An abrasive article having a removable support sheet having a first major surface. An image layer containing inks applied over the first major surface. A polyurethane backing layer having a first major backing surface located adjacent to the image layer and a second major backing surface opposite the first major surface. A functional layer comprising an abrasive layer applied to the second major surface; the abrasive layer comprising a make coat, abrasive particles and a size coat.

Flexible abrasive article with image layer

A nanostructured article includes a substrate; a plurality of first nanostructures disposed on, and extending away from, the substrate; and a covalently crosslinked fluorinated polymeric layer disposed on the plurality of first nanostructures. The plurality of first nanostructures includes polyurethane. The polymeric layer at least partially fills spaces between the first nanostructures to an average minimum height above the substrate of at least 30 nm such that the polymeric layer has a nanostructured surface defined by, and facing away from, the plurality of first nanostructures.

Nanostructured article

An abrasive article includes backing material, binder comprising an anionic water solubilizing material provided on at least a portion of the backing material and abrasive particles provided on at least a portion of the backing material. A method of making such an abrasive article comprises the steps of providing a backing material, applying a first binder containing an anionic water solubilizing material to the backing material, and applying abrasive particles to the backing material.

Abrasive article with anionic water solubilizing material and method of making

Presently describes are articles, such as liquid reservoirs, comprising a liquid repellent surface. The liquid repellent surface comprises a surface layer comprising a silane or siloxane material, wherein the liquid repellent surface is not a lubricant impregnated surface. In one embodiment, the liquid repellent surface (e.g. layer) comprise a silicone melt additive and a thermoplastic polymeric material component. In some embodiments, the article (e.g. liquid reservoir) comprise a thermoplastic polymeric material.

Liquid reservoirs and articles comprising a repellent surface comprising a siloxane material

The compositions include a methylated siloxane liquid and a solvent comprising at least one of a ketone or ester each having up to six carbon atoms, a halogenated alkane having up to two carbon atoms, tetrachloroethene, 1-chloro-4-trifluoromethyl benzene, or ethane. The compositions can also include hydrocarbon solvent comprising at least one of toluene, xylene, or a saturated hydrocarbon represented by formula CH, wherein x is from 5 to 8, and wherein y is 0 or 2 and/or propellant. The method can include applying the composition to a brake system component to clean the brake system component. The method can also include applying a composition including hexamethyldisiloxane to a brake system component to clean the brake system component.

A method of making a silyl-terminated polyurethane in an aqueous dispersion aqueous silyl-terminated polyurethane dispersions are described. In one embodiment, the polyurethane comprises a) urethane moieties derived from the reaction of a (i) a diol; (ii) a neutralized anionic water solubilizing compound; and iii) a diisocyanate. The polyurethane also comprises b) silyl terminal groups derived from an alkoxy silane compound having the formula (RO)SiR&#x2014;Z, wherein Ris independently hydrogen or a C-Calkyl; Ris a divalent group selected from alkylene, alkylarylene, oxyalkylene; and Z is selected from the group consisting of &#x2014;OH, &#x2014;SH, &#x2014;NR, &#x2014;NH, wherein R is an aromatic or aliphatic cyclic group. The polyurethane also comprises c) urea moieties derived from the reaction of an isocyanate terminated prepolymer and a difunctional hydrazine or hydrazide compound.

Polyurethane-polyurea dispersions comprising hydrazine or hydrazide chain extenders

Provided are one-part, shelf-stable polyurethane aerosol compositions, and related articles and methods. When sprayed onto a substrate and dried, these compositions provide polyurethane films. These polyurethane films display improved moisture resistance, optical clarity, and weatherability compared to known aerosol compositions, particularly in adverse environmental conditions. The compositions generally include an aqueous polyurethane dispersion containing a urethane moiety obtained by reacting (i) a polyol or thiol having isocyanate-reactive functional groups, (ii) a neutralized water-solubilizing compound, and (iii) a diisocyanate and optionally a silane terminal group; a propellant; and optionally one or more additives.
