A polymer bond abrasive article is formed of a continuous photocured polymer matrix having abrasive particles retained therein. The photocured polymer matrix includes at least one of an optical brightener or a light absorber, and the polymer bond abrasive article has a three-dimensional shape. An abrasive tool includes the abrasive article affixed to a shaft or a pad. Further, a method of making the polymer bond abrasive article includes a) obtaining a photocurable composition liquid dispersion; b) selectively curing a portion of the photocurable composition; and repeating steps a) and b) to form the polymer bond abrasive article. The dispersion contains at least one photocurable component; abrasive particles; a photoinitiator; and at least one of an optical brightener or a light absorber.

Polymer bond abrasive articles including continuous polymer matrix, and methods of making same

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.

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.

A polishing system includes a first carrier assembly configured to receive and hold a substrate and a polishing pad. The polishing pad includes a top major surface and a bottom major surface positioned opposite the top major surface, and a plurality of polishing elements extending from the top major surface of the polishing pad. The system further includes a polishing solution disposed between the top surface of the polishing pad and the substrate. The polishing fluid includes a fluid component, and a plurality of ceramic abrasive composites dispersed in the fluid component, the ceramic abrasive composites including individual abrasive particles dispersed in a porous ceramic matrix. The system further includes a second carrier assembly configured to receive and hold the polishing pad. The system is configured such that the polishing pad is movable relative to the substrate to carry out a polishing operation.

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.

An apparatus for irradiating an article, particularly a multi-layer article, with electron beam radiation is provided. The apparatus contains a window having a short unit path length and allows for controlled irradiation of an article such that upper portions of the article receive significantly higher electron beam dosages than lower portions of the article. Such differential dosage allows for modification of an article comprising a coating composition that can be modified by electron beam irradiation on a substrate that is vulnerable to degradation from electron beam radiation. A method of irradiating an article with electron beams, and products manufactured using the apparatus and method of the invention, are also disclosed.

Disclosed is a method for making a substrate coated with an adhesive, comprising applying an electron beam modifiable adhesive layer onto a repeatably reusable transfer surface, irradiating the adhesive layer with an electron beam to chemically modify the adhesive layer, and transferring the irradiated adhesive layer to a substrate. Also disclosed is an adhesive coated web, comprising a substrate having at least one component susceptible to electron beam radiation degradation having no electron beam radiation modification and an adhesive layer having an electron beam modified composition and having no chemical, thermal, or ultraviolet crosslinking agent.

Adhesive coating method

A method of polishing and cleaning a glass surface with a single abrasive article. The abrasive article includes ceria abrasive particles dispersed in binder, the abrasive article having a textured, three-dimensional abrasive coating. The method includes contacting the glass surface with the abrasive article at a desired pressure and in the presence of water, and moving the abrasive article and glass in relation to each other under pressure. The water is believed to mediate a chemical reaction involving the ceria and the glass, thereby leaving a haze on the glass surface. With continued motion of the abrasive article in relation to the glass workpiece, without the addition of additional water, the haze is removed.

A novel release liner is provided which has a release surface comprising a syndiotactic polymer. The release liners of the present invention offer superior release to a wide variety of materials without the application of release agents, have relatively high heat distortion temperatures, and are unaffected by radiation sources used to cure most polymeric compositions. The release liners of the present invention can be microreplicated with a pattern which can be transferred to coatings and other impressionable materials to impart unique physical or optical properties. Thus, a method of producing a patterned article is also provided, as is a method of producing a solid object from a curable composition.
