Non-yellowing degassing compositions which enhance degassing in powder coatings and other film-forming curable coatings are disclosed. The non-yellowing compositions contain degassing agents including a plurality of unfused aromatic rings and at least one functional group selected from ketals, carbamates, carbonates and carboxylic acid esters. The degassing agents resist decomposition and discoloration, and are relatively stable at resin curing conditions and. The degassing agents may be synergistically combined with other materials, such as fatty acid amide-containing waxes, to produce new and surprisingly effective degassing compositions suitable for use in powder coatings. Curable compositions which utilize the new degassing compositions are also disclosed.
本发明公开了可提高粉末涂料和其他成膜固化涂料脱气性能的非黄变脱气组合物。非黄变组合物含有脱气剂,脱气剂包括多个未融合的芳香环和至少一个选自酮、氨基甲酸酯、碳酸盐和羧酸酯的官能团。脱气剂可防止分解和变色,在树脂固化条件下相对稳定。脱气剂可与其他材料(如含脂肪酸酰胺的蜡)协同组合,生产出适用于粉末涂料的新型高效脱气组合物。此外,还公开了使用新型脱气组合物的固化组合物。
