The disclosure relates to a curable composition comprising: a polymerizable epoxy-acrylate resin composition having a complex viscosity at 25° C. and 1 Hz frequency of at least about 4500 Pa-s and a probe tack peak force of at least about 300 kPa; and abrasive particles partially or fully embedded in the polymerizable epoxy-acrylate resin composition. The disclosure also relates to cured compositions formed from such curable compositions, wherein the abrasive particles are partially or fully embedded in the cured composition. In addition, the disclosure relates to abrasive articles made from such cured compositions as well as methods for making abrasive articles.

Flexible abrasive article

A shaped abrasive agglomerate particle includes a shaped abrasive particle bonded in a vitreous matrix. The shaped abrasive particles have a longest particle lineal dimension on a surface and a shortest particle dimension perpendicular to the longest particle lineal dimension, and the longest particle lineal dimension is at least twice the shortest particle dimension. The shaped abrasive agglomerate particle has a longest agglomerate lineal dimension on a surface and a shortest agglomerate dimension perpendicular to the longest agglomerate lineal dimension, and the longest agglomerate lineal dimension is at least twice the shortest agglomerate dimension. The abrasive agglomerate particles are useful in abrasive articles. Methods of making the shaped abrasive agglomerate particle and abrading a workpiece are also described.

Shaped vitrified abrasive agglomerate with shaped abrasive particles, abrasive articles, and related methods

In some examples, an abrasive particle transfer system including a production tool including a dispensing surface with a plurality of cavities formed therein; abrasive particles removably disposed within at least some of the cavities; and a nonwoven substrate having an outer surface opposing the dispensing surface of the production tool, wherein the dispending surface of the production tool is configured to apply a compressive force to the outer surface of the nonwoven substrate to compress the nonwoven substrate from a first thickness to a second thickness, wherein, while the nonwoven substrate is compressed to the second thickness by the production tool, the abrasive particles are transferred from the plurality of cavities to the nonwoven substrate.

Abrasive article and method of making the same

An abrasive article comprises abrasive particles adhered to a substrate by a binder material comprising an at least partially cured resole phenolic resin and an aliphatic tack modifier. The amount of resole phenolic resin comprises from 60 to 98 weight percent of the combined weight of the resole phenolic resin and the aliphatic tack modifier. A method of making the abrasive article is also disclosed.
