【Abstract】 Sealing and heat insulating coating matrix can be made with epoxy resin modified silicone resin. Modified resin has good features of both epoxy resin and silicone resin. The modified resin has not only excellent high and low temperature resistance, but also good strength and pliancy. It can be used as sealing and heat insulating coating material for composite case of solid rocket motor through adding some proper fillings.This coating has high sealing ability against gas and broad temperature adapting range as well as good water endurance ability and salt water endurance ability.更多还原
