Abstract: Articles are described comprising a surface layer comprising at least one long hydrocarbon chain silane compound (C8-C36) bonded to a siliceous layer such as diamond-like glass. In an embodiment, the siliceous layer has a porosity of no greater than 10% and a thickness no greater than 1 micron. In another embodiment, the siliceous layer comprises 10-50 atomic percent carbon and the article further comprises an organic polymeric base member or a hardcoat layer. Also described are coating compositions comprising at least one C8-C17 hydrocarbon silane compound and at least one C18-C36 hydrosilane compound.

Abstract: Various embodiments disclosed relate to a surfacing film. The surfacing film includes a base layer. The base layer includes a thermoplastic polyurethane film comprising a reaction product of a reaction mixture of a diisocyanate, a polyester polyol having a melting temperature of at least about 30° C.; and a diol chain extender. There are many reasons to use the surfacing film including easier and more cost effective manufacturing of the surfacing film by directly extruding the base layer by mixing the reaction mixture in an extruder. Another reason to use the surfacing film is that the film has improved resistance to discoloration. Another reason to use the film is that the film shows good toughness.

Abstract: Multilayer barrier coatings or films and methods of making the same are provided. The coatings or films include a hardcoat layer (122) including nanoparticles hosted by a binder, and a barrier layer (124) directly disposed on a major surface (122s) of the hardcoat layer (122). The binder includes one or more silicone (meth)acrylate additives.

Abstract: A method of coating a microneedle array by applying a coating fluid using a flexible film in a brush-like manner. A method of coating a microneedle array comprising: providing a microneedle array having a substrate and a plurality of microneedles; providing a flexible film; providing a coating solution comprising a carrier fluid and a coating material; applying the coating solution onto a first major surface of the flexible film; performing a transfer step of bringing the first major surface of the flexible film into contact with the microneedles and removing the flexible film from contact with the microneedles; and allowing the carrier fluid to evaporate.
