Abstract (en)
[origin: US2008318060A1] Polyisocyanate mixtures, their preparation by reacting aromatic polyisocyanate mixtures and nitrogen-containing polyetherol mixtures, and their use as an isocyanate component for the preparation of moisture-curing adhesives, said polyisocyanate mixtures comprising: (A) 15 to 35 wt. % of diphenylmethane diisocyanate with 2 aromatic rings; (3) 10 to 30 wt. % of polymeric diphenylmethane diisocyanate with 3 or more aromatic rings; and (C) 40 to 75 wt. % of an isocyanate-functional polyurethane; wherein the polyisocyanate mixture has an isocyanate content of 12 to 20 wt. %, an isocyanate functionality of >2.4, a viscosity of <10,000 mPa.s at 25° C., and a shear rate of 80 l/s.
