Definitions
- the present invention relates to a curable resin composition.
- a curable resin composition For example, a photocurable or room temperature curable fluoropolymer that exhibits high adhesion to fluoropolymers, and has a high heat resistance and light resistance, an adhesive composition using the same, and coating or bonding thereby Further, the present invention relates to a back sheet and a front sheet for solar cells in which each film layer is bonded with the adhesive composition.
- back sheet has (a) a fluorine-based film on the surface in order to provide durability (degradation resistance for outdoor use) and barrier properties (water vapor and gas barrier).
