    摘要： Powder coating compositions having reduced volatility and improved processibility compared to conventional powder coatings consist essentially of a copolymer having pendant functionalities or pendant groups capable of reacting with a dicarboxylic acid such as the glycidyl groups of glycidyl acrylate or methacrylate copolymer and a cross-linking effective amount of a dicarboxylic acid. The reaction of the above pendant groups and the dicarboxylic acid cross-links or cures the powder coating after application to a substrate. The dicarboxylic acids according to the invention eliminate the need for a third component which is a flow control agent which improves the processibility of a two-component powder coating. The dicarboxylic acids according to the invention have a sublimation temperature great enough to decrease or prevent their vaporization during the curing of the powder coating and have a melting point low enough to impart improved flow properties to the powder coatings.

    摘要翻译： 与常规粉末涂料相比，具有降低的挥发性和改进的可加工性的粉末涂料组合物基本上由具有能够与二羧酸反应的侧挂官能团或侧基的共聚物组成，例如缩水甘油基丙烯酸酯或甲基丙烯酸酯共聚物的缩水甘油基和交联有效量 的二羧酸。 上述侧基与二羧酸交联的反应或在施用于基材后固化粉末涂料。 根据本发明的二羧酸消除了对改进双组分粉末涂料的可加工性的流动控制剂的第三组分的需求。 根据本发明的二羧酸具有足够大的升华温度以降低或防止其在粉末涂料固化期间的蒸发并且具有足够低的熔点以赋予粉末涂料改进的流动性质。
