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: 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: Adhesive compositions that are optically transparent include a (meth)acrylate-based copolymer having a refractive index of at least 1.48, and particles of a thermoplastic polymer. At least some of the particles have an average particle size that is larger than the wavelength of visible light. The adhesive compositions are prepared by hot melt processing packaged adhesive compositions.
