Additives for powder coatings |
摘要 |
<p>Copolymers containing fluoro groups and hydroxyl groups are used as additives in powder coating materials, by mixing the copolymers with powder coating resins. <??>Use of copolymers containing fluoro groups and hydroxyl groups as additives in powder coating materials, comprises mixing the copolymers with powder coating resins. The copolymers comprise: <??>(a) olefinically unsaturated monomers having 5-40C, with a hydroxyl group(s) and a free-radically polymerizable C=C bond; <??>(b) alkyl esters of monoolefinically unsaturated monocarboxylic acids or dialkyl esters of olefinically unsaturated dicarboxylic acids or their mixtures, the alkyl radicals having 1-18C, and the carboxylic acids having 3-12C; and <??>(c) (per)fluoroalkyl esters of the carboxylic acids, the (per)fluoroalkyl group having 2-20C.</p> |
