  • Monoallophanates based on alkoxysilane alkyl isocyanates
    Patent number: 10351579
    Abstract: A monoallophanate can be used in paint or adhesive compositions. The monoallophanate has the formula 1: where R, R1-R6 are each independently identical or different hydrocarbyl radicals having 1-8 carbon atoms, which may be branched or cyclic, or else may be integrated together to form a cyclic system, and m and n are each independently 0-2.
    Type: Grant
    Filed: October 11, 2016
    Date of Patent: July 16, 2019
    Assignee: Evonik Degussa GmbH
    Inventors: Emmanouil Spyrou, Manfred Kreczinski, Tobias Unkelhaeusser, Sabine Naumann, Holger Loesch, Marion Ewald, Thomas Weihrauch

  • THERMALLY POST-CURING SYSTEMS THAT CROSSLINK WITH ACTINIC RADIATION
    Publication number: 20160177123
    Abstract: A thermally curable and radiation-curable formulation, contains A) 45% to 99.9% by weight of at least one radiation-curable component; and B) 0.1% to 5% by weight of at least one selected free-radically initiating photo-initiator; and optionally C) 0.01% to 50% by weight of at least one additive; wherein the sum total of A) and B) and any C) is 100% by weight. The formulation is curable with actinic radiation and/or thermally and is used, for example, for the production of pigmented and pigment-free coating materials, and for adhesives and sealants.
