阅读说明：本技术 基于具有空间体积大的取代基的含铋催化剂的涂料体系 (Coating systems based on bismuth-containing catalysts with sterically bulky substituents ) 是由 W-A·荣 胡蔚秋 P·霍夫曼 C·科尔顿 许华君 B·施奈尔 黄正 张延路 于 2019-03-15 设计创作，主要内容包括：本发明涉及一种涂料体系,其包含组分(A)至(C)以及任选的其他组分,其中在第一种选择中,所有组分(A)至(C)以及存在的话其他任选组分彼此分开存在,换言之,各组分不是彼此原样混合,而是仅在使用前混合。相反,在本发明涂料体系的第二种选择中,上述组分也可以全部或至少部分地彼此混合。当组分至少部分地彼此混合时,这意味着例如组分(C)与组分(A)混合,而组分(B)与(A)和(C)的混合物分开存在。然而,任选地,组分(B)也可与一部分组分(C)混合。此外,(A)和(C)的混合物以及(B)和(C)的混合物可额外包含至少一种任选组分,例如溶剂。组分(A)包含至少一种含多羟基的化合物,组分(B)包含至少一种含多异氰酸酯基的化合物。相反,组分(C)为至少一种如下文所定义的通式(Ia)和/或通式(Ib)的含铋催化剂。可存在于本发明涂料体系中的其他组分包括例如含羟基的化合物(B)、涂料添加剂(F)、颜料(H)和/或溶剂(J)。(The invention relates to a coating system comprising components (A) to (C) and optionally further components, wherein in a first option all components (A) to (C) and, if present, further optional components are present separately from one another, in other words the components are not mixed with one another as such, but are mixed just before use. In a second alternative of the coating system according to the invention, on the contrary, the above-mentioned components can also be mixed with one another in whole or at least in part. When the components are at least partially mixed with each other, this means that, for example, component (C) is mixed with component (a), while component (B) is present separately from the mixture of (a) and (C). Optionally, however, component (B) may also be mixed with a portion of component (C). Furthermore, the mixture of (a) and (C) and the mixture of (B) and (C) may additionally comprise at least one optional component, for example a solvent. Component (A) comprises at least one polyhydroxy-containing compound and component (B) comprises at least one polyisocyanate-containing compound. In contrast, component (C) is at least one bismuth-containing catalyst of the general formula (Ia) and/or of the general formula (Ib) as defined below. Further components which may be present in the coating system of the present invention include, for example, hydroxyl-containing compounds (B), coating additives (F), pigments (H) and/or solvents (J).)
