Control of cure rate of polyurethane resin based propellants
摘要:
Curing catalysts comprising organo metallic compounds, and carboxylic acids or compounds convertible thereto, processes for their use and compositions containing them are disclosed. The compositions enable the control of the curing rate profile of hydroxy terminated polybutadiene based urethane propellant binders, and the cure rate profile of polyurethane resin systems generally.
