摘要：The invention relates to the use of hydroxyl- and fluorine- containing acrylatecopolymers as additives for aqueous anionic coating systems for preventing surfacedefects. …The acrylate copolymers contain, in addition to bases of neutralisable carboxylgroups, in a selected amount, esters of (meth)acrylic acid containing fluorine andhydroxyl groups originating from hydroxyethyl or hydroxypropyl (meth)acrylates. …Theadditives are added in an amount of from 0.1 to 2.0 % by weight, calculated as a solid andbased on the solid content of the binder in the coating composition.
