TiO2 is among the costliest ingredients in many paints and as such its efficient use is critical for the commercial success of a given formulation. Many formulators are unsure of the optimal level of TiO2 in a paint from a cost standpoint. Determining this optimal pigment volume concentration (PVC) is not straightforward, as it depends not only on the cost of TiO2 but also on the cost of other ingredients such as resin and extender, and on the relationship between TiO2 scattering power and paint composition. While it seems sensible that the most cost-effective paint would have the least amount TiO2, it is in fact the case that too little TiO2 can result in a higher cost of coverage, just as too much TiO2 can. In this chapter, we detail methods for determining the most cost-effective TiO2 concentration in various types of paints. |
