Abstract
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 consisti…
