The present invention relates to novel aspartates, their method of production and the use of these aspartates as reactive components for polyisocyanates in two-component polyurethane coating compositions and for preparing polyurethane prepolymers. The aspartaes are prepared by first reacting a di- or polyamine with an unsaturated ester and then reacting the resultant product with a ketone.
本发明涉及新型天冬氨酸盐,其生产方法以及将这些天冬氨酸盐作为双组分聚氨酯涂料组合物中聚异氰酸酯的反应组分和制备聚氨酯预聚物的用途。这些天冬氨酸盐是通过首先将二元或多元胺与不饱和酯反应,然后将所得产物与酮反应制备而成的。
