HexFlow® RTM230 ST

HexFlow® RTM230 ST is a monocomponent resin specifically developed for aerospace resin transfer molding (RTM) applications where high toughness is required. HexFlow® RTM230 ST is a premixed epoxy system for service temperatures up to 110°C. At room temperature, it is a gray colored paste but its viscosity decreases quickly by increasing the resin temperature.
