USE OF ACRYLATE COPOLYMERS AS ADDITIVES FOR AQUEOUS CATIONIC COATING SYSTEMS |
摘要 |
2420/US3490 Acrylate copolymers containing amino, hydroxyl and fluorine groups useful as additives for aqueous cationic coating systems for preventing surface flaws and for improving the adhesion of further coats, in particular of PVCcontaining coating materials, are described. In addition to amino groups which can be neutralized with acids, the acrylate copolymers contain a selected quantity of hydroxyl groups originating from monoesters of (meth)acrylic acid with diols, and fluorine from esters of (meth)acrylic acid. The additives are added in a quantity from 0.5 to 5.0% by weight, calculated on solids and relative to the solids content of the binder in a coating system.
