New isocyanato - isocyanurates, a process for their preparation and their use as isocyanate - component in the polyurethane paints

摘要

The present invention relates to isocyanato-isocyanurates corresponding to the formula ##STR1## in which X.sub.1, X.sub.2 and X.sub. 3 may be the same or different and represent radicals corresponding to the formula ##STR2## wherein R.sup.1 and R.sup.2 may be the same or different and represent hydrogen or C.sub.1 -C.sub.12 alkyl groups, and p is a whole or (on a statistical average) fractional number of from 1 to 5. PPThe present invention also relates to a process for producing these isocyanato-isocyanurates and additionally relates to the use of the new isocyanato-isocyanurates, optionally blocked by blocking agents for isocyanate groups, as the isocyanate component in the produciton of isocyanate polyaddition products, preferably polyurethane lacquers.
