Abstract

A protective surface coating for ammunition having no cartridge casing and ammunition having a combustible cartridge casing. A body of highly porous nitrocellulose is permeated from the outside with a polymer carried by a solvent to form a binder for the body. A layer of metal platelets containing airpockets is bound to the body with a binding polymer. The metal platelets are covered with an outer coating of a rapidly curing resin. The protective coating is used to prevent the penetration of moisture into the porous cartridge casing or into the powder mass itself and to provide improved stability to heat and flames.
