    • 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 degradation 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.
    • 本发明的含氟聚合物组合物通常包含含有一种或多种含氟聚合物的组分,紫外线防护组分(以下称为UV保护组分),以及任选的一种或多种另外的组分。 UV保护组分包括至少一种具有一定结构和重均分子量至少为1000的受阻叔胺(HTA)化合物的组合。该叔胺与至少一种有机的UV光吸收化合物 (UVLA化合物)。当根据本发明的原理选择HTA化合物和UVLA化合物时,UV保护组分提供具有显着改善的耐候性特征的含氟聚合物组合物,用于保护下面的材料,特征 ,结构,部件和/或类似物。 特别地,结合本发明的UV保护组分的含氟聚合物组合物意外地改善了抗紫外线可能引起的黑化,着色或其它降解的能力。 因此,预期受这些组合物保护的装置将有显着改善的使用寿命。 该组合物具有广泛的用途,但特别适用于在光电器件中形成保护层。
