The present disclosure provides a tape comprising: a) a single layer comprising a crosslinked polymer, selected from the group consisting of crosslinked polyurethane, crosslinked polyurea, and crosslinked mixed polyurethane/polyurea polymer, and b) an adhesive layer. In another embodiment, the disclosure provides an erosion resistant construction comprising, first, an element of an aircraft comprising: an aircraft skin segment having an external surface, and a deicing mechanism associated with said aircraft skin segment capable of heating said external surface to temperatures in excess of 65° C.; and, second, a tape comprising: at least one layer comprising a crosslinked elastomeric polymer, which may be a crosslinked polymer selected from the group consisting of crosslinked polyurethane, crosslinked polyurea, and crosslinked mixed polyurethane/polyurea polymer, and an adhesive layer; wherein the tape is bonded to the external surface of the aircraft skin segment by the adhesive layer. In another embodiment, the tape comprises at least one layer comprising a semi-interpenetrating polymer network of a crosslinked acrylate and an uncrosslinked polymer selected from the group consisting of polyurethane, polyurea, and mixed polyurethane/polyurea polymer.

1. An erosion resistant construction comprising: a) an element of an aircraft comprising: i) an aircraft skin segment having an external surface, andii) a deicing mechanism associated with said aircraft skin segment capable of heating said external surface to temperatures in excess of 65° C.;b) a tape comprising: i) at least one layer comprising a semi-interpenetrating polymer network comprising a crosslinked acrylic polymer and an uncrosslinked polymer, selected from the group consisting of polyurethane, polyurea, and mixed polyurethane/polyurea polymer, andii) an adhesive layer; wherein the tape is bonded to the external surface of the aircraft skin segment by the adhesive layer. 2. The construction according to claim 1 wherein the tape comprises no polymer layer, other than the adhesive layer, that does not contain crosslinked polymer. 3. The construction according to claim 1 wherein the uncrosslinked polymer is a polyurethane. 4. The construction according to claim 1 wherein the uncrosslinked polymer is a polyurea. 5. The construction according to claim 1 wherein said at least one layer is a single layer consisting essentially of a semi-interpenetrating polymer network comprising a crosslinked acrylic polymer and an uncrosslinked polymer, selected from the group consisting of polyurethane, polyurea, and mixed polyurethane/polyurea polymer. 6. The construction according to claim 5 wherein said uncrosslinked polymer is a polyurethane. 7. The construction according to claim 5 wherein said uncrosslinked polymer is a polyurea. 8. The construction according to claim 1 wherein the external surface of the aircraft skin segment includes one or more layers of paint and/or primer.
