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: The present disclosure relates to abrasive articles including conformable coatings, e.g. a hydrophilic coating, and polishing systems therefrom. The present disclosure provides an abrasive article including a ceramic body having an abrading surface and an opposed second surface, wherein the abrading surface of the ceramic body includes a plurality of engineered features each having a base and a distal end opposite the base and the ceramic body has a Mohs hardness of at least 7.5; a conformable metal oxide coating adjacent to and conforming to the plurality of engineered features, wherein the conformable metal oxide coating includes a first surface; and a conformable polar organic-metallic coating in contact with the first surface of the conformable metal oxide coating, wherein the conformable polar organic-metallic coating includes a chemical compound having at least one metal and an organic moiety having at least one polar functional group.

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.
