Abstract (en)
[origin: EP0008265A1] 1. A process for the manufacture of pyrotechnic charges from plates of powder having a thickness which is substantially constant, according to which process a viscous composition of a material which is an inhibitor of combustion is prepared for deposition on the plates, characterized in that : - said composition is prepared from a constituent selected from the group represented by organic resins which are moisture-polymerisable, and by silk-screening inks having a polyester base, to which is added at least one propellant stabilizer ; - a silk-screening screen is positioned on one of the faces of the powder plate, said screen having a series of apertures regularly distributed thereon ; - the viscous combustion inhibiting composition is applied to the screen and is spread thereon ; after which, - the screen is withdrawn so as to allow polymerisation of the combustion inhibiting composition disposed on the powder plate.
