摘要：
The present invention provides an aqueous binder system for a coating composition, the aqueous binder system comprising A) at least 10 wt % water, based on the total weight of the aqueous binder system； B) at least one hydroxyl-functional binder polymer； and C) from 0.1 to 20 wt %, based on the total weight of the aqueous binder system, of at least one quaternary ammonium compound, wherein the quaternary ammonium compound comprises a core quaternary ammonium group which has pendant groups which comprise i) a hydrocarbyl group having 8 to 16 carbon atoms which is a linear or branched, alkyl or alkenyl group； ii) two independent hydroxyl terminated groups, wherein each hydroxyl terminated group comprises from 1 to 10 alkylene oxide residues and wherein the total number of alkylene oxide residues in the quaternary ammonium compound is from 5 to 12； and iii) a CI to C8 hydrocarbyl group； wherein B) and C) are not covalently bonded to each other within the aqueous binder system. A coating composition, a coating, methods and uses are also provided.
