Abstract: An airfoil is provided that includes an exterior substrate surface, and a coating layer adjacent to the exterior substrate surface. The coating layer has an icephobic coating composition that includes a first polymer, a second polymer that is a fluoropolymer, an isocyanate, and a curative. The coating layer is bonded to the airfoil via an intermediate adhesive layer. The coating layer has a bottom surface, and at least one of the exterior substrate surface and the bottom surface has an RMS surface roughness of at least about 1 micron or greater before the coating layer is bonded to the exterior substrate surface.
