ABSTRACT:
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. 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.
