    摘要： A high-reactivity liquid polyurethane composition which contains at least one uretdione group and cures at a low baking temperature can be used for producing plastics, particularly surface coatings and adhesives. The polyurethane composition contains A) at least one curing agent which contains at least one uretdione group and is obtained from i) an aliphatic polyisocyanate, a (cyclo)aliphatic polyisocyanate, a cycloaliphatic polyisocyanate or mixtures thereof, and ii) at least one hydroxyl-containing compound, the curing agent having a free NCO content of less than 5% by weight and a uretdione content of from 1 to 18% by weight; and B) at least one catalyst.
