Abstract
Invention relates to bismuth-containing catalysts, obtainable by reacting at least one bismuth(III) salt or bismuth(III) complex with at least one 1,3-ketoamide with the formula (I). Such complex compounds are suited in particular as catalysts for one- and two-component polyurethane compositions. The invention further relates to two-component polyurethane compositions, including at least one polyisocyanate as the first component, at least one polyol as the second component, and at least one such bismuth-containing catalyst. The invention further relates one-component polyurethane compositions, including at least one polyurethane prepolymer having isocyanate groups, produced from at least one polyisocyanate with at least one polyol, and one such bismuth-containing catalyst. The invention also relates to various uses of the aforementioned polyurethane compositions.
