β-羟烷基酰胺粉末涂料流平性能的影响因素研究

Research on Influencing Factors of Leveling Performance in β-Hydroxyalkylamide Powder Coatings

聚酯树脂粉末涂料具有高效、环保、高性能及经济性四大显著特征而受到人们的欢迎,但由于其在流平性能上略逊色于溶剂型涂料,而在某些领域的应用受到限制主要讨论酸值、黏度、酸解剂类型及助剂等因素对β-羟烷基酰胺粉末涂料流平性能的影响。

Polyester resin powder coatings are welcomed by people because of its four significant characteristics of high efficiency,environmental protection,high performance and economy,but its application in certain fields is limited due to their leveling performance is slightly inferior to solvent-based coatings.Therefore,the influence of factors such as acid value,viscosity,acidolytic agent type and additives on the leveling performance of β-hydroxyalkylamide powder coatings were discussed.
