Abstract
A one-component polyurethane composition includes at least one polyurethane prepolymer having terminal isocyanate groups which is prepared from at least one polyisocyanate and at least one polyol, and to at least one catalyst system which is obtainable from at least one bismuth compound and at least one aromatic nitrogen compound. The polyurethane composition may be used as an adhesive, sealant, coating or lining. Finally, catalysts for polyurethane compositions are disclosed which represent coordination compounds between bismuth and at least one aromatic nitrogen compound.
