Abstract: Disclosed herein are hard coat compositions and composite films including a thermoplastic polyurethane. A hard coat composition includes a thermoplastic polyurethane having a hard segment content of 80 percent by weight or greater. The thermoplastic polyurethane is a reaction product of a) a diisocyanate; b) a polyol optionally comprising a cyclic structure; and c) a chain extender. At least one of the polyol or the chain extender comprises at least one side chain and at least one of the diisocyanate or the chain extender comprises a cyclic structure. A composite film includes 1) a hard coat layer having opposing first and second major surfaces; and 2) a second layer disposed on at least a portion of the hard coat layer. These materials can serve decorative and/or protective functions while displaying both good elongation at moderate temperatures and high hardness.

Abstract: Provided compositions, films, and methods impart a low-surface energy surface to a polyurethane layer whereby contaminants to bead up on the surface to dramatically facilitate removal. At the same time, the provided articles retain excellent clarity and processibility for use in surface protection applications. Compositions having these advantageous properties derive from reacting a primary polyisocyanate; a monohydroxyl polydimethylsiloxane present in a suitable amount; and a polyol selected from the group consisting of: a caprolactone polyol, polycarbonate polyol, a polyester polyol, acrylic polyol, polyether polyol, polyolefin polyol, and mixtures thereof.

Abstract: Disclosed herein are improved thermoplastic polyurethane compositions, articles, and related methods. These compositions include aliphatic thermoplastic polyurethanes having a hard segment content ranging from 57 percent to 80 percent by weight. The hard coat compositions have a Shore D hardness of at least 70 and can display an Elongation at Break test result at 25 degrees Celsius of at least 150 percent. These materials, when hardened, can serve decorative and/or protective functions while displaying both a high degree of elongation at moderate temperatures and high hardness.

Abstract: A multilayer protective film comprising a first layer, a second layer and a PSA layer. The first layer at least comprises a polyester-based polyurethane, a polycarbonate-based polyurethane or a combination or blend of both. The second layer at least comprises a polycaprolactone-based thermoplastic polyurethane. The PSA layer comprises a pressure sensitive adhesive. One major surface of the first layer is bonded to one major surface of the second layer, and the PSA layer is bonded to an opposite major surface of the second layer such that the second layer is sandwiched between the first layer and the PSA layer.
