An adhesive layer can include a polymer blend of a first polymer and a second polymer. In an embodiment, the first polymer can be a modified fluoropolymer. In another embodiment, the second can be a non-fluorinated polymer. In a particular embodiment, the adhesive layer can include greater than 60 wt. % of the first polymer for the total weight of the polymer blend. A bearing can include the adhesive layer disposed over a substrate.
