Aqueous coating compositions pigmented with flake-form metallic effect pigments, processes for preparing them and use thereof for producing multicoat paint finish
Abstract:
Disclosed are curable aqueous coating compositions comprising at least one polyurethane (A) as binder, at least one laminar metallic effect pigment (B), and at least one inorganic thickener C1) selected from the group of the phyllosilicates, and at least one organic thickener C2) selected from the group of the (meth)acrylic acid-(meth)acrylate copolymer thickeners and polyurethane thickeners, where the amount of B), based on the total binder content of the coating material composition is >9% by weight, the total solids based on the coating material composition is between 12.5% and 17% by weight, the total amount of the thickeners C1 and C2), based on the total binder content of the coating composition is 0.4, and the amount of B), based on the coating material composition, is between 1.2 and 2.3% by weight.
Abstract(Chinese):

公开了包含至少一种作为粘合剂的聚氨酯（A），至少一种层状金属效应颜料（B）和至少一种选自页硅酸盐的无机增稠剂C1）和至少一种有机增稠剂 C2）选自（甲基）丙烯酸 - （甲基）丙烯酸酯共聚物增稠剂和聚氨酯增稠剂，其中B）的量基于涂料组合物的总粘合剂含量> 9重量％， 基于涂料组合物的总固体为12.5重量％至17重量％，增稠剂C1和C2的总量）基于涂料组合物的总粘合剂含量为<12.5重量％，重量比为 C2）至C1）为> 0.4，并且基于涂料组合物的B）的量为1.2-2.3重量％。
