THERMOSETTING POWDER COATING COMPOSITIONS

摘要

2138025 9401505 PCTABS00030 Provided are thermosetting coating compositions comprised of a coreactive mixture of a glycidyl group containing acrylic polymer and an aliphatic carboxyl functional polyester, e.g., poly(tetramethylene trans-1,4-cyclohexanedicarboxylate) along with an aliphatic polycarboxylic acid. The coatings obtained from the application and curing of these compositions possess excellent weathering properties.
