NOVELTY - The multilayer protective tape comprises a protective top layer comprising a polymer film, and an adhesive bottom layer. The top layer has a continuous surface (S) that is outwardly curved such that the tape has a symmetric or non symmetric cross-sectional profile having an inner section between two lateral sections. The inner section has a thickness (400-5000 mu m) (Ti) made up by a thickness of the top layer and the adhesive bottom layer that is greater than the thickness of one of the lateral sections (T1, T2) made up by the thickness of the top layer and adhesive bottom layer.    USE - The multilayer protective tape is useful for protecting a rotor blade of a wind turbine from erosion (claimed).    ADVANTAGE - The multilayer protective tape exhibits high impact dampening properties, increased elasticity, and uniform thickness, and protects the rotor blade of the wind turbine from harsher erosion conditions thus increasing the life span of the rotor blade of the wind turbine.    DETAILED DESCRIPTION - The multilayer protective tape comprises a protective top layer comprising a polymer film, and an adhesive bottom layer. The top layer has a continuous surface (S) that is outwardly curved such that the tape has a symmetric or non symmetric cross-sectional profile having an inner section between two lateral sections. The inner section has a thickness (400-5000 mu m) (Ti) made up by a thickness of the top layer and the adhesive bottom layer that is greater than the thickness of one of the lateral sections (T1, T2) made up by the thickness of the top layer and adhesive bottom layer. The thickness of lateral section is 0-350 mu m. The inner section comprises 0-95% of a width (W) of the tape. The adhesive bottom layer: has an upper surface facing the top layer, and a bottom surface that is opposite to the upper surface and is patterned to comprise grooves or dots; comprises, across its thickness, adhesive layers of which one adhesive layer comprises a foam adhesive; and is prepared by a wet-in-wet coating process. The top layer has a uniform thickness. The adhesive layer further comprises an acrylic adhesive. INDEPENDENT CLAIMS are included for:    (1) a method for protecting a rotor blade of a wind turbine from erosion;    (2) a rotor blade; and    (3) a process for forming a multilayer tape.
