Multi-layer sheet having a weatherable surface layer

摘要

A multi-layer sheet and a process for producing the sheet are disclosed. The sheet can comprise a first polymer layer comprising a film of polyvinyl fluoride (PVF) or polyvinylidene fluoride (PVDF) having an adhesive coating on one side; second optionally pigmented polymer layer extruded onto the adhesive coating of the first polymer layer; and optionally a third polymer layer. Also a photovoltaic module comprising a prebonded backskin that comprises the multi-layer sheet.
