STABLE PRIMER FORMULATIONS AND COATINGS WITH NANO DISPERSION OF MODIFIED METAL OXIDES

摘要

The present invention is directed to a primer composition, comprising: (a) metal oxide nanoparticles surface-modified with an organofunctional silane moiety having a specific functionality, (b) an organic polymer; and (c) one or more solvents; wherein the composition comprises less than 4 wt % of water, based on the total weight of said primer composition. The composition produces films having excellent optical and adhesion characteristics, and excellent weatherability and thermal stability.
