Abstract

The fluoropolymer compositions of the present invention generally incorporate ingredients comprising one or more fluoropolymers, an ultraviolet light protection component (hereinafter UV protection component), and optionally one or more additional ingredients if desired. The UV protection component includes a combination of at least one hindered tertiary amine (HTA) compound having a certain structure and a weight average molecular weight of at least 1000. This tertiary amine is used in combination with at least one organic, UV light absorbing compound (UVLA compound) having a weight average molecular weight greater than 500. When the HTA compound and the UVLA compound are selected according to principles of the present invention, the UV protection component provides fluoropolymer compositions with significantly improved weatherability characteristics for protecting underlying materials, features, structures, components, and/or the like. In particular, fluoropolymer compositions incorporating the UV protection component of the present invention have unexpectedly improved ability to resist blackening, coloration, or other de gradation that may be caused by UV exposure. As a consequence, devices protected by these compositions would be expected to have dramatically improved service life. The compositions have a wide range of uses but are particularly useful for forming protective layers in optoelectronic devices.

Protective coating compositions and devices

Patent Pickett, James Edward

In one aspect of the present invention, a UV-protective coating composition is described. The UV protective coating composition includes an acrylate polymer; and a non-crystallizing UV-absorber composition. The non-crystallizing UV absorber composition includes a dibenzoylresorcinol and at least one triazine compound. The dibenzoylresorcinol is present at a level in the range of from about 10 weight percent to about 25 weight percent, based on the total weight of the coating composition. Also provided is an article that includes the UV protective coating composition, and a method to protect the article.
