    Abstract: Disclosed are polyaspartic esters obtainable by reaction of at least one polyamine component A), comprising an amine compound of the formula (I), where X is a saturated or unsaturated, linear or branched, aliphatic or cycloaliphatic or aromatic organic radical which is substituted or unsubstituted and/or has heteroatoms in the chain, Y is a secondary amino group bonded to two carbon atoms, R1 and R2 independently of one another are saturated or unsaturated, linear or branched, aliphatic or cycloaliphatic or aromatic organic radicals having 1 to 18 carbon atoms, and are substituted or unsubstituted and/or have heteroatoms in the chain, and n is a natural number from 1 to 4, with at least one polyisocyanate component B), comprising a polyisocyanate which contains at least one chemically bonded, non-ionic, hydrophilic group, characterized in that the ratio of the number of secondary amino groups Y to the number of isocyanate groups in the polyisocyanate is from 250:1 to 3:1. Further disclosed is a method for producing a coating composition, a 2-component system, the use thereof for producing a coating on a substrate, and the substrates coated accordingly.

    Abstract translation: 公开了通过至少一种多胺组分A）的反应获得的聚天冬氨酸酯，其包含式（I）的胺化合物，其中X是饱和或不饱和的直链或支链的脂族或脂环族或芳族有机基团，其被取代或 未取代的和/或在链中具有杂原子，Y是与两个碳原子键合的仲氨基，R 1和R 2彼此独立地是饱和或不饱和的直链或支链的具有1至18个碳原子的脂族或脂环族或芳族有机基团 原子，并且是取代或未取代的和/或在链中具有杂原子，n是1至4的天然数，与至少一种多异氰酸酯组分B），其包含含有至少一个化学键合的非离子的多异氰酸酯 亲水基团，其特征在于，多异氰酸酯中的仲氨基数Y与异氰酸酯基的数目的比例为250:1至3:1。 进一步公开了一种制备涂料组合物，2-组分体系，其用于在基材上制备涂层的用途的方法，以及相应地涂布的基材。
