The present disclosure provides abrasive articles that include an abrasive layer having a contact surface, a first layer coupled to the abrasive layer, and a second layer coupled to the first layer. The first layer is configured to provide contact pressure to the abrasive layer, such as through a higher hardness than the second layer. The second layer is configured to provide conformability to the abrasive layer, such as through a higher compressibility than the first layer. The resulting abrasive articles may exert a consistent contact pressure against a substrate with increased conformability around the substrate, reduced hysteresis, improved removal rate consistency, and/or improved lifetime over abrasive articles that do not use the multiple layer construction described above.

Conformable abrasive article

An abrasive rotary tool includes a tool shank defining an axis of rotation for the rotary tool, and an abrasive external working surface. The abrasive external working surface includes a resin, and a plurality of porous ceramic abrasive composites dispersed in the resin, the porous ceramic abrasive composites including individual abrasive particles dispersed in a porous ceramic matrix. At least a portion of the porous ceramic matrix comprises glassy ceramic material. A ratio of the average porous ceramic abrasive composite size to the average individual abrasive particle size is no greater than 15 to 1.

Abrasive rotary tool with abrasive agglomerates

An abrasive rotary tool includes a tool shank a flexible planar section positioned opposite the tool shank. The flexible planar section forms a first abrasive external surface on a first side of the flexible planar section and a second abrasive external surface on a second side of the flexible planar section. The flexible planar section facilitates abrading, corners of a workpiece across multiple angles relative to the axis of rotation for the rotary tool through bending of the flexible planar section when the abrasive external surfaces are applied to a corner of the workpiece.

Flexible abrasive rotary tool

A method of forming a recess in a surface of a substrate includes: providing an abrasive article comprising a structured abrasive member disposed along a peripheral surface of a support member, frictionally contacting the structured abrasive layer with a surface of a substrate, longitudinally advancing the structured abrasive layer relative to the surface of the substrate; and rotating at least one of the abrasive article or the substrate relative to the other around a rotational axis perpendicular to the surface of the substrate such that the structured abrasive layer maintains contact with and abrades the surface of the substrate. The structured abrasive member comprises a structured abrasive layer comprising shaped abrasive composites secured to a backing, wherein the backing is proximate to the support member. The shaped abrasive composites comprise abrasive particles retained in a binder material. The present disclosure also provides an abrasive wheel comprises a structured abrasive member disposed on a peripheral surface of a support wheel and display covers including a spherically concave recess abutting a cylindrical passage.

Transparent ink-jet recording films, compositions, and methods are disclosed. These films can exhibit high maximum optical densities, rapid ink drying, low curl, excellent adhesion between the coating layers and the substrate, and negligible ink transfer between stacked ink-jet recording films after imaging. Such films are useful in medical imaging applications.

Transparent ink-jet recording films, compositions, and methods

The compositions and methods of the present application can provide transparent ink-jet recording films that may be used by printers relying on optical detection of fed media. Such films can be useful for medical image reproduction.

A direct thermographic material has one or more thermographic layers comprising a film-forming polymer binder on a polymeric support. Disposed between the polymeric support and the one or more thermographic layers is a non-light sensitive adhesive layer comprising one or more polyisocyanate crosslinked hydrophobic polymer binders.

Direct thermographic materials with crosslinked carrier layer

A direct thermographic material has one or more thermographic layers comprising a film-forming polymer binder on a polymeric support. The binder for at least one thermographic layer comprises a hydrophobic, organic soluble binder that is a polyvinyl acetal having a degree of polymerization greater than 650 and less than 2500.
