RTM 6 - 1

180 C epoxy system for Resin Transfer Mouldii monocomponent system Product Data HexFlow® RTM 6 is a monocomponent resin already degassed, specifically developed to fulfil the requirements of the aerospace and space industries in advanced resin transfer moulding (RTM) process HexFlow® RTM 6 is a premixed epoxy system for service temperatures from -60°C up to 180°C (-75°F up to 350°F). At room temperature, it is a brown translucid paste but its viscosity decreases quickly by increasing ■ Already degassed. Ready for use ■ High glass transition temperature ■ Excellent hot/wet properties ■ Easy to process (low injection pressure) ■ Long injection window < 150 min at recommended injection temp ■ Short, simple cure cycles HexFlow® RTM 6 resin is available with a wide range of Injectex®, HexForce® and multiaxials (carbon, glass aramid, hybrid) ■ Shelf Life @ 23°C 15 days maximum ■ Guaranteed Shelf Life @-18°C 9 months Typical Resin Properties
