Abstract: The present technology provides a coating system including an inorganic UV-absorbing material and a catalyst. The inorganic UV-absorbing material is chosen from cerium oxide, titanium oxide, zinc oxide, or combinations of two or more thereof. The inorganic material may be provided ranging from 1 wt. % to about 50 wt. % based on the dry weight of film after curing the coating system. The catalyst is provided in an amount ranging from 1 ppm to about 75 ppm. The coating system may include a topcoat material, a primer material, or a combination thereof.

Abstract: A primer composition comprising metal oxide particles modified with an alkyltrialkoxy silane; an organic polymer; and a solvent. The weight ratio of alkyltrialkoxy silane to metal particles is at least 0.9:1. The primer compositions produce films having excellent optical and adhesion characteristics.
