  • 2K polyurethane systems with phase separation
    Patent number: 10131738
    Abstract: The invention relates to a two-component polyurethane composition containing i) 10 to 80 wt. % of at least one polyol with an average molecular weight of 200 g/mol to 3000 g/mol, ii) 5 to 60 wt. % of at least one aromatic polyisocyanate, and iii) 0 to 15 wt. % of an additive. The composition has an NCO:OH ratio of 2:1 to 1:2, and the composition has a viscosity of 20 to 3000 mPas (EN ISO 2555, Brookfield viscometer, 25° C.) and displays a phase incompatibility after the mixing process. The functionality of the polyol mixture is greater than 2.3.
    Type: Grant
    Filed: August 25, 2014
    Date of Patent: November 20, 2018
    Assignee: Henkel AG & Co., KGaA
    Inventors: Andreas Ferencz, Lothar Thiele, Tamara Schmidt, Konrad Becker, Wolfgang Lupp, Dustin Ullmann, Oliver-Kei Okamoto
  • 2K polyurethane systems with a high glass-transition temperature
    Patent number: 10093766
    Abstract: A two-component polyurethane composition with a viscosity of 20 to 3000 mPa·s (EN ISO 2555, 25° C.), containing i) 10 to 80 wt. % of at least one polyol with a number-average molecular weight of 200 g/mol to 3000 g/mol, ii) 5 to 70 wt. % of at least one polyisocyanate, iii) 0 to 10 wt. % of a catalyst, wherein the composition has an NCO:OH ratio of 2:1 to 1:2 and polyisocyanates are used, wherein 3 to 25 mol % of the NCO groups of the polyisocyanate are converted into carbodiimide and/or uretonimine. The two-component polyurethane compositions are used as matrix binders for fiber composite moldings.
