The present invention relates to a method for preparing an in situ cured booster explosive by coating an explosive filler with a prepolymer binder that is rubbery and pliable and desensitizes the explosive by binding together the particles of explosive filler to form a tough composite explosive. The coated explosive is pressed into pellets or billets and cured at 60 deg- 70 deg c. for about 96 hours. One object of the present invention is to make a pressed explosive safer than those made in the previous art. Another object is to make a pressed explosive that does not fracture when handled. Still another object is to make an explosive from low cost materials which are readily available. And finally, an object is to produce an explosive having high quality, and excellent reliability, and superior physical properties.
