Applications & Uses
- Markets
- Composites Processing Methods
- HexFlow® RTM651 Injection Conditions
- Preheat resin to 110°C
- Preheat mold to 150°C
- Heated transfer lines should be used, 110°C recommended
- Inject the resin into the mold at 2-3 bars (minimum)
Cure Cycle
4 hours at 191°C, 5.86 bars optimal, 3.10 bars minimumPostcure Cycle
- A postcure is required to achieve the glass transition temperature and at-temperature properties shown in chart.
- Typical postcure of 16 hours at 232°C or 6-8 hours at 245°C, free standing.
- Ramp temperature from ambient to 191'°C at a rate of 3-6°C/minute and at a rate of 0.6-1.2°C/minute above 191°C.
