Beschreibung
Zusammenfassung:	This invention relates to a crosslinking component for binder resins which is especially suitable to be used together with epoxy-group containing binders and/or (poly)isocyanates such as blocked (poly)isocyanates and which comprises at least two blocked isocyanate groups per molecule of the crosslinking component whereby at least one of the at least two blocked isocyanate groups is a group according to structural unit (I), wherein the ratio of structural units of formula (II), if present, to structural units of formula (I) is 0.40 or below. The cross-linking component may also be self-cross-linkable. The present invention further relates to a coating composition, e.g. a one-component coating composition comprising the crosslinking component and a method of its manufacture. 本发明涉及用于粘合剂树脂的交联组分，所述交联组分特别适合与包含环氧基的粘合剂和/或(多)异氰酸酯例如封端(多)异氰酸酯一起使用，并且所述交联组分的每个分子包含至少两个封端异氰酸酯基团，其中至少两个封端异氰酸酯基团中的至少一者为根据结构单元(I)的基团，其中式(II)的结构单元(如果存在的话)与式(I)的结构单元之比为0.40或更小。所述交联组分也可以是可自交联的。本发明还涉及涂料组合物，例如包含所述交联组分的单组分涂料组合物，及其制备方法。
