Abstract
The present invention relates to zinc(II) complex compounds of the formula Zn(L)x(Y)2-x, wherein the ligand L has the formula (I). Such complex compounds are particularly suitable as catalysts for two-component polyurethane compositions. The invention also relates to two-component polyurethane compositions including at least one polyisocyanate as a first component, at least one polyol as a second component and at least one such zinc(II) complex compound as a catalyst. In addition, the invention relates to various uses of these two-component polyurethane compositions.
