Abstract: Coating compositions comprising a polymer binder and a sphere selected from porous metal oxide spheres formed from metal oxide particles and having, e.g., an average porosity of from 0.10 to 0.90; polymer spheres formed from a multimodal distribution of polymer particles; or mixtures thereof, are described herein. The sphere enhances the reflective characteristics of the coating compositions with respect to electromagnetic radiation. In particular, the coating compositions when dried, can exhibit UV reflectance, visible light reflectance, IR reflectance, or a combination thereof.

Abstract: Disclosed in certain embodiments are closed-cell metal oxide particles and methods of preparing the same. In at least one embodiment, a closed-cell metal oxide particle comprises a metal oxide matrix defining an array of closed-cells. Each closed-cell encapsulates a media-inaccessible void volume. The outer surface of the closed-cell metal oxide particle is defined by the array of closed-cells.
