Abstract
The present invention relates to iron (III) complexes of the formula Fe(L)x(Y)3-x, where the ligand L has the formula (I). Such complexes are especially suitable as a catalyst for two-component polyurethane compositions. The invention also relates to two-component polyurethane compositions comprising at least one polyisocyanate as the first component, at least one polyol as the second component and at least one iron (III) complex of this kind as a catalyst. In addition, the invention relates to various uses of these two-component polyurethane compositions.
