Abstract
An electropyrotechnic initiator comprising a pyrotechnic varnish in contact with a resistive heating element is prepared by preparing an aqueous adhesive composed of a dispersion of an explosive substance and of additives in an aqueous suspension based on a copolymer chosen from ethylene/vinyl acetate copolymers and vinyl acetate/ethylene acetate/ethylene copolymers, depositing the aqueous adhesive on the resistive element, and drying the aqueous adhesive at a temperature of between 55° C. and 75° C., in order to remove the water contained in the adhesive and to obtain the varnish.
