Abstract: A hydrogen gettering system for a sealed container is disclosed comprising packing material for use within the sealed container, and a coating film containing hydrogen gettering material on at least a portion of the surface of such packing material. The coating film containing the hydrogen gettering material comprises a mixture of one or more organic materials capable of reacting with hydrogen and one or more catalysts capable of catalyzing the reaction of hydrogen with such one or more organic materials. The mixture of one or more organic materials capable of reacting with hydrogen and the one or more catalysts is dispersed in a suitable carrier which preferably is a curable film-forming material. In a preferred embodiment, the packing material comprises a foam material which is compatible with the coating film containing hydrogen gettering material thereon.

Abstract: Disclosed is a process of producing microcellular from which comprises the steps of:(a) selecting a multifunctional epoxy oligomer resin;(b) mixing said epoxy resin with a non-reactive diluent to form a resin-diluent mixture;(c) forming a diluent containing cross-linked epoxy gel from said resin-diluent mixture;(d) replacing said diluent with a solvent therefore;(e) replacing said solvent with liquid carbon dioxide; and(f) vaporizing off said liquid carbon dioxide under supercritical conditions, whereby a foam having a density in the range of 35-150 mg/cc and cell diameters less than about 1 .mu.m is produced.Also disclosed are the foams produced by the process.
