Abstract
Storage-stable metal-fueled pyrotechnics and methods for manufacturing such compositions are provided. These are manufactured by granulating a mixture of liquid cyclohexane, powdered metal fuel, optional Teflon.RTM. powder, and at least one ethylene and vinyl acetate co-polymer, together to form a storage stable powdered metal fuel effectively coated with ethylene and vinyl acetate co-polymer. This provides pyrotechnics with superior resistance to degradation induced by atmospheric moisture, and having other improved properties. The powdered metal fuel includes, for example, powdered magnesium.
