Estimating the term…
An abrasive article having a sheet-like structure having at least one major surface having deployed thereon a plurality of individual abrasive composites, each abrasive composite comprising a plasticizer and a plurality of abrasive particles dispersed in a binder, wherein said binder is formed by polymerizing a binder precursor and said plasticizer being combined with said binder precursor prior to said polymerizing in an amount of 30 to 70 parts plasticizer per 100 parts by weight of the combined binder precursor and plasticizer. There is also a method of using such as abrasive article to reduce the surface finish of a workpiece and a process of making the abrasive article.
An abrasive article comprising a sheet structure having at least one major surface having deployed thereon a plurality of individual abrasive composites, each composite comprising a plurality of abrasive particles dispersed in a plasticized crosslinked binder, and said binder having been formed by crosslinking of binder precursor via an addition polymerization mechanism, wherein said binder precursor is combined with plasticizer prior to said crosslinking in an amount of 30 to 70 parts plasticizer per 100 parts by weight of said combined binder precursor and plasticizer, wherein said composites each have a precise shape defined by a distinct and discernible boundary and each composite further comprises a distal end that is spaced from said major surface and is unconnected to any other composite.
An abrasive article comprising a sheet structure having at least one major surface having deployed thereon an abrasive material comprising a plurality of abrasive particles dispersed in a plasticized crosslinked binder, and said binder having been formed by crosslinking of binder precursor via an addition polymerization mechanism, wherein said abrasive material is provided as a discontinuous raised pattern formed of a plurality of elongated three-dimensional formations extending from said major surface which define areas having no abrasive material, wherein said binder precursor is combined with plasticizer prior to said crosslinking in an amount of 30 to 70 parts plasticizer per 100 parts by weight of said combined binder precursor and plasticizer.
