Process for preparing isocyanurate group-containing polyisocyanates and their use in two-component coating compositions |
摘要 |
A process for the preparation of isocyanurate group-containing polyisocyanates in solvents which are inert towards isocyanate groups by reacting 0.2 to 1.5% of the isocyanate groups of diisocyanatotoluene with an aliphatic monohydric alcohol having 6 to 22 carbon atoms and subsequently trimerizing at least a portion of the isocyanate groups of the urethanized diisocyanates in the form of 40 to 70 wt. % solutions in lacquer solvents which are inert towards isocyanate groups, and the use of these polyisocyanates in two-component polyurethane coating compositions.
