a viscosity of about 50 poise and a functionality of 2 6 the dimethyl hydantoin dhe compound is especially useful for bonding oxidizers in composite propellants or explosives while not intending to be bound by any particular theory it is postulated that the dimethyl hydantoin functions as a bonding agent by complexation while explains its use with a wide variety of binders and fillers for example with hmx and rdx the hydantoin is believed to form a complex with the complex being amendable to bonding in the binder the hydantoin is believed to be the only bonding agent known at this time for bonding hmx or rdx in a composite propellant or explosive up to about 5 hydantoin is suitable with 0 3 to 0 7 hydantoin by propellant weight preferred of the many known oxidizers only a few are compatible with binder systems using a hydantoin bonding agent cyclotrimethylene trinitramine rdx and cyclotetramethylene tetranitramine hmx are strongly bound in binders using hydantoin bonding agent a complexing reaction is believed to account for the strong bond ammonium perchlorate ammonium nitrate and potassium perchlorate are also strongly bonded in a binder by using dimethyl hydantoin bonding agent it is also possible to use mixtures of oxidizers in the binder as well as various fuels and propellant adjuvants compositions using the dimethyl hydantoin as a bonding agent are also easier to work with in casting molding extruding or mixing processes solubility of the hydantoin in polymer causes no problem the hydantoin also functions as a hardener mechanical properties at low temperatures.
