MTM220 is a controlled flow, 120°C (248°F) curing, flame-retarded epoxy resin system developed for the manufacture of honeycomb cored structures using autoclave, vacuum bag or press moulding processes. MTM220 offers optimised tack and will bond directly to honeycomb core without the need for an additional adhesive film. This resin system also offers excellent retention of mechanical properties in hot-wet conditions and is self-extinguishing to FAR25.853, thus making it an ideal candidate material for the construction of honeycomb cored secondary structures for the aerospace sector.
