A sheet-like abrasive article includes a resilient backing sheet having opposed major surfaces and a continuous abrasive sheet affixed to the backing sheet. The abrasive sheet includes an abrasive support layer with abrasive particles arranged thereon, thereby defining an abrasive surface. A sanding tool assembly including such a sheet-like abrasive article is also disclosed.

Laminated flexible resilient abrasive article

A deterrent apparatus having a non-conductive tubing having a length, an outer surface and an inner surface defining a lumen, and at least a first electrical conductor and a second electrical conductor present on the outer surface of the non-conductive tubing. A power source comprising a battery having a first terminal and a second terminal is connected to the conductors so that the first terminal is electrically connected to the first conductor and the second terminal is electrically connected to the second conductor. The deterrent apparatus is suitable for use on medical tubing or veterinary tubing, for example, to deter animals from chewing or biting at the tubing.

A flexible hand-held abrasive article includes a conformable backup pad having opposed major surfaces, a backing layer affixed to one surface of the backup pad, the backing layer containing a plurality of biaxially oriented openings, and abrasive particles arranged on the backing layer, thereby defining an abrasive surface. A method of making such an abrasive article is also disclosed. The abrasive article may also comprise a backing layer containing a plurality of biaxially oriented slits with abrasive particles arranged at least one surface of the backing layer.

An abrasive article includes a substrate having opposed first and second surfaces, a make coat on at least a portion of the first surface, abrasive mineral particles on at least a portion of the make coat to provide an abrasive surface and a size coat arranged over at least a portion of the abrasive surface, wherein the size coat has a Young's modulus of less than 100,000 psi.

Abrasive article

A resilient flexible abrasive article includes a continuous backing layer including a support layer coated with foam, the continuous backing layer having opposed major surfaces, at least one of the major surfaces including a three dimensional surface topography including raised and recessed regions, and wherein the raised and recess regions are at least partially coated with abrasive particles, thereby defining an abrasive surface.

Flexible abrasive article

A resilient hand-held abrasive article suitable, for example, for woodworking, includes a plurality of separated raised abrasive surfaces to allow the article to more effectively conform to a contoured surface. A method of making such an abrasive article is also disclosed.

The invention provides a flexible abrasive product comprising a flexible sheet-like substrate comprising a multiplicity of separated resilient bodies connected to each other in a generally planar array in a pattern which provides open spaces between adjacent connected bodies, each body having a first surface and an opposite second surface; and abrasive particles to cause at least the first surface to be an abrasive surface. A method of making the abrasive is provided by providing the substrate and providing abrasive particles to at least the first surface to provide an abrasive surface.

A resilient flexible sanding sponge including a foam backing layer having a layer of abrasive particles distributed along one of its major surfaces that are adhered together and to the backing layer by a layer of flexible adhesive material. That backing layer has about the same flexibility and conformability as the backing layers on prior art sanding sponges, while having a significantly higher tear strength than prior art sanding sponges. That high tear strength backing layer can either be (1) a layer of felted urethane foam; or (2) a layer of foam that encompasses a reinforcing material. When the backing layer is of felted urethane foam the layer of flexible adhesive material can have a major structurally sound portion below the surface along which the layer of abrasive particles is positioned and a minor portion adhering the abrasive particles along that surface to leave large portions of the abrasive particles projecting above the layer of adhesive material where they can effectively abrade a surface over which the sanding sponge is rubbed.

A resilient abrasive article includes a resilient elongatable substrate, abrasive particles adhesively bonded to the substrate with a flexible make coat, and a hard size coat applied over the abrasive particles and flexible make coat. The size coat provides an anti-loading layer which is applied thinly enough to prevent the size coat from cracking and tearing the substrate during use.

An abrasive article is formed from a lofty nonwoven abrasive pad and one or more abrasive sheets. In one embodiment, each sheet has an abrasive layer on its front side and a plurality of engagement stems on its back side. Enough of the engagement stems engage fibers on the surface of the nonwoven pad to affix the two components together for workpiece surface treatment. In another embodiment, the nonwoven pad has a slit therein, and each abrasive sheet has a portion thereof inserted into its respective slit to anchor the sheet to the pad. In this embodiment, each sheet has an abrasive layer on its front side but may have no stems on its back side. In either embodiment, the sheets are readily replaceable on the nonwoven pad, thus creating a very simple and versatile arrangement for varying the abrasive characteristics presented to the workpiece.

Multiple abrasive assembly and method

Abrasive foam articles and a method of manufacture of such articles are described. The articles of the invention comprise a flexible and resilient foam substrate having first and second major substrate surfaces, at least one of the surfaces having a plurality of open cells substantially across the substrate surface, the open cells having coatable surfaces defined by interconnected voids; and a plurality of abrasive particles adhered to said coatable surfaces of said open cells in a substantially uniform manner.

Composition comprising (a) susceptors having the capability of absorbing microwave energy, said susceptors comprising a particulate substrate substantially non-reflective of microwave energy and a coating capable of absorbing microwave energy, and (b) a matrix substantially non-reflective of microwave energy. Susceptors are typically particles having a thin-film coating thereon. The matrix typically comprises polymeric or ceramic materials that are stable at temperatures conventionally used in microwave cooking. The composition allows reuse of the susceptors, eliminates decline in heating rate, eliminates arcing, allows the heating rate to be controlled, allows overheating to be controlled, and allows formation of microwave heatable composite materials having very low metal content.
