MTM 46

Product functions: High Service Temperature (>150°C)
MTM46 is a high performance, 135°C (275°F) curing, toughened epoxy resin formulated for the production of aircraft structures (FAR23 aircraft and unmanned air vehicles (UAVs). MTM46 exhibits excellent retention of Tg under wet conditions. MTM46 can be processed via low pressure vacuum-bag Out-of-Autoclave (OoA) moulding or autoclave moulding. MTM46 can be cured at temperatures as low as 80°C (176°F), allowing the use of low cost tooling for prototypes and short production runs. MTM46 meets NASA outgassing requirements and can be used in space structures.Meets NASA outgassing standards when tested to ECSS-Q-ST-70-02C.
