Novel Protective Coatings for Ammonium Dinitramide
Ammonium Dinitramide (ADN) is a potential eco-friendly alternative to more toxic oxidizer ammonium perchlorate (AP) in solid rocket propellants. It is dense, chlorine-free and powerful oxidizer. However, it has a low melting point and highly hygroscopic in nature. It is also incompatible with common urethane-based binders used in explosives and propellants. Therefore, ADN particles need to be protected from moisture and reacting with isocyanate curing agents. In this Phase I effort ADN particles will be encapsulated with a variety of coating materials. The encapsulated ADN powders will be evaluated for improvements in sensitivity and moisture stability and compared against commercial ADN materials.
