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

Various embodiments disclosed relate to an abrasive sheet. The abrasive sheet includes a first layer including an abrasive major surface and an opposite second layer defining a second major surface. The second major surface includes a plurality of protrusions extending outwardly from the second major surface. The protrusions include a first polymer component having at least one of a Shore A hardness ranging from about 5 to about 100 and a Shore D hardness ranging from about 1 to about 70. The first layer and the second layer are directly joined to each other.

Abrasive sheet including a plurality of protrusions

An abrasive article is provided that has a backing having opposed first and second major surfaces, an abrasive layer disposed on the first major surface, and a plurality of protrusions extending outwardly from the second major surface. The protrusions comprise a polymer having a Shore A hardness ranging from 5 to 90. These articles provide an alternative sanding solution enabling abrasive articles lacking an attachment layer to be handled effectively and efficiently, providing for a technically superior abrasive sheet on the marketplace that does not use or require an attachment layer.

Abrasive articles, assemblies, and methods with gripping material

Provided are abrasive articles that include a plurality of layers, in the following order: a backing; an abrasive layer; and a supersize coat. The supersize coat contains a metal salt of a long-chain fatty acid and clay particles dispersed therein. Advantageously, the clay particles enhance the optical clarity of the supersize coat, allowing printed abrasive articles to be made with thicker supersize coatings. The addition of clay was also found to improve cut performance of the abrasive article relative to articles in which the clay particles are absent.

Abrasive articles and related methods

An abrasive article is provided which comprises a plurality of layers in the following order: a backing; an abrasive layer; a primer layer comprising clay particles, wherein the clay particles are agglomerated and form a layer; and a supersize coat comprising a metal salt of a long-chain fatty acid. The addition of the aforementioned primer layer can significantly reduce loading of swarf and improve both the cut and expected lifetime of the abrasive article.

Abrasive article

An apparatus can comprise a body and a first portion. The first portion can be coupled to the body and moveable therewith. The first portion can comprise a rigidifying material and a layer. The rigidifying material can be positioned in a chamber defined by an envelope formed of a gas-impermeable material. A pressure within the chamber can be variable between at least a lower pressure state and a higher pressure state. In the higher pressure state the material is relatively flexible, and in the lower pressure state the material can be relatively less flexible than in the higher pressure state. The layer can be manipulatable by the rigidifying material. More particularly, the layer can have a first state when the pressure within the chamber is in the higher pressure state. In the first state, the layer can be formable by the target surface to take on a desired shape that can be substantially a match of the target surface. The layer can have a second state when the pressure within the chamber is in the lower pressure state. In the second state, the layer can maintain the desired shape and can be substantially less formable than in the first state.

Shape-formable apparatus

A method of providing an easy-clean, water-sheeting coating on a substrate includes: abrading a surface of a substrate using an abrasive article to provide an abraded surface having a surface roughness R?a#191 in a range of from 100 nm to 3500 nm, contacting a coatable composition with the abraded surface, and removing water from the coatable composition. The coatable composition comprises silica nanoparticles and has a pH of 7.5 or less. A kit including the abrasive article and the coatable composition is also disclosed.

A flexible abrasive article is provided with a first, non-tacky base layer having opposed first and second major surfaces. An ink layer is disposed on the first major surface of the first base layer, while a second, thermoplastic base layer is disposed on the ink layer whereby the ink layer is located between the first and second base layers. Disposed on the second base layer is an abrasive layer such that the second base layer is located between the abrasive layer and the ink layer. Compared with conventional printed flexible adhesive articles, the provided articles improved robustness while avoiding manufacturing difficulties related to flexographic printing onto abrasive coated articles.

Printed abrasive article

Provided are abrasive articles in which the make layer, abrasive particle layer, and size layer are coated onto a backing according to a coating pattern characterized by a plurality of discrete islands. The coating pattern has features in which all three components are generally in registration with each other, while providing a pervasive uncoated area extending across the backing. Advantageously, this configuration provides a coated abrasive that displays superior curl-resistance compared with previously disclosed abrasive articles. Moreover, this configuration resists loading, resists de-lamination, has enhanced flexibility, and decreases the quantity of raw materials required to achieve the same level of performance as conventional abrasive articles.

Coated abrasive article and method of making the same

Provided are abrasive articles having a plurality of elongated channels extending across its working surface and intersecting with each other. These channels provide hinge points that enhance flexibility of the article along two or more directions. Optionally, the abrasive article includes a flexible attachment layer, along with apertures that penetrate through the attachment layer located at the intersection points of the channels. The enhanced flexibility allows the abrasive article to easily access recessed areas of the workpiece and facilitates applying even pressure across convex and concave surfaces. The channels assist in segregating dust particles from the abrading operation, and the optional apertures can be advantageously connected to a vacuum source for evacuation of the dust particles from the channels.

Flexible abrasive article and methods of making

A structured abrasive article includes a backing having a structured abrasive layer disposed on and secured thereto. The structured abrasive layer includes shaped abrasive composites that comprise abrasive particles and nonionic polyether surfactant dispersed in a crosslinked polymeric binder. The abrasive particles have a mean particle size of less than 10 micrometers. The nonionic polyether surfactant is not covalently bound to the crosslinked polymeric binder and is present in an amount of from 2.5 to 3.2 percent by weight based on a total weight of the shaped abrasive composites. The structured abrasive articles are useful for abrading a workpiece.

A microstructured antimicrobial film, an antimicrobial film assembly, a method of protecting a surface from microbial contamination, and a method of making a microstructured antimicrobial film. The microstructured antimicrobial film can include a substrate having a first side that includes a first major surface, a plurality of microstructured wells defined in the first side of the substrate, and an antimicrobial material positioned within at least some of the plurality of wells. Each of the plurality of wells can be at least partially defined by a base that is spaced a distance from the first major surface of the substrate. The antimicrobial material can be positioned, such that an upper surface of the antimicrobial material is spaced a distance from the first major surface of the substrate. The antimicrobial film assembly can include a roll or a stack of microstructured antimicrobial films.

Microstructured antimicrobial film

An adhesive blend includes a pressure sensitive adhesive and non-tacky microspheres that function as a detackifier. The non-tacky microspheres are solid, elastomeric, non-crushable, and solvent insoluble. The non-tacky microspheres are a reaction product of at alkyl (meth)acrylate monomers having from 1 to 14 carbon atoms, multifunctional (meth)acrylate and or multifunctional vinyl crosslinker, initiator, and polymeric stabilizer. The blend can be coated onto a sheet to form a pad, such as an easel pad.

Adhesive composition having non-tacky microspheres and sheets made therefrom

The present invention is directed to an adhesive article and methods of manufacturing the adhesive article. The adhesive article comprising at least one major surface comprising a microstructured surface, the microstructured surface comprising microstructured elements, the microstructured elements comprising walls and at least one wall has variable height with a maximum height and a minimum height along the wall length.
