Abstract
A clear coat dicyandiamide cured epoxy powder coating for non-metallic substrates wherein the finish coat is visually haze-free as a result of the addition of a small amount of an aromatic substituted urea compound. Non-metallic substrates, such as brass, cannot withstand extremely high temperatures which are required to cure well known powder coatings. However, coating systems which cure at lower temperatures often produce a haze within the finish clear coat. The present invention alleviates this problem.
