Process for the production of compounds containing isocyanurate groups and olefinic double bonds, the compounds obtainable by this process and their use as binders or binder component in coating compositions

摘要

A process for the production of compounds which crosslink under the effect of high-energy radiation containing isocyanurate groups, olefinic double bonds, and, optionally, blocked or free isocyanate groups by reacting (i) isocyanurate-group-containing polyisocyanates which are based on aliphatic and/or cycloaliphatic diisocyanates with (ii) compounds containing at least one isocyanate-reactive group and at least one olefinic double bond, such as hydroxyl-containing esters of acrylic acid and methacrylic acid with at least dihydric aliphatic alcohols having a molecular weight of from 62 to about 300, to form urethanes, the quantitative ratios between the reactants being selected so that for every free isocyanate group in component (i), the reaction mixture contains from about 0.9 to 1.5 hydroxyl groups of component (ii). The present invention also relates to the compounds prepared by this process and to the use of these compounds as the binder or a binder component in coating compositions crosslinkable by high-energy radiation.
