Abstract

A desensitizing agent and method which desensitizes triacetone triperoxide (TATP). The agent includes a common polymer dissolved in a volatile solvent, which allows for direct, rapid application on-site, providing for safer movement and transport of the explosive. Drop heights in impact test results of treated TATP were twice that of neat TATP or TATP treated with conventional agents. The agent is composed of non-toxic, inexpensive components with the polymer delivered in a solvent vehicle, which quickly volatilizes after application and exhibits compatibility with TATP and conventional explosives.

First claim

What is claimed is:

1. A desensitizing agent for desensitizing use on improvised and conventional explosives, comprising:
a solution of polyisobutylene and a dispersing agent in a mixture of organic solvents and lecithin being in one of a liquid and an aerosol form for application to an explosive for desensitizing the explosive from impact, friction, and electrostatic discharge in a field environment,
wherein the solution is comprised of the polyisobutylene and the lecithin in a predetermined concentration ratio by percentage by weight, and
wherein the mixture of the organic solvents comprises acetone/petroleum ether.

2. The desensitizing agent of claim 1 , wherein the improvised explosive comprises triacetone triperoxide (TATP).

3. The desensitizing agent of claim 1 , wherein the solution comprises a 20% concentration of polyisobutylene.

4. The desensitizing agent of claim 1 , wherein the solution comprises a 2% concentration of the lecithin.

5. The desensitizing agent of claim 1 , wherein the solution comprises a 20% concentration of the polyisobutylene; and a 2% concentration of the lecithin.

6. The desensitizing agent of claim 1 , wherein the solution is comprised of the polyisobutylene and the lecithin in a 10:1 concentration ratio by percentage by weight.

7. The desensitizing agent of claim 1 , wherein the solution is comprised of a 20% polyisobutylene/lecithin mixture.
