| Abstract | The present invention relates to polyisocyanate mixtures having a) an average isocyanate functionality of at least 4.1, b) a (cyclo)aliphatically bound isocyanate group content (calculated as NCO, molecular weight=42) of 12.0 to 20.5% by weight, c) a chemically incorporated carboxyl group content (calculated as COOH, molecular weight=45) of 0.01 to 5.0% by weight and d) an ethylene oxide unit content arranged within terminal or lateral polyether chains of 0 to 10% by weight (calculated as CHO, molecular weight =44). |
