  • Patent number: 6830816
    Abstract: The present invention relates to a composition containing silico-organic nanohybrid and/or microhybrid capsules for scratch-resistant and/or abrasion-resistant coatings, wherein the silico-organic nanohybrid and/or microhybrid system includes one or more small metal oxide cores A and a substantially complete, silico-organic shell B, and the composition can be obtained by a reaction performed in situ, in a synthetic resin or in a synthetic-resin precursor compound, between metal oxide particles (KA-O) and at least one organofunctional silicon compound which contains an organofunctional group and at least one hydrolyzable group or at least one hydroxy group. The present invention also relates to the use of such compositions as the base for lacquers for producing a scratch-resistant and abrasion-resistant coating on a substrate as well as articles provided with corresponding scratch-resistant as well as abrasion-resistant coatings.
    Type: Grant
    Filed: April 1, 2002
    Date of Patent: December 14, 2004
    Assignee: Degussa AG
    Inventors: Reiner Mehnert, Hans-Juergen Glaesel, Helmut Langguth, Jaroslaw Monkiewicz, Roland Edelmann, Bjoern Borup
  • Patent number: 6699586
    Abstract: Organosilicon nano/microhybrid systems or microhybrid systems having nanoscale and/or microscale oxide particles (KA—O), and an organosilicon shell with at least one organosilicon constituent of the general formula Ia wherein the organosilicon constituent of the shell B is attached to the oxide particles via one or more covalent linkages of formula Ib A process for preparing a composition comprising organosilicon nano/microhybrid systems or microhybrid systems directly in a synthetic resin composition allows in situ preparation of a curable resin. The compositions may be used as coating materials for producing scratch resistant and abrasion resistant coatings.
