Titanium dioxide (TiO2) is the most suited white pigment, to give a coating - whiteness and hiding power. This is because, it does not absorb visible light and it has a high refractive index.
However, the pigment is expensive, especially when volume prices of systems are used. But, practice shows that the best cost / performance ratio can be obtained, if the system is studied well and checked whether, TiO2 particles in your system are:
» Separated from each other
» Stabilized sufficiently against flocculation
» Distributed well
» And more…
