Ti-Pure™ R-931 is a pigment with an excellent balance of hiding power and film integrity in emulsion and solvent flat paints. It is most efficient in coatings of 45–60 PVC with TiO2 loading of 2 lb/gal (0.24 kg/L) or higher. The surface oxide treatment provides optical spacing in crowded systems, so that TiO2 efficiency is maximized while maintaining the highest level of film integrity.
