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.

The present invention is an adhesive composition that is characterized by containing (A) a modified polyolefin resin and (B) an epoxy compound, and is also characterized in that: the modified polyolefin resin (A) is obtained by graft modifying a polyolefin resin with use of a modifying agent that contains an ,-unsaturated carboxylic acid or a derivative thereof; the content of the epoxy compound (B) is 1-20 parts by mass relative to 100 parts by mass of the modified polyolefin resin (A); and the epoxy compound is composed of two or more types of epoxy compounds.

A composition according to the present invention contains 100 parts by mass of a component (A) and 1-200 parts by mass of a component (B) and is solid at 25 C., the solid form being achieved at 25 C. without spray drying, impregnation into wax, or the like, and said composition is useful as an additive for a paint composition and an adhesive composition. The component (A) is an organic silicon compound represented by general formula (1), and the component (B) is at least one of organic silicon compounds represented by general formulas (2) and (3)
