Provided are low temperature curing thermosetting epoxy powder coating compositions comprising at least one non-crystalline epoxy resin, at least one crystalline epoxy resin, a curing agent, and a cure catalyst. Coatings made from such powder compositions exhibit a substantial reduction in bubble entrapment, enough to prevent a visible haze from forming in the coating, when cured at low temperatures demanded by brass substrates, while the powders from which the coatings are made still exhibit good storage stability and melt-processability.
