  • Patent number: 6913824
    Abstract: 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.

  • Patent number: 6620214
    Abstract: Methods for making ceramic aggregate particles comprising forming a plurality of ceramic aggregate precursor particles from a composition by forcing the composition through at least one orifice in a substrate, at least partially curing the ceramic aggregate precursor particles, and heating the ceramic aggregate precursor particles to provide ceramic aggregate particles wherein solid particulates are bonded together by ceramic binder.

  • Patent number: 6521004
    Abstract: A method for making abrasive 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.

  • Patent number: 6475253
    Abstract: This invention pertains to a coated, bonded or non-woven abrasive article containing precisely shaped particles and a binder. These precisely shaped particles can contain abrasive grits, fillers, grinding aids and lubricants. The binder is preferably a mixture of a resole phenolic resin and a free radical curable resin, resulting in improved cutting and life span. Also disclosed is a method of forming the coated, bonded or non-woven abrasive article.

  • Patent number: 4798741
    Abstract: Pigment particles of a suitable size are microencapsulated by mixing them in a gelatin solution, coacervating the gelatin to coat them, cooling to set the gelatin, adding formaldehyde to harden the particles, sequestering unreacted formaldehyde with a bisulfite, adding gelatin to coat the hardened particles, precipitating the particles chemically or physically, and washing the precipitate.
