Abstract: Articles are described comprising a substrate and a hardcoat layer disposed on the substrate. The hardcoat layer comprises the hydrolyzed and condensed reaction product of a composition comprising: i) first hydrophobic silane monomer(s) having the formula R1Si(OR)3 wherein R and R1 is methyl or ethyl; ii) optional second silane monomer(s) having the formula (R2)4-mSi(OR)m or Si(OR)4, wherein R, R1 and R2 are organic groups with the proviso that R1 is not methyl or ethyl and m ranges from 1 to 3. The hardcoat layer N may further comprises 10 to 30 wt. % silica nanoparticles. A surface layer comprising a hydrophilic silane may be disposed on the hardcoat layer. Also described is a method of using an article having a rewritable surface, hardcoat coating compositions, and methods of making hardcoat compositions and articles.

Abstract: A fluoropolymer coating composition is described comprising an aqueous liquid medium, fluoropolymer particles dispersed in the aqueous liquid medium, and at least one aziridine compound. The aziridine compound comprises at least two aziridine groups (i.e. polyaziridine) or at least one aziridine group and at least one alkoxy silane group. In another embodiment, an article is described comprising a substrate wherein a surface of the substrate comprises a coating comprising fluoropolymer particles; and a reaction product of at least one aziridine compound comprising at least two aziridine groups or at least one aziridine group and at least one alkoxy silane group. The coating can be utilized as a primer for bonding a non-fluorinated substrate to a fluoropolymer film and/or the coating can be used as an (e.g. outer exposed) surface layer. In some embodiments, the article may be the (e.g. backside) film of a photovoltaic module.

Abstract translation: 描述了一种氟聚合物涂料组合物，其包含水性液体介质，分散在水性液体介质中的含氟聚合物颗粒和至少一种氮丙啶化合物。 氮丙啶化合物包含至少两个氮丙啶基（即聚氮丙啶）或至少一个氮丙啶基和至少一个烷氧基硅烷基。 在另一个实施方案中，描述了包括基材的制品，其中基材的表面包含含有氟聚合物颗粒的涂层; 和至少一种包含至少两个氮丙啶基或至少一个氮丙啶基和至少一个烷氧基硅烷基的氮丙啶化合物的反应产物。 涂层可以用作将非氟化基底粘合到含氟聚合物膜上的底漆和/或涂层可以用作（例如外部暴露的）表面层。 在一些实施例中，制品可以是光伏模块的（例如背面）膜。
