METHOD OF MAKING ABRASIVE AGGLOMERATE PARTICLES AND ABRASIVE ARTICLES THEREFROM

摘要

A method for making abrasive agglomerate particles from a composition (12) comprising at least a radiation curable binder and solid particulates. The method comprises the steps of forcing the composition through a perforated substrate (56) to form agglomerate precursor particles (20) which then separate from the perforated substrate. Then, the particles are irradiated to form solidified, handleable agglomerate particles before being collected. The particles may be used to make abrasive articles that include a backing, abrasive agglomerate particles and a bonding medium to adhere the abrasive agglomerate particles to the backing.
