Enlightened TiO2 -scattering, bound by a better binder

 
In coatings the improved utilization of TiO2 benefits the consumer, producer, as well as the environment. Herein we report the development of a surface modified styrene acrylate binder which enables excellent TiO2-efficiency in decorative coating formulations. Advanced analytical techniques like Confocal Laser Scanning Microscopy (CLSM) and Small Angle X-ray Scattering (SAXS) were used to study decorative coating formulations from the wet stage, during drying into the dry coating. The TiO2 distribution was quantified by both latter methods, which correlate very well with scattering coefficients and spreading rates. These studies allowed the identification of effective surface modifications of polymeric binders to improve the distribution of TiO2 in coatings
