A new process for reducing the monomer content of urethane or isocyanurate-modified polyisocyanates based on (i) 2,4- and optionally 2,6-diisocyanatotoluene, (ii) mixtures of the diisocyanates mentioned under (i) with up to 80 NCO- Equivalent percent, based on the mixture, of 1,6-diisocyanatohexane or (iii) 1-isocyanato-3,3,5-trimethyl-5-isocyanato-methyl-cyclohexane by adding water, the modified polyisocyanates obtainable by this process and their Use as a binder or binder component in one- or two-component polyurethane coatings. |
