  • Patent number: 9855639
    Abstract: An abrasive article has an abrasive portion with an organic bond and abrasive particles. The abrasive article has a non-abrasive portion (NAP) mounted to the abrasive portion. The NAP includes molding compound (MC) having chopped strand fibers (CSF). The CSF can be coated with a thermoplastic coating having a loss on ignition (LOI) of at least about 2.4 wt %, and the NAP having no abrasive particles. The NAP can include an MC having no abrasive particles with a MOHS scale hardness of at least about 9. The NAP may include CSF coated with a primary coating and a secondary coating on the primary coating. The NAP may have an outer diameter that is at least half of but not greater than an outer diameter of the abrasive article.

  • Publication number: 20140378036
    Abstract: An abrasive article may include an abrasive body having a grinding layer, where the grinding layer may include a bond and abrasive particles contained within the bond. The abrasive body also may include a volumetric ratio GLVb/GLVap of at least about 0.4, where GLVb is a volume percent of bond for a total volume of the grinding layer and GLVap is a volume percent of abrasive particles for a total volume of the grinding layer. The abrasive particles may include seeded sol-gel ceramic and may have an average particle size of at least about 600 microns. In addition, the abrasive particles may include a coupling agent that may include an organic material with a silane functional group. Prior to formation of the abrasive article, the abrasive particles may be coated by the coupling agent at a ratio ACOA/AAB of at least about 0.1, where CCOA is the amount of coupling agent in grams in a pre-formation mixture and AAB is the amount of abrasive particles in pounds (lbs) in the pre-formation mixture.
