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. |

1. A primer composition, comprising:
(a) metal oxide nanoparticles surface-modified with an organofunctional silane moiety, said organofunctional silane moiety having the structure of Formula I or II:wherein in Formula (I), R1 is
R1=or wherein R1 is a functional group-containing moiety; wherein each R is an alkyl group having from 1 to 12 carbon atoms; wherein each R2 and R5 is independently an alkyl group having from 1 to 4 carbon atoms or is —CO—CH3; wherein each R3, R4 and R6 is independently hydrogen or methyl; and, wherein x, y and z are each an integer independently selected from 1 to 50,
(b) an organic polymer; and (c) one or more solvents. |
