Abstract
An ignition enhancer coating composition for alkali metal azide pyrotechnic propellant compositions comprised of about 2 to 15 weight percent of an oxygen-containing polymeric compound; about 20 to 50 weight percent of an alkali metal azide; and about 40 to 80 weight percent of an inorganic oxidizer. This invention also relates to a pyrotechnic propellant coated with said ignition enhancer composition.
Claims8
An ignition enhancer composition for coating alkali metal azide-based pyrotechnic propellants which comprises:
- (a) about 2 to 15 weight percent of a combustible oxygen-containing polymeric compound selected from the group consisting of cellulose acetate resins and polyvinyl acetate resins;
- (b) about 20 to 50 weight percent of an alkali metal azide;
- and
- (c) about 40 to 80 weight percent of an inorganic oxidizer;
- wherein all weight percents are based on the total weight of the ignition enhancer composition.
An azide-based pyrotechnic propellant composition suitable for use in inflating an inflatable device, said composition comprising said propellant coated with an ignition enhancer composition, said ignition enhancer composition comprising:
- (a) about 2 to 15 weight percent of a combustible oxygen-containing polymeric compound selected from the group consisting of cellulose acetate and polyvinyl acetate resins;
- (b) about 20 to 50 weight percent of an alkali metal azide;
- and
- (c) about 40 to 80 weight percent of an inorganic oxidizer;
- wherein all weight percents are based on the total weight of the ignition enhancer composition.
