  • Radiopaque cationically polymerizable compositions comprising a radiopacifying filler, and method for polymerizing same
    Publication number: 20060052232
    Abstract: Polymerizable compositions that include: (a) a cationically active functional group; (b) an initiation system capable of initiating cationic polymerization of the cationically active functional group; and (c) a filler composition that includes various radiopacifying fillers in an amount sufficient to render the polymerizable composition radiopaque. Components (a), (b), and (c) are selected such that the polymerizable composition polymerizes to form a polymerized composition having a Barcol hardness, measured using a GYZJ-935 meter, of at least 10 within 30 minutes following initiation of the cationically active functional group at a reaction temperature of 25° C.
    Type: Application
    Filed: November 16, 2005
    Publication date: March 9, 2006
    Inventors: Kathyrn Bretscher, Richard Rusin, Bradley Craig, Sumita Mitra, Joel Oxmann, Janis Gust, Cheryl Hayne, James Westberg, Matthew Trom, Brant Kolb, Dwight Jacobs, David Kaisaki, James Baker
  • Abrasive article packaging and method of making same
    Publication number: 20060000731
    Abstract: A system for packaging abrasive articles having an inner wrapper and an outer wrapper. The outer wrapper has a portion without vents that is positioned proximate a portion of the inner layer with vents. Aligning the vented portion of the inner wrapper and the vented portion of the outer wrapper so that they do not overlap restricts the transfer of air and moisture through the packaging system.
