HexPly® M78.1 is based on a modified, toughened epoxy resin and a highly reactive curative package applicable for pre-impregnation into carbon, glass or aramide fibers, combining the outstanding feature of being curable within e.g. 8 minutes at 120°C and with a shelf life of at least 2 weeks at ambient conditions. The versatility of HexPly® M78.1 allows a range of processing temperatures, recommended from 110°C up to 160°C. Following a cure cycle in the recommended range, HexPly® M78.1 demonstrates superior mechanical
properties and high glass transition temperatures. The controlled-flow characteristics of HexPly® M78.1 offers excellent adhesion to auxiliary and core materials like aluminum, wood, thermoplastics and elastomers. The solvent-free, non-corrosive character of HexPly® M78.1 offsets the commonly known drawbacks of in-house prepreg systems that typically include hazardous components causing limitations regarding environmental, health and safety conditions.

Technical Details & Test Data
- Curing Conditions
- Recommended heat-up rate: 0.5 – 5°C/min
- Recommended cure cycle: 15min @130°C
- Pressure gage: 1 – 10bar
Dependent on the application, alternative cure temperatures than the ones from 110 – 160°C might be applied but degree of conversion and cured Tg can deviate from stated ranges. The optimum cure cycle, heat-up rate and dwell period is dependent on component size, layup construction, oven capacity and thermal mass of tool.
