VernisIndex. décimale : 667.9 Revêtements et enduits Résumé : Recent health and environmental concerns within the European coating industry have forced formulators and manufacturers to shift from solventborne to waterborne systems over the last decade. Now, one of the newer challenges for the coatings industry is the demand for more sustainable, eco-friendly, energy efficient and greener technology.

Transfert radiatifIndex. décimale : 667.9 Revêtements et enduits Résumé : We present an extensive theoretical study of the optical properties of hollow polymer particles (HPP) dispersed into a polymer resin as functions of their structure and volume-filling fraction. We show that a dependent light scattering model predicts the occurrence of three different light propagation regimes, the existence of which is consistent with experimental data gathered in the literature. We then analyze the effect of the polymer shell thickness on the magnitude of the near-field and far-field dependent light scattering phenomena. We also discuss and compare the variation of the scattering efficiency of Ropaqueâ„¢, measured in our laboratory, as a function of the pigment volume-filling fraction, with dependent light scattering model. In particular, we show that in the case of HPP, quasi-linear variation of the scattering efficiency as a function of the particle volume-filling fraction is not an undeniable indication of the absence of electromagnetic couplings in the system. Finally, we used a solution of the radiative transfer equation to compare the prediction of the opacity of several simple paint films when a dependent light scattering model is used instead of the independent scattering approximation to calculate the optical properties of the films at a local scale.

Opacité (optique)Index. décimale : 667.9 Revêtements et enduits Résumé : For those who have been in the coatings industry long enough, the rollercoaster ride of TiO2 price comes as no surprise. That said, the day of an even 10-year cycle in price have changed to shorter periods of high price (often painfully high) followed by longer periods of relatively low price (painfull for the suppliers). Even when relatively "cheap", TiO2 continues to be one of the most expensive raw materials in a coating, so ensuring that the pigment is used correctly and efficiently remains a crucial busines objective.
