2. The shape, size and particle size distribution of titanium dioxide particles. The finer the particle size and the smoother the particle structure, the greater the hiding power in a range greater than the half-wave wavelength of visible light.
3. Good dispersion of titanium dioxide can also improve its covering power.
