Abstract:

TiO2 is typically the most expensive and one of the highest carbon footprint components of an emulsion paint formulation. This paper highlights the study to understand the role of a polymer emulsion in improving hiding power of a flat paint formulation. By using polymer emulsions that are specifically designed to interact with the pigment particles, optimal dispersion of TiO2 pigment in the paint film is obtained. As a result, the scattering efficiency of each individual particle is maximized resulting in improved hiding. This technology platform now gives manufacturers/formulators more flexibility to provide “Greener” solution to either reduce formulated paint cost by decreasing TiO2 loading to match existing tint strength or use it to improve hiding power of existing paint formulations.
