Titanium dioxide has a substantial impact on the hiding performance of paint, which often leads to heavy usage during product formulation. However, performance comes at a cost because titanium dioxide is often the most expensive and energy-intensive component of the paint product. Also, incremental scattering improvement decreases at high-TiO2 loading due to pigment crowding. In an effort to reduce this dependence, The Dow Chemical Co. has developed a new binder, called EVOQUE Pre-Composite Polymer Technology, which interacts with the surface of titanium dioxide to improve dispersal. Particles are forced into a more ordered distribution, improving the scattering efficiency at much lower loadings. Ordering leads to better hiding despite using 15% less weight-by-volume of titanium dioxide.
