An abrasive article comprised of abrasive particles and polymeric reaction product of components comprising saturated polyol, saturated polyisocyanate, and a free radical source.
An abrasive article comprised of abrasive particles and polymeric material comprised of a saturated polyurethane preparable by combining components comprising saturated polyol, saturated polyisocyanate, and a free radical source.
A method for making an abrasive article comprising:
- combining components comprising saturated polyol, polyisocyanate, a free radical source, and abrasive grains to provide a curable composition;
- and
- curing the curable composition to provide an abrasive article.
A method of abrading a surface, said method comprising:
- providing an abrasive article comprised of abrasive particles and polymeric reaction product of components comprising saturated polyol, polyisocyanate, and a free radical source, the abrasive article having an outer surface;
- frictionally contacting at least a portion of the outer surface of the abrasive article with a surface of a workpiece;
- and
- moving at least of one the outer surface of the abrasive article or the surface of the workpiece relative to the other to abrade at least a portion of the workpiece surface.
A method of abrading a surface, said method comprising:
- providing an abrasive article comprised of abrasive particles and polymeric material comprised of a saturated polyurethane preparable by combining components comprising saturated polyol, saturated polyisocyanate, and a free radical source, the abrasive article having an outer surface;
- frictionally contacting at least a portion of the outer surface of the abrasive article with a surface of a workpiece;
- and
- moving at least of one the outer surface of the abrasive article or the surface of the workpiece relative to the other to abrade at least a portion of the workpiece surface.
