Abstract: The present disclosure provides an extrudable article and a composition, each including at least one polyurethane including hydroxyl groups and latent isocyanate groups in the form of uretdione groups. The hydroxyl groups are present on a first polyurethane and the latent isocyanate groups are present on either the first polyurethane or a second polyurethane and a ratio of the latent isocyanate groups to the hydroxyl groups is greater than 1.2:1. A method of making the extrudable article is provided including reacting in an extruder a polymerizable composition including a uretdione-containing material including a reaction product of a diisocyanate reacted with itself, a hydroxyl-containing compound, and an isocyanate-containing compound. A method of making a core-sheath filament is provided including forming a core composition of the at least one polyurethane and wrapping a sheath composition including an ethylene copolymer or a polyolefin around the core composition. Further, methods of printing a composition are provided including heating and mixing the extrudable article, such as in an extruder, to form a molten composition, then dispensing the molten composition through a nozzle onto a substrate.

Abstract: Provided is a surfacing film that includes a plurality of layers. The layers include a first clear coat layer made from a crosslinked polyurethane that is a reaction product of a reactive mixture including an isocyanate and a polyol containing a styrene repeat unit and a hydroxyl-containing (meth)acrylate repeat unit. The surfacing film further includes a bulk layer made from a thermoplastic polyurethane and an adhesive layer. Optionally, the surfacing film includes second clear coat layer, which can be made from a polyurethane that is at least partially crosslinked. The resulting surfacing film can display high stain resistance, high peel strength, superior scratch resistance and self-healing properties.
