泡沫涂料组合物和用此涂料组合物涂敷基材的方法
摘要：
本发明涉及一种涂敷基材的方法，包括a)提供液体水性涂料组合物，该组合物包含丙烯酸系树脂作为基料、一种或多种表面活性剂、聚结溶剂和增稠剂；b)使该液体水性涂料组合物发泡而得到泡沫涂料组合物；c)将该泡沫涂料组合物的层施加于该基材上；以及d)使气体从该泡沫涂料组合物的层逸出并使该涂料组合物干燥而形成均匀非泡沫干燥涂层，其中在步骤a)中提供的液体水性涂料组合物基于该液体水性涂料组合物的总重量包含浓度为1‑20重量％的丙烯酸系树脂，包含浓度为0.05‑2.0重量％的增稠剂并且具有至多25重量％的固体含量。本发明进一步涉及可以由步骤a)和b)得到的泡沫水性涂料组合物。
摘要（英）：

The invention relates to a method for coating a substrate comprising: a) providing a liquid aqueous coating composition, the composition comprising an acrylic resin as binder, one or more surfactants, a coalescence solvent, and a thickener; b) foaming the liquid aqueous coating composition to obtain a foamed coating composition; c) applying a layer of the foamed coating composition on the substrate; and d) allowing gas to escape from the layer of foamed coating composition and allowing the coating composition to dry to form a homogeneous non-foam dried coating, wherein the liquid aqueous coating composition provided in step a) comprises the acrylic resin in a concentration in the range of from 1 to 20 wt %, comprises the thickener in a concentration in the range of from 0.05 to 2.0 wt %, and has a solids content of at most 25 wt %, based on the total weight of the liquid aqueous coating composition. The invention further relates to foamed aqueous coating composition obtainable by steps a) and b).
