Patent 6913824 was granted and assigned to 3M on July, 2005 by the United States Patent and Trademark Office.
A method for making agglomerate particles from a composition comprising at least a radiation curable binder and solid particulates. The method comprises the steps of forcing the composition through a perforated substrate to form agglomerate precursor particles which then separate from the perforated substrate. Then, the particles are irradiated to form soldified, handleable agglomerate particles before being collected.
