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.

Abstract: The apparatus is a contamination free stamper holder for molding discs for information storage. The stamper, the disc part of the mold holding the pits and grooves to be formed on the molded plastic, is held within the mold by one or more magnets that are completely enclosed within non-magnetic material. The wall thickness of the enclosing material between the magnets and the stamper is limited so that there is no significant loss in magnetic attraction.
