Abstract : A multiple component catalyst system for curing of energetic urethane binders for solid fuel propellants and gas generators based upon curing of glycidyl-azide polymer and isocynate curative mixtures. Void or bubble free propellant grains are obtained by employing a cure catalyst composed of a mixture of triphenyl bismuth and dibutyltin dilaurate, preferably in a respective ratio of about 10:1 by weight. The void free propellant grains have burn characteristics acceptable for missile propulsion applications.
